Need Help Identifying Problem!


#1

Hello experienced growers. I am a total newbie, working on my first Sour Tangie clone plant. Everything was going great until a week or so ago, then several of the large fan leaves halfway up the plant began to look sick (see pics below).

I think the problem may have been nutrient starvation because I probably left the plant in a 10" pot far too long and she may have consumed everything in the pot by the time I transplanted her yesterday. She was about 22" tall and quite root-bound.

Notice her tops are looking pretty healthy and lively, not sure, but I think she is looking better today, but the fan leaves look same/worse, and there seem to be more of them with the problem now.

I transplanted her into a 10 gallon cloth pot with Fox Farms Ocean Forest potting soil. PH testing indicates the water I am using is at 6-6.5 so no problem there. I have a fan on her most of the time and she’s sitting right under the window with a 2x2’ bank of led lights above about 3" and 3 100W CFLs.

I have not added any fertilizer after the re-potting yet, but plan on using BioThrive Bloom plant food (2-4-4) since I was intending to flip the lights to 12/12 as soon as she feels/looks better.

I could really use some feedback from you guys on what might be the problem if anyone has an idea.Thanks in advance!!

Welcome to the forum @burle. You gave quite a bit of info but if you fill out a support ticket that will give us more info to help figure out what’s going on. I’m the worst person when it comes to diagnosing issues so will tag a few people for you. @garrigan65 @Hogmaster @Countryboyjvd1971 @raustin @dbrn32 @WillyJ @Screwauger

Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so = NA

Strain; Type, Bag seed, ILGM… name of strain:

How many plants:

Age from Sprout and Flower:

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots:

How often do you water and how do you determine when to do so?

PH of water and runoff or solution in reservoir:

What is strength of nutrient mix? EC, or TDS:

Indoor or Outdoor:

Light system, size and height from plants:

Temps; Day, Night:

Humidity; Day, Night:

Ventilation system; Yes, No, Size:

AC, Humidifier, De-humidifier:

Co2; Yes, No:

Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but short, to the point questions and facts will help us help you

Hi @AnneBonny, Thank you for your response. I’m not sure if you intended for me to enter a support ticket as well as answer the questions you asked, so I’ll try to do both:

Strain; Sour Tangie

How many plants: 1

Age from Sprout and Flower: Clone, estimating about 6 weeks since cloning

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: Fox Farms Ocean Forest upon transplant to 10 Gallon cloth pot - just transferred from 10" clay pot with Miracle grow potting soil

How often do you water and how do you determine when to do so? Not sure on new container yet, had been about every 3 days in the clay pot, depending on feel of soil

PH of water and runoff or solution in reservoir: Runoff n/a, water about 6 to 6.5

What is strength of nutrient mix? EC, or TDS: 5-4-2, but hadn’t really used it much

Indoor or Outdoor: Indoor

Light system, size and height from plants: 1ft X 2ft full spectrum LED + 3x100W CFL

Temps; Day, Night: 71 / 50

Humidity; Day, Night: Day = 50%

Ventilation system; Yes, No, Size: Yes - small fan, not too aggressive

AC, Humidifier, De-humidifier: None

Co2; Yes, No: No.

If you just transplanted into fresh ocean forest keep watching that new growth. I’m going to guess your diagnosis is correct. About the only other thing I would suggest is keeping an eye on runoff ph and ppm.


#5

@dbrn32 thank you for your help. I looked closely for parasites and continue to see none so I’m thinking nutrient deficiency is the problem. I’ll follow up as we go.

Speaking of parasites, is it a bad idea to spray with something like Pest Fighter oil? maybe wait to see what happens first? Not sure how to test for ppm.


#6

How far above the top of plant are the led lights reason I am asking is if you are useing led u need to be min of 36 inches above tops do to led intensity of light will make leaves brown and die look a lot like nutrient burn I only know because I had same issues when I grew with led lighting so if led is 3” away from tops that’s way to close. It really dose look like light intensity burning


#7

@BigDaddyCain I can’t believe I missed that! I have been running my LEDs as close as possible or around 2-3" above the tops and I can’t recall how I decided that was the right height, but you’re right - it is WAY too close.

I just read this ILGM blog on LED lighting and it says to keep these lights at least 12-18" above the tops. I’m also embarrassed to admit that I just read the box that packaged my LED lights which say minimum 18" - 24" above the tops. Jeez.

Thank you so much for this feedback @BigDaddyCain - I just raised the lights to 18" which is the maximum travel for the system I built, but will stop by the the Home Depot for more tubing to extend its range later today.

No problem we are all still learning even pros are learning new tricks every grow they do. For your other question u can get a cheap ppm tester pen type pretty cheap on eBay like 12 bucks also get a ph that is the most important num


#9

Are those fan leaves original to the clone if so they will probably die off @dbrn32 is on pointvwatch fir new growth since you just transplanted it
I would also keep ph above 6.3 on your runnoff anything below can cause issues
6-8 weeks isn’t abnormal fir a clone before it starts to look great again especially if you rerooted in soil
Happy growing
Thanks fir the tag @AnneBonny

Hi @Countryboyjvd1971, the fan leaves grew after cloning, but early on. I haven’t tested the runoff yet but will do so moving forward. I’m assuming the right thing to do is make the PH adjustment to everything I put in the soil including the liquid nutrients, right? So if the runoff PH is low but the PH of whatever liquid gets added to the soil is correct, I would need to add something like PH Up in small steps, right? Or should I just adjust the water I add?


#11

Ok You don’t add ph before nutrients always after u mix up what u are useing nutrient wise that is also so u don’t nut burn them alternate food and plane water so if u are water one time every 3 to 4 days do nutrient then plain water then nut then plain will help stop the neut burn then when they get bigger like makeing u water 2 to 3 times a week then it is nuitrient then plain 2 times then nutrient your plants will love you for it


#12

@BigDaddyCain so I understand the alternating of nutrients and watering days, that makes sense to me. Then for correcting ph, it sounds like I adjust the ph of the nutrients after mixing up a batch, is that correct or am I missing it?


#13

Correct ph after you mix


#14

Yup adjust pH after adding nutes to your water
Welcome to the forum
She will make it just follow the direction given
@BigDaddyCain and @Countryboyjvd1971 are sharp cats
Thanks for posting
We all learn from each other
Welcome glad your here


#15

Thanks for the words of welcome, good to be here too! I raised the lights to 24" yesterday and watered again afterwards.now the tops look really good. Their leaves were starting to look yellow around the veins, now they are a healthy deep green all the way across. Thanks again to all mentors!

@Growit @BigDaddyCain @Countryboyjvd1971 I am now in flowering mode, 25 days have passed since going 12-12 and my plant looks pretty skinny and buds look small (pic below). I did very little topping but the Sour Tangie strain is known to grow a lot so I’m not sure if my plant is actually typical in her skinny-ness.

I guess the big question is what to do with the six clones I generated from her (see pics). They will be raised outdoor this time, hoping the sun and lots of topping will help increase density of the plants and bud size. Any suggestions at this point?


#17

The buds will fatten up over the next few weeks looks like you might have a 10 to 12 week flower I was supposed to cut mine down today but I’m going to give them probly another week of flush so they can ripen more and this is the start of week 10 so let them grow they will fatten up as you see not enough amber tries


#18

@BigDaddyCain, thank you for your response. Wow! I’ll be one happy camper if my buds look even close to the way yours look now!

Yea, I know I need to be patient, just looks like my plant is kind of lanky - do you think I should have been more aggressive on the topping and maybe done some of the other pruning techniques like lollipopping or tying branches down, etc?

I think maybe the Sour Tangie strain might tend to be less bushy than other strains, but can’t find anything on line to back that up. The clones I created are outdoor plants and are looking just as stringy as their mom.

– Beej.


#19

Could be the strain but normally when they are stretchy like that it’s lack of light but some strains are lust stretchy. Also any plant can be a bush if probly trainer topping gives more colas and fimming makes them bushy
