Starting my first grow. Germinated 2 Candy Kush Auto seeds using Jiffy peat plugs and transferred seedlings to 6" planters about 2 weeks ago. As can be seen from photos first set of leaves are turning yellow and new growth seems extremely slow ??? with the leaves curling downward.
Grow Box: 15" W x 11.5" L x 32" H
Lighting: started with 3 60 watt CFL, tried 3 100 watt CFL and about 3 days ago switched to 150 watt UFO LED light. / Plants are now about 8" from LED and are on a 18/6 light/day cycle.
PH: Was close to 7.0 / Purchased new gallon of distilled water and added PH Down to test out at 6.0 - 6.5 PH.
Humidity: 30% - 42%
Temp. The grow box has both 3" intake/exhaust fans. Added a small 4" fan to increase circulation. Temp in grow box has been running at about 90F and higher when using the CFL lighting. Switching to LED grow light did not change temp much, has been at about 90F. Adding 4" fan has lowered temp by 2 - 3 degrees.
Soil: 50/50 mix of Scotts Premium topsoil, Kellogg Organic Garden Soil (30,10,10), and Perlite.
Nutrient: Added Foxfarms Grow Big / Mixed 1 teaspoon to 1 gallon water. First feeding was today.
Watering: About every-other day
When first transferred to soil, the seedlings looked great, but growth has not been what I expected and am now geeing worried with the yellowing / curling leaves. Have added bowl of water/wet towels to attempt to increase humidity and am considering leaving off grow box door to lower temps. Any suggestions/advise would be greatly appreciated.
@Stvzie… Your have two types of soil, one has nitrogen at 30, the Scott’s soil, who knows what’s in it? And you added grow big which has nitrogen… IMHO there is way too much nutes to such a young plant… Plan on just ph’d water for the near future until plant re establishes itself…
Good luck with your grow… She will be ok, no more nutes until it matures
I would say the soil is hot for a seeding meaning it has too many nutrients in it, that and the additonal nutrients that were given is too much for it. As @Zombo said best to give it only PHd water for a while until it gets larger.
Hey brother @Stvzie imo, im still learning myself too but i know your feeding way to much for a young plant. Just give plain ph water for a couple weeks for now until your ppm run off drops and also you have your light to close to your babys. Raise your light up to 12 inches to 18inches. Your temps are really high also, try 1 150w cfl for now until your babys get to like 6-8 inches tall an have some new growth an then add your leds or other cfls. I would mist them also with ph water a couple times a day until some new growth shows. Try that an see how they do for a week. Just tryin to help you out brother. Id hate to see you loose your babys man. Good luck bro
You don’t want ANY nutes until your plant is a foot high, with the hot soil you have. If you haven’t already, you really should pick up a ph measuring kit (digital or liquid) and start watering at a known 6.5 ph. You are doing the right thing to try to get the temps down IMO.
Are there signs of over watering? As @Stvzie said: at this point a spray bottle of ph 6.5 water a couple of times per day is plenty.
Hi everyone, thanks for the advice.
So no longer using nutrients, using PH water that’s near 6.5 - 6.0, and am going to stop water as much. Maybe just misting couple times a day. Have also raised LED light to about 14" from plants. Will update in a few days/upload pics
So my baby girls haven’t been growing much at all and still have leaves turning yellow, drying up and dropping off. Today I went and purchased a bag of Fox Farms Happy Frog potting soil and have transplanted both girls into 3 gallon cloth planters. Hopefully in a few days I will start seeing improvements
So its been a week since transplanting to new soil/smartpots. My baby girls are looking much better now. I’m going to wait a few more days before I attempt any sort of nutrient feedings. Temps have been running extremely high during the day with the lights (+95 - 100)degrees and humidity is under 30% during the day. Have been misting plants 2 -3 times a day. Have included couple pics
Hi, Happy Labor Day. It’s been 22 days since my babies were transplanted into the FF soil. Think their looking good. The girls have been feed several times now with FF Big Grow nutrients using a alternating schedule of PH’ed water and then FF Big Grow nutrients. Have also been misting the plants 2 - 3 times a day.
Have been anxiously checking for preflowers past week, have been worried that stress from the early nutrient burns/heat might have caused the girls to go male/hermy on me!!! Havn’t seen anything that looks like balls yet. Today I saw my first preflower pistils on the baby girls. I’m going to continue with the FF Big Grow for another week. Hoping to start seeing a lot more preflowers/pistils. The seed bank I purchased from states that these Candy Kush autos should complete in about 70 days. I think its going to take longer.
So its been another week and have contined to see preflowers/pistils growing. Have switched the lighting to 4 23 watt 2700 K CFL’s. Briefly tried using 6 23 watt CFL lights but quickly backed down to the 4 lights due to temps over 100 F. Have continued with FF Big Grow Nutrients and on Sunday I started feeding with FF Big Bloom. Have been alternating watering with nutrients and straight ph’ed water. Am also continuing with folier misting of the plants with a weaker solution of ph’ed water and FF Big Grow, but am considering stopping that as the flowers continue to grow.
At what strength are you using grow big? That’s a strong nute. Fox farm makes a foliar spray called flowers kiss , it’s a lot better to use trust me I use the whole fox farm liquid nute line . Yes it can be used that way but must be very careful. 1/2 tsp per gal water ever other week. I would suggest that you use big Bloom at 1 tsp per gal water every week. It’s a lot more forgiving.
I’ve been using 1 Tbsp per 1 gallon of water of FF Big Grow past couple weeks, and about 1/2 Tbsp of the FF Big Bloom added to the same mix as of Sunday. As I see the buds develop more may cut back on the Big Grow and increase the Big Bloom mix. I am still alternating with pH’ed water and the nutrient mix. about everyother day.
