Young auto flower Gelato with yellowing spots

this is under 1000w MH, 5X5X80" tent, using Fox Farms Happy frog, using a wick in water/nutrient solution. Recently added water soluble fertilizer with higher nutrition.

I have gorilla glue, girl scout in same tent, same everything doing fine it appears fine

This is yesterday and today

Temperature ave. 77°F but humidity is low around 30

The pro’s might be able to help you out more but if you’re using FFHF, you shouldn’t need to add ANY nutes for about 4 weeks. I think too many nutes is your problem. I use the same soil and just started giving them the min amount of nutes mid week 4. Hope this helps!

PS, it’s winter here in Chiraq so even with a humifier, the max RH I got was 35%. I wouldn’t worry too much about it.

I’m about 60 miles from you…

Thanks, I was wondering about the nutes. I saw somewhere HF has a less nutes than Ocean forest… so I added a 1/4 diluted mix. The others seem to doing good. I pulled the wicks out of the solution. Maybe I should add some straight water to the top to try and flush out a bit

I’m not actually in Chicago, northwest suburbs but Chicago sounds cooler haha. I had no idea about the nutes until I came to this forum and an admin mentioned that since FFHF is organic soil, no nutes needed for a while. I had been giving them a 1/4 of the dosage, but still. Scared me enough to stop.

I know everywhere I read it said for the vegetative stage that they need 60% humidity. I got all worried about it but my plants did just fine with a humidifier at 35%. For the flowering stage, I pulled the humidifier, and am now in the 20’s for RH. They still seem fine.

I’d just give the affected plants some PH’d tap water. See if they recover. Don’t feel bad though, like I mentioned, I had NO IDEA about the nutes until this forum. Seemed like every youtube video out there, they’re giving them all sorts of stuff. I just thought that was protocol. I’ve made plenty of mistakes along the way and despite that, the plants seem pretty resilient so I hope yours recover ok. Let us know!

Best of luck.

Haha, Chicago is :sunglasses: I’m by Rockford

Yeah, I tried to do my research but if you read enough, you’ll get every different opinion there is :rofl: i grew under a 400w MH, years back, but nothing ever got sick. Now I have a 5x5 tent for 1st time. I’ve grown alot outdoors

I will definitely update you guys. Im going to post again here to answer the questions

Thanks :blush:

  • What strain, Seed bank, or bag seed-- Gelato auto from ILGM

  • Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF – Happy frog in 3 gallon bags using wicks. I’m adding oxygen but don’t know if it’s enough. 1 stone each tub

  • Vessels: Pots, Grow beds, Buckets, Troths-- 3 gallon porous grow bags

  • PH of Water, Solution, runoff (if Applicable)-- unsure of my product to test ph of solutions. The color chart that came with the kit doesn’t match other color charts online. See pics

  • PPM/TDS or EC of nutrient solution if applicable-- no idea

  • Indoor or Outdoor-- indoor 5x5 tent

  • Light system-- 1000w MH

  • Temps; Day, Night-- Average 77°f

  • Humidity; Day, Night-- Average 30%

  • Ventilation system; Yes, No, Size-- Yes. Ventilated hood and interior. 2 6" inline fans. Each move 390cfm at full speed but I run them a little quieter

  • AC, Humidifier, De-humidifier,-- No

  • Co2; Yes, No-- Noph-scale_orig

Soooo, according to the kit, my solution ph was alkaline so I reduced it to 6.5… but if you look at the other chart, im between 3 and 4…

I’ve only adjusted the sick plant but the wicks are out of the solution

I have a digital reader for soil ordered, but not sure what’s best and cost effective for water

Do you have a link? Does it say specifically for soil? Here’s the kit I got:

The pros on here might say different but I believe you’ll want to test the PH/TDS of the water before it goes into the soil, and then check the PH/TDS of the run off, after watering.

I have the ph tester in your link but not the TDS (is that same as ppm?) My tap water is a bit high but when I adjust it (just water, no nutrients) it get a little cloudy in the reservoir and foams up around my air stone. Im going to the other meter but am worried about having to filter the water. Thats alot of water for 5 plants once they get going im thinking :laughing:

That first test kit was manual compare the colors

Here’s where I’m at. Gelato is slowly improving with just water

Yes, and it has a few settings on it.

Mine kinda looks cloudy at first too. However, after a few mins, it seems to clear up. Does yours? You really shouldn’t have to filter the water. Maybe if you’re using pond water or something haha.

They look good minus the last one of course. I want to say just trim the bottom two leaves. They won’t recover. The important thing on this plant is that new growth is healthy. Which from what I can tell, it is.

No, my water is still cloudy… who knows. Im about 1000 yards from the pump/reservoir for our city. Seems like we can tell when they stir the tank. Maybe there’s a chemical reaction with the ph down and some stupid chemical they add. I already filter for coffee and some cooking water. I need a whole house filter but don’t have the money right now. Im just gonna let it go as I think.

Do you aerate your solution?

What kind/brand of nutrients do you use. Im just using miracle plus a bloom fertilizer that has to be used on top of my base fertilizer.

Im currently using miracle grow 24 8 16, but im going to switch to 18 18 21 a couple weeks before flowers and add the bloom booster 1 34 32 on top for flowering until i flush it at the end
