I trimmed the off the large fan leaves a few days before i started flowering. Then this started. The top leaves look tired and the are turning light green. I started with coco. I am using clay pellets now. Please Help!!!!
What is your PH? I've seen PH issues cause this. It could also be an iron/zinc deficiency or possibly sulfur. For sulfur you can try adding some Epsom salts to your solution. First though, make sure your PH is on balance. Hydro requires between 5.5 and 6.5 Sent from my ONEPLUS A6003 using Tapatalk
Do you use plain ol tap water? What is your waters starting ppm? Sent from my ONEPLUS A6003 using Tapatalk
Since your yellowing appears to start in the middle of the leaf and moves out toward the tips, I'm leaning on an Iron deficiency. I've used this for iron issues. Just be sure not to overdose, as I think that's what I did. Too much iron will cause problems too. Sent from my ONEPLUS A6003 using Tapatalk
Guess the link didn't work. Search Amazon for Liquinox 3032 Iron Zinc Chelated Solution Sent from my ONEPLUS A6003 using Tapatalk
