Hi I'm having a problem with an Ultimate Indica plant that I'm growing, and I was hoping somebody could help me figure out what the issue is. I have attached several pictures of the plant with the issue. I'm growing 11 addition plants that are not having any issues at all. All 12 were all started from seed. 5 Ultimate Indica, 3 Durban Poison, 1 Burmese Kush x Strawberry, and 3 Supreme Hash Plant. I keep the ph at 6.2. I use de-chlorinated/sediment free water. Nutrients I have used with these plants so far include General Hydroponics CalMag, Orca, Fox Farm Big Bloom, Fox Farm Grow Big, Fox Farm Kangaroots, Fox Farm Boomerang, Fox Farm Flower Kiss, and Fox Farm Microbe Brew. I use Fox Farm Ocean Forest soil. Can anybody tell me what this is? I'm assuming it's an overdose but I don't know what type. It's good to know that this specific plant is the only one suffering at all, so that I don't clone it and try to keep growing it.
I wouldn't worry about it at all really, it's only on a few older leaves and new growth looks good I would ignore it unless you start to see it get worse
Well my temps stay in the 70's, sometimes it creeps into the low 80's. Humidity is low, the only way the plants and room receive humidity is when I water, or foliar spray...
