Don’t up the mail msg, they only need ml to the gallon you give them. That looks like heat stress from your lights. I would raise your lights up a little bit higher a few inches or turn the percentage back a few percent if it’s a dimmable. I had that happen once with a Mars hydro a 80 percent and I fixed itself when I dimmed it back to 65. Good luck

Wrong pH for three weeksI realized I was feeding my plant tap water with a pH of 8-8,5 for a good three weeks. I just flushed my autoflowers, three times the amount of soil with water corrected to 6-6.5. Will that solve this issue I was having (nutes lockout I think)? Did I fix my soil pH by doing this?

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

Gorilla Cookie Week 8I will try to keep this short, but my Gorilla Cookie autoflower has some problems. The tips look like they are burnt or dying. I use living soil, so I didn't really give my plants any nutrients except worm humus a long time ago and BioBizz Top-Max yesterday 3ml/L. See my diary

Infected Leaves. To remove part of the leaf or whole leaf?I had had pests and disease issues my second grow of Autoflowers. I believe it was hemp russet mites which spread disease on parts of many of my leaves. Would it be alright to remove only the part of the leaf that was infected or to remove the entire leaf?Leaves.

Lack of water or its something else.Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄
