I can throw in a tip for guerrilla grows : save your banana skins, dry and powder them, then just sprinkle generously on ground each chance given ;-) .

To me it looks more like a potassium deficiency. A magnesium deficiency would affect the whole leaf, not just the edges.

Looks like a magnesium deficiency. Have you been using a cal mag supplement. If not it may be wise to. Also it could be a incorrect ph stopping your plant absorbing magnesium.

Few leaves of my plants are getting these pattern with dots. I optimistically hope that it is just part of the aging of the leaves. Other leaves became yellow and fell also (maybe worth to mention). Is it normal? Thanks

Light markings on new leaves.I'm on day 9 from putting the seed into a paper towel. Day 7 from putting it in soil. Day 5/6 from seedling sprouting. Looking closely there are markings on the leaves, what are they and should I be worried? Is the little girl stressed? Also is developing slowly?

Slow Growth and Leaf Issues Transplanted outdoors over a week ago and have noticed slow growth and new leaves have little holes and yellow spots on them. I've checked for bugs but can't see anything. Could this be nutrient-related? Or shock? Ph levels? Too rich soil? Any help is appreciated. Cheers.

To defoilate or not to defoilate.. that is the question!I've always heard that you shouldn't "defoilate" auto flower cannabis, especially if they're a sativa to boot. With that being said, (looking at my pics for reference) should I do more defoliation? Would doing so really increase my yield significantly? Thanks

There is something wrong with my plants but I'm not sure, I hope it's nutrient burn, iun whiuchn case I will flush with PH water, but it could be nutrient deficiency, what I am most concerned about is that this is root rot. What do you think it is and what should should i do?
