Before trying to diagnose ANY sort of problem with your plants, you should make sure your fundamental growing elements are up to par. Is your water legit (proper pH, no heavy metals, etc.)?, what's the pH of your soil?, how far are your lights from your plants?, all the basic things. Once you're sure all of these things are correct, then you can start trying to figure out what (if anything) is actually wrong with your plants. All of these things can mask or mimic problems with your plant, making it difficult to diagnose.

I was in a similar boat as you, and the biggest wad of advice I can give you is to get a pH tester of some kind. I was under the impression that boiling, filtering, and evaporating my tap water would suffice for a water supply... but I was awfully wrong. After reluctantly investing in a pH tester, I found that the pH of my water was alarmingly alkali. After investing in store-bought gallon jugs of distilled water, my plants are doing MUCH better.
fuehrer Reviewed by fuehrer on . Is this pH problems? these guys are 5 days old they are NLxBB one is slightly yellow and the other has these yellow spots on the bottom leaves. Im thinking its pH because on the smaller plant the leaves curl up a tad and i read that meant pH too high but i wanted to check..:stoned: Rating: 5
