Looks like there’s yellowing in between the veins of the leaf to me. That or the lights making it look that way. Anyhow that’d be magnesium deficien

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

I am getting leaf curling and yellowing on my 3-week-old Hulkberry plant. I suspect nutrient burn, even though I am using what was recommended by my local grow shop and also RQS's website. I have reverted to water only and raised the light higher. Anything else?

PLEASE HELP ME, my frozen black cherry is drying, what could I do?
It’s in the early third week of the flowering phase, but I don’t know some lower branches are drying out day by day, the first three photos shows what I mean, the last one is of the higher branches. Haven't watered for a day, but I don't think its a overwatering problem.
