Hi! You probably want to check on the pH of your drain at first.. :) If it's too low, there could be lots of deficiency signs but caused by low pH. All the best!!

When mine did that, it was cal-mag, but mine were hydroponic

Deficiency/Light Stress IssuesWhat else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Yellow/Brown/Spotted/Crispy Lower LeavesWhat is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

Maui Waui CA deficiency?Can anyone confirm or guess at the kind of deficiency my plant is having?
I am not sure if "hard water" (instead of RO so far) is the right answer or if I need some special sauce...
Thank you!

Leaf damage/discolourationThe yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?
