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

Leaf tips are browningCiao tutti,
What is going on with these leaf tips?
It’s the third day of their Flush & It can’t be NutBurn, or the color of tips doesnt look like NutDef!
Is the light stress?
If this de-coloring continues, will it effect the buds & final yield?
ThanksWeek 12

Cal-mag issue that won't go awayI keep getting a cal-mag deficiency. I have been using 1ml per liter of water - 4ml roughly per gallon. It is only 1 plant, the same which has had the same cal-mag issue since early veg.
I include cal-mag every watering and nutrient feed day.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown.
This starts at the tips of the large lower leaves and spreads quickly to the whole leaf.
Also modest edge curl.
