Leaves turning brown/purple
tiasmaaastarted grow question 3y ago
The leaves on one plant started to turn a little pale, and with brown/purple spots. And on the other plant it starts to turn more yellow, probably Nitrogen deficiency for this one.
What do you guys think ?

They look a little underfed and or the ph may be off a little. If they were overfed, alot of your pistols would have browned already.
