coco deficiencies in bottom/medium canopy leaves
NobodysBudsanswered grow question 5 years ago
looks like you nee dmore nitrogen from the fade. the brown could be related to poorly prepared coco, if oyu got the cheap stuff, or it could just be too low of nutes.
feed more, i'd guess... could wait a sec and make sure that's the case if it detiorates quickly with a couple water-only feeds. won't take long in coco for deficiences to get worse, but toxicities still take a while to reverse course.
if you've been light on nutes, i'd fertilize more often than you have so far. coco needs fertilizer every feed... rarely a water only dose.

Burned upper leaf edgesHi!
Dark spots appeared on some upper leaves overnight.
I don't think this is the cause, but I did a pretty heavy defoliation the day before.
the spots only affects leaf margins and makes the tips curl up. The spots are brown, burned and slightly purplish.
what could this be?Week 5

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

dark, curled downwards and brown fan leavesWhy are the fan leaves dark, curled downwards and showing brown marks originating from the edges?

Why leaves brown? (urgent)Some leaves turn brown as in the photo. Leaves in the middle turn brown first, then bottom leaves. Now I try making larger lamp-to-plant distance and feeding less nutrients, but no good sign appears. Other conditions are stated in my diary. Why do you think it is?Week 7

leaves dry and curling upGelato canopy leaves continue to dry and canoeing up. I've backed off the lights, changed the air circulation, and gave only water in the last week, but the situation is just getting worse. Canopy buds are not growing and trichomes production is much higher in the lower branches4 years ago
