Top leaves turn dark and curl - What can I do?
Dragosani666started grow question 2y ago
I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

That is due to temperatures dropping to sub 68F or genetics. Fall/autumn colors just as you see in tres outside.
So, this wasn't caused by nutrient issues. If you had any other symptoms do consider those, but otherwise resume normal fertigation before it runs out of building blocks for growth.
no worries, i've seen significantly more decimated canopies on plants that continue to develop and finish their buds. Any negative impact is probably imperceivable if you get it back on track.

Looking at previous weeks in diary, you had a N-deficiency creeping in and some burnt tips. Definitely need a little more N than you provided before. too many things cause tip-burn to be confident about the cause. Any leaf symptom chart can verify that. Would need more infor to eliminate possibilities.

The tip curling .. tough to know without seeing the progression if that's something else coinciding.
