Burnt tips
Robertsanswered grow question 2 years ago
Burnt straight tips is potassium deficiency. Burnt tips that curl up is nute burn. Very commonly miss diagnosed. Your plant wanted more to produce denser, more potent buds when they told you to back off. Need to be careful on answer you choose. Lots of wrong information that is incorrect from people using Google, and not knowing how to read leaves. All plants even autos need rest. I run a 20/4 on mine. Good luck. 🌱

Necrotic spotsThe last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!5 years ago

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??5 years ago
