Deficiency
GrnMtnGanjastarted grow question 3 years ago
Does this look like a magnesium deficiency? Getting some yellowing around the edges of some lower fan leaves.

This is burning from feeding too much or too often,.....or both.
Acapulco Gold being a sativa requires much less feeding, especially nitrogen, than your typical indica or hybrid.
Cutting your feeding in half should stop this from getting too much worse.

I had the same with my Lemon Haze 3 years ago. It was a ph problem (too high) which caused lockout troubles. The nutrients were in the soil but because of the ph value the roots weren't able to take them up. U are growing in hydroponic and i have no experience with that but a "flush" or change in water for hydro to the lower the ph would be my guess. After that a slow build up for nutrients and it will be fine.

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

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

2 Yellowing Fan LeavesI have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges.
It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant.
From research, it could be the bump in nutes or water issue.
Any ideas?5 years ago

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅
Same issue still applies for now.
I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍
