Yellowing leaves
I’ve been using Fox Farms Big Grow every other watering at a ph of 6. All other waterings have been tap water at a ph of 7.
Using a mix of mostly alpaca fertilizer in a 15 gal fabric pot. It’s been hot lately, high 80s.
Seems to be only the lower leaves yellowing so far.
Is this is due to nutrient deficiency or maybe under watering?
Thanks!
