My girls started yellowing from bottom up today. They were green today with maybe a couple bottom leaves barely yellow this morning. Looks like maybe some clawing on a couple leaves.
I fed them this morning as they were droopy asking for water with Advanced Nutrients and Cal-Mag. I've been alternating straight water and nutrients. Is this nitrogen toxicity or something else? The leaves don't look dark green enough for toxicity. Thanks in advance for any and all help and suggestions!
Grow info: Fox Farms Ocean Forest soil (but it's been a few months so definitely out of nutrients), photos that are in flowering... I think almost week 3 of flowering. No major swings in temps or humidity.
