Yellow leaves and spots

herbalistsswordstarted grow question 5y ago

Noticed some leaves growing yellow at the bottom of the plant, a few days ago, added biobizz bloom as I hadn't used any fertiliser yet. Today I noticed the spots on 1 of the leaves, veins in the middle have what looks like rust. Any ideas?

Hi, your girl is fine, looks healty and with the right tone of green. Is a natural process at this stage to lose bottom leaves. Also your feeding schedule is right, nothing to worry about IMO. Be patient and balanced 🤞

Yellowing on GT and clawing on CB I'm seeing an issue with Ghost Toof. The lower leaves are burning it seems. It looks like it could be a K(Potassium) issue, or possibly nutrient burn. Also, Chem Bear seems to claw quite a bit. I don't think I'm overwatering... so maybe a Nitrogen issue?
