answered grow question 6y ago
Well my guess is it’s pretty much the oldest leaf on your plant and that is why it yellowed on you! This is why we do defoliation! As your plant grows new leaves these big old leaves die out! 🍀👍 you got nothing to worry about! 💯🤟

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.

Yellow leaf tips and edges
Yellow leaf tips and margins… what do you think? Nute burn? Light stress? Cold stress? Will this eventually resolve if I leave it alone and let it work itself out? (Which is what I’m inclined to do) Should I flush my plants or try some other intervention?

Bottom leaves lifeless and yellow
Hi! My plants are in their 2nd week of flowering and some of the leaves at the bottom of the plant (very few in the middle) are starting to turn yellow and they look kind of lifeless. It's very dense in the tent so maybe they don't have enough light? or lack of nutrients ?

Should I cut off yellow leaves?
Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

Magnesium nutrient lock out, triggered by too much potassium ?
