how far along the way into flowering does the bottom leaves usually start turning yellow? does it start half way into week 4?
It varies upon nutrient schedule, genetics... etc. I've had some that yellowed off mid flower, late flower, never yellowed... Your question is far too open ended.
ok. well im using AV 3 part nutes and GH liquid koolbloom. 1000ppm. Gdp strain. going on half way into week 4 now. i see some yellowing on some but dont see it on others.
