For Christs sake when you got such wonderful looking plants like that why are you giving them chemicals? There is no place for the excess chemicals and for the plant to detoxify itself in that stage of flowering....yes totally normal to have yellowed lower leaves and later on even up the ladder some but that really looks like chem burn because it's not a uniform yellowing associated with aging leaves more like a ZAP SPLASH of some kind of toxins...those plants have all the stuff they need to make real nice fat think buds WITH PLAIN WATER! (and it will taste good too...) let the plant do whats it's supposed to do..whoever herd of something in nature that comes out of the sky and dumps a bunch of chemicals on natures wonderful work...ahh...becasue..uh...someone said so??? NO NO NO -- plants store up in them all the nutrients they need any excess is eliminated through the leaves through respiration .. leaf mass is reduced during flowering hence less plant bio mass to process chemicals -- bloom boosters are great I use them myself but what I see a lot of here is OVER FERTILIZING -- I am no angel I like to push my plants also we all do but when you them buds -- leave em alone and go have some suds -forgettably --
For the love of god!!!! Can you remind me why agriculture, the world over, uses ferts and nutes. Why base elements are ploughed into our fields year after year. Oh yes, I neary forgot. To strengthen and increase crop yield.
Give ya tree huggin tripe a rest, we all know they will grow with just plain water but we all want them to flurish, excell and get us mashed night after night. Go have a cup of elderflower tea and chill out.
