What are the N-P-K levels? - You do know there are 3 stages in the flower stage:
early flower - 1-2 weeks with higher “K” levels than "P’
middle flower weeks 3-4 with higher P levels than " K"
late flower weeks 5-7 use higher K levels than P
for better information NPK levels of your nutrients - with out knowing stop using Bio-grow (just for vegation stage) consider bio-bloom in early flower and Top max for late flower and (possibly for early flower) (unknow NPK) If you have a root stimluator use it - if none consider getting some for next grow- it will increase your yields by at least 30% + ( is used correctly) How far are you in flower stage ? doing things OK - just need a littler 'twik" - keep us posted
