im on my first grow and tomorrow will be week 5 of flower and i started growing 3 strains from seed. i am growing lsd, og kush 18, and white berry. the white berry and lsd are 8 week strains and the og is a 9 week strain. i know those are just guidlines and i need to watch trichomes to know when to harvest. anyway i have some advanced nutrients overdrive that i would like to try but it says to use on weeks 5 and 6 or the last 2 weeks of flower and im trying to figure out when would be best to use this. the plants still look like they have alot of budding to do and im not sure how much they will bud over the next couple weeks "weeks 5 and 6" and dont want to use overdrive if its too early, especially on the og since i guess its suppost to take a week longer. i have been using big bud and a couple other things and know im suppost to stop using bigbud when i use overdrive but i cant figure out if i should use overdrive yet or not. can anyone help me to figure out what i should do? here is some pics that may help you decide. thanks. also im growing aero, using the stinkbud system. basically what would you do?
