It's great stuff I would buy a 1kg tub as an investment but little worried it could go bad over time, I will grab a 8oz one soon, I usually put a full scoop to every 10L, I used to use it ever watering but cost me a fortune with 8 plants in 20L pots.
I can only think of the scrog technique to get the most yield, when I do scrog though I plan to flip them when there around an inch through the screen so once stretch happens I could then get 10-12" stems or full colas and plus the wall scrog with loads of over hangers feeding on the left over light, even if I do get a little larf or popcorn buds I will just turn them into food.
is there anything I can buy apart from great white I can add to help with the veg stage?
I have lowered the light to around 6" from the top of the plants so hopefully that will keep the nodes tight for a compact plant then I will top them.
There currently still only getting water with a touch of calcium, I added 2ml of Plant Magic Magne Cal+ to 5L, I plan to add Advanced Nutrients Sensi A&B, House & Garden Roots Excelurator and Calcium to there next watering.
I don't plan to water coco everyday neither, I will in flower but I really don't want to flood my plants so maybe every other day which in veg isn't really that bad, once they start showing signs of needing more then I will go up in waterings.
