Sorry ive not been around the past week or so, ive been mega busy and had intermittant internet. Ive only been updating my coco journal as ive just harvested 3 grows in a row and its so labour intensive. Anyway check out my other journals if you like plant and bud pics
I switch to bloom nutes a day or 2 before flip. It doesnt increase yield but it does finish plants faster 100%. Ive tried so many diff ways to feed and the schedule i have listed on page one of this thread is about as effective as it gets. The schedule is a generic one that will work for anyone providing adequate lighting and airflow are available, however i dont follow it as its written i adjust and tweak it to every grow as they are all different and after a whole you can read the plants and what they want at diff stages, nothing is set in stone and thats why i hate feed charts in general but the are good for beginners. But yes i count flower from the start of 12/12 and switch straight to bloom feed schedule to load up on p/k and the mix i use has enough N there to allow healthy growth while stretching, the main focus is to get the roots really going the first 2 weeks of flower.
I start my plants in 1-2litre pots, i dont bother with air pots or fabric pots at this point as i want my roots to form a nice ball. Then i go from that pot to my final size pot which is anything from 17litre+. In coco its just not necessary to pot up multiple times. When growing indoors you are limited to how much you can hit per m2 and you can achieve that in a short amount of time. i would never veg more than 6 weeks ever indoors as there is no benefit to longer period in my opinion for several reasons which i wont go into now. But id go with your 3 litre starter pots if thats what you have then id go max 4 plants per m2 and 17-25litre pots to finish.
