Hi weedkiller.
Thank u for choose Chaze, u'll love it...
I think that ur feeding program should me appropiate, but just a very important data that u forgot is that it is a Super Auto and this mean to get very tall plants and not ready in 10 weeks, but 12/14...
The Super Autos are very quick and strong growing, very good results in outdoor grows, indoor too when trying to get them short.
Super Auto Chaze and other Super Autos do provide over than 1oo gr per plant in outdoor conditions, not indoor and less if u plan to grow 12 of them in a such small place.
So my personal advise is to grow only half of them, so max 6, of ur Chaze into ur 2 m tent, or 4 maybe could be the best and try to really open ur plants at the same time they are growing.
use the bigest cubes u can find, the 20 cm ones must be the pèrfect one even bigger to support the weight of the plantsand help the best as u can ur plants ataching them.
I did never tried Super autos in Nft, but i did with my Jet 47, and the pants get very tall, over 1,20 m so i can imagine with Chaze Super Auto...
I really want that ur grow get ok and the most perfect as it can be,so that's why don't doubt toask me what u want at anytime...
Hope this will be ok, take care
