what do you guys think?

I am on my second grow with cheese plants in coco, i have two 600w lights over 15 plants. i will be using canna a and b during veg and during 12/12 i will still be using the canna a and b, headmasta & hammerhead what do u think? any advice appriciated.

Thats a nice set up brother, are you looking for recommendations for nutes? I would recommend Carbo load from advanced. They will fatten your palnts like hell and wont ever burn them or fuc w/ph.

Thanks bro, what do u think of the headmasta & hammerhead? my ph is always 5.8

After becoming friends with my local hydro shop owner I only use Advanced Nutes, srry bro I have no experence with ur stuff. Advanced is ph balanced/ I never have to worry about the ph in my soil.

no worries mate, any advice for yield?

Carbo load!! I cant say that enough. it will mix with the stuff you have now and only costs 30$ us / its like feeding your plants fast food ( they get fat! )
