Ive always used CANNA nuits ie. hydro vega parts a+b, hydro florez parts a+b, rhizotonic, zym, and boost. You can check out my pics i have all my hydroponic nuitss listed there, these nuits will give great results oh and if you want your plants to pack an extra punch buy CHA-CHING!! this yellow tub of powder will really sort out your cola's the buds will be dripping in THC just make sure you flush for 2 weeks before harvesting with PH balanced water only! this will give you a potent but ultra smooth smoke
ps leave some comments on my pics if you like, my bloody camera wont load new pics and ive got quite a few more recent fuller pics and am now a week away from starting the flowering phase, I will keep all my pics so when i can finally upload, i will! good luck HYDRO is defo. the way forward, plants grow way bigger this way, write back when you can from stelthy
