DOnt get fancy.Use tap water and adjust to 6.0-6.75 phUse 2 bubblers on your resuse 1/4 nutes after they reach about 2 inches and or have multiple leaves.After they are 3-4 inches goto full nutes.do not use anything fancy. If your set came with nutes- use em! Stealth Hydro nutes are decent actually.If you have the money try nutes made for hydro. ( i like tecnafloras BC nutes )Use as many lumens as possible. Add lights when you can.Wait until they are fully ready to harvest!
