How much chemical should I use when Firing up the hydro tank. I had It in storage for awhile. Now Im back In buisness. I get stoned alot so I forgot what I did to get started last time. I got the Ph right at about 5.5. Lights on 24/7 I put a few tbs of bat Guano base fertilizer. With some hard water softner. Then I added the regular 3 bottle sys. Base-grow-flower. IN a 2/2/1 set-up. I already have them set up in rockwool. And they are floating in water/chemical 3 diff times in a 24 hour period. AM I fogetting anything????? Im worried about how easy It is to fuck your plants up with too much chemical. I have fucked up my share of plants, Suggestions On chemical Usage help? BTW my hyfro kit holds about 10 gallons of water. all help appreciated.
