Hey Farside, greetings. What size buckets are those? 5 gal? How much medium are the plants in? I am contemplating a SIP grow but I have to get my head around logistics and DIY still. I see mention by you of running autos in a SIP setup. Have you done it yet?
Sorry. I've been MIA. Wife decided to share her bronchitis with me the day before Thanksgiving. Then it tore through my workplace and I was recently promoted so guess who got to work while sick and all my other employees took off. Yep, me. Had a 24hour shift I had to do last Thursday.
These are 5 gallon buckets with a 1 gallon reservoir and 4 gallons of Pro Mix.
Despite adding plenty of Cal-Mag and Potassium to supplement the Osmocote, I still can't get them back to green. The last 2 days I've went ahead and fed them the full compliment of FN Fertilizer ™ (FN Silica, FN Micros, FN A, and FN B). We'll see if they were just running out of Osmocote.
