Use fox farm soil

i have jack herer auto and Skittle auto in ocean forest soil. my skittle are showing calcium deficiency they are only 2 weeks old. what should I do

Start cal-mag, I use a FF soil mixture and always start cal-mag early on. :+1:


Any suggestions on what cal mag to get, and how much to get 1 plant (ww auto) for now

I currently us General Hydroponic CalMagic. I am satisfied with it and it only adds 1% N. I am running low and need to get some more.

That works. Use what your used to

2ml per gallon
