The GSC seems to have a natural tendency to spread out and so far no need to LST. Girls are just starting their stretch. Otherwise all good. Had some brown spots, applied CalMg and all fixed up.
My formula for my 50l tank is 30ml=.3 EC. This ratio works great. I use the 3-2-1 proportions to the 30ml dose. Ie right now I’m doing an 8x30 dose to get me to 2.0 EC. I add a double dose 60ml daily these days as the girls are drinking like sailors.
