If you want a 1-bag solution to do a lot of gallons, has anyone looked at Grow More Mendocino Foliage Pro, Rockwool, and Bloom?

I have had excellent results with them. I did have to let the solution sit overnight or put in a stir pump to get all of the solids to dissolve. Still good stuff.

Anyone using Jack’s 3-2-1 with multiple high ppfd LED’s? 1st I had mag defics so upped basically to 3-2-2 and now I’m getting textbook calcium defics. WTF? I’m at near 1000ppm. No burn but I’m still getting the splotch. I have never seen anything like this before in all my years. Anyone?

What are you growing in? I maxed out in coco at 2.0 EC.
In RDWC, I maxed out at 1.2 EC. This is using stock 3-2-1.

For an 8 week strain, I always hit the max EC value week 6. Week 7, I cut out CalNit. Week 8 is just water, maybe add .5 EC Potassium Sulfate if I'm feeling fancy.

I run a 4” rockwool cube atop of 4-5” of mini rw croutons in a 3 gal smart pot. Ph is 5.7-6.1 fluctuations of .1-.3 daily. Things are looking better after a serious defol.
