I have been feeding them an 800 ppm mixture of the following-

Advanced Nutrients:
Mother earth super tea grow
Sensi-Cal Grow
Piranha
Voodoo Juice
B-52
Revive
Barricade
a little carbo load for the beneficials

Cannazym
H&G Roots Excellerator
Liquid Karma

I think that's it. I don't use all of them every time and even though it seems like a lot some are only 1-2 ml per liter. This time I am sticking to a feed-feed-water schedule instead of a feed-feed-feed-feed-feed-flush the shit out of them-feed method

Do you see a Ca deficiency?
