Vitals
Total newbie been reading everything I can
4x4 tent
Mars hydro 1200
6 inch fans and exhaust
soil and trio
Cal Mag plus
2 Chem City Blues
2 West Coast OG Kush
Popped 3/10
1 0f each looked great from the start other ones were slow but are catching up. So I think I have a cal mag deficiency but I have been using cal mag plus. I did not start it till about 4 watering ago. First 2 half doses then 3/4 doses. Every other water. Last watering 2 days ago straight ph'ed water. Am getting brown rust colored spots. Starting on the top of the Chem City and the bottom of the OG. Really at a loss.

I agree with you, sure looks like a calmag def to me. Those bottom leaves may be a bit of nute splash? In any case, autos grown under led eat a ton of calmag, I ran into it my first 2 grows, I'd try cranking it up to a full size feed of calmag ASAP. The effected leaves will still look bad, won't heal, but it should cease the spread. Perhaps @Waira and other more experienced growers will chime in soon. You're in the right place for help.

I am seeing some clawing leaves there, coupled with brown or yellowing tips. Hmmm. Perhaps dial back your feeding. I am not saying flush because its not necessary, just enough to leach some salts and nitrogen. If you use the Ocean Forest, you must account for the high nutrient concentration and balance with feeding. Fox farm, has a fine line between excellent and overdone. If the plants metabolism doesn't require more nutrients, the excess builds in the leaf tips and they're toast.

I don't know that you have a calcium issue. Your in flower now and your leaves are nice and green so you have probably been feeding grow big. What about big bloom? I believe that is the one with the P,K and it looks like that's what you need.

Where are you at in your nutrient usage? And do you water to run off?

I think Big Bloom will sort you out, be careful with the tiger bloom it does have nitrogen in it and you kind of have to watch that.
