Calcium Def? Potassium Maybe? Help!

[KaptainKush]

Came back to my plants today and noticed an abundance amount of leaves yellowing,dying and "rust" spotting. Anyone know what this may be? I havent given them anything except recharge and a little bit of silica (once). They're potted in 3.6 gallon pots filled with happy frog. I tried to run this grow without using much nutes in the veg state becausw i ran into N tox last grow. But apparently that was a bad idea i believe. What do yall think?

They look real hungry... not a soil grower though so I can't really give you any advice

That was my first initial thought as well.

First start with pH. Most issues can be fixed with a simple pH adjustment without dumping a bunch of nutes at it. First you have to understand what the real problem is. Second you might want to check for bugs in the process take a close look for root aphids. IMO I'd clean up the floor of your tent, cleanliness is key man can't stress that enough. I always ran calmag when in Happy Frog. What's your PH?

 

[KaptainKush]

My ph out the faucet is 7.5. I use ph down and get it around 6.3-6.7..

I like to swing between 6.2 - 6.5 in soil. I would feed and add Cal mag and stay around 6.5 for a bit. pH after your add your Nutes. Get more than recharge to feed.

I use GH trio nutes, recharge, armor si and mammoth P.

Yeah use your GH nutes stay at 6.5 add Cal mag and you'll get back on track.
