Dutch Passion Auto Extreme grow

Subbed on this.

If you are having nutrient burn issues, have you tried flushing some of it out on a watering? Also I have never had dolomite lime burn plants, are you using hydrated lime? Hydrated lime must be used in very small amounts or it will burn your plants. If you are using dolomite lime then I would suspect the worm castings. Maybe next time use the hot soil on the bottom of your containers and lighter soil on the top, that way roots can grow into the hot mix when they are older kind of like super soil.
 
I doubt it's the lime causing the burn. FFOF is pretty hot on its own and can cause issues with young autos, and then with 5lbs of worm castings added, I'm surprised that both plants aren't hurting. The good thing is that if they can survive their youth without getting too stunted, they'll get fat and happy on all those nutes. Subbing up for this one and I've been considering an Auto Extreme grow myself. "Munch..munch..munch

I've been doing some checking, and General Hydroponics CaliMagic is the only cal mag with nothing else in it,so also ad sulfur

I just checked GH website and climatic has 1% nitrogen in it half as much as other products, General Organics CaMg+ has no nitrogen, neither product has sulfur in it. But if you wanted sulfur Epsom salts or Magnesium Sulphate would work great.
 
dolomite lime. I think it was more of a lockout caused by cal-mag I added.

What cal mag product are you using? Why would it lockout the other nutrients? What was the PH? I think they are just burning from the hot soil and adding cal mag compounded the problem. Next grow I would omit the castings, and the vermiculite it isnt needed and Ive seen it cause over watering/root rot issues. Just the blend of Perlite, FFOF, FFLW, and 2 teaspoons per gallon of dolomite lime.

I used a very similar mix to grow these!
