Need to get Epsom salts so I can test whatnot like better! I gave them some cal mag yesterday. Thank you for making me feel better about the decision!

Like stated, you have a Calcium and Magnesium issue so you need to give a calmag solution at the bottles recommended dosage and because Calcium is so slow to move around the plant you are best foliar feed once only for a quick injection to speed recovery.

Nafy, I grow with the same nutes. I run into this Cal deficiency at times. I feel that this may be from Ca. only being available at either end of the pH(5.5-6.5) range. I try and let my nutes start @5.5 and bump it up during the week to 6.5 at the end of 7-10 days. Cal-Mag will fix this-just add to your regular feeding

honestly i feel it was a PH issue. i got caught up for 2 days, and when i finally had time to check the Res, it was at 4.0... to be safe, i changed the reservoir on both of my plants, with fresh nutes. im starting them at 6.5. for some reason my PH goes down. as the plant eats. or am i crazy?

They don't have pH burn

no.. but having too low of a PH will Lockout my plant... hence cause a Calcium deficiency
Can the deficiencies of calcium or magnesium go further on the leaf as in the loosely looking like rust spots nearer the end of the leaf could dry out and (@ the point of conditions) fall off? As I am experiencing serious leaf damage early. Comp/perlite ph6.6 struggle humidity at 35-45% 3 weeks veg and 27C 80F added mag and leaf curl lessened but worried lime would lower ph to much . I am still padwan and advice would be appreciated

This is the one for hydro!!
This is why I think that it's important to let the pH range from 5.5-6.5 Some nutrients are only bio-available at either end of the pH range so if you keep the pH say at 5.5, Mg and Ca are not accessible by the plant.

What water and nutes are you using?

Indeed it is-he stated in the first post that he's in DWC.

what PPMs is your tap? its possible you have Hard tap water, and you are getting nute locked.

Yes sir, I’m aware, I was backing your post ‘‘tis all.

seems like pretty solid water to me. im not a soil guy, but maybe you could be getting locked out from the nutrients of the soil, or even from your PH.
