Please help getting past frustrated

I don't know what s going on ive been growing successfully for a year or two now with Good results, so Idk what I'm doing wrong now or what to do about it, my lat grow I went from supersoil to Ffof with Humboldt natural line the grow, bloom ,mycomadness, honey,deuces deuce, and equilibrium (ca mag) and a little dolomite I burned the hell out of the last plants so I learned that lesson and this go around I decided to take it easier and measure more carefully, so I went withrough happy frog and perlite about a 50/50 mix in 2 gal smart pots , started nutrients at 4 weeks old at 1/2 strength following the schedule using everything but the equilibrium and flavorful until the last two water cycles , (week 4 into 5 of flowering full strength on all nutrients ) I water with distilled water every 3rd day with nutrients and give plain distilled water every third watering to make a sure I wasn't building up too many nutrients in the soil scared to burn them again ,
400 watt hps Temps and humidity are 75 and 40ish
I'm sorry it's just jumbled info but you know what im using so heres the ladies ....wtf is wrong

Side note , I've been using the same smart pots for 4 grows now and have always labeled them with a small strip of white duct tape on the outside of the pots , didn't seem to be a problem but now I'm wondering if my problem is something built up in the fabric of the pots thats causing problems or am I overthiking that?

What's wrong?

Pics up sorry

Bump for any help

looks like cal mag deficiency

Anyone else?

That does look like a cal-mag def/lockout. Whats your ppms. What is you ph at? In my experience with FFOF or peat based mediums and heavy nutes (you said you were going full strength) the ph tends to dive about midway through flowering so you may have a salty acidic medium. Cal def is one of those things needs to be identified and addressed early too.

Thank you for the rely I'm going to try some more calmag and hope they aren't locked out but I believe your right they are I'm definetly considering dolomite lime and oyster shell flour with my next run to try to stabilize the ph
