Reoccurring issues

Hey all, I’ve been experiencing a reoccurring problem for my last 2 runs of OG kush and it’s staring to happen again on my current room.
Basically around the middle of week 2, leaves start going pale green, mainly on the top part of the plant. Over time they all turn pale green/yellow, With a bit of Rusting on larger leaves.

A little about my grow, I use a 2 part flower fertilizer. Adding Cal mag@ 5ml per gal to every water. I thought that maybe I was lacking cal mag? I keep my ppm from 900-1200 In the first 3 weeks and ph between 6.3-6.5. I grow in 2 gal pots using standard pro mix.

let me know if I can provide any further info.

cheers

pots looks small. you might be giving too much fert in relation to pot size and way too much calmag.
transplant into large containers like 10 gallons of ocean forest soil, don't give anything else, just water when dry. ocean forest is loaded with nutrients and will do you right. trust the soil. it's okay to mix pro mix and ocean forest. just pull plants out and put them into ocean forest soil.

seems it could go either way! what are those little white dots though

Simple,peat is an inert medium, treat it as such.Think coco,water to 10-20% runoff every 1-2 days.Dont let it dry out or your nutes just go to salt.
Hang on ill find some other threads where I got this from.

I have some moms in promix amended with compost ,they were not looking good.The last 10 days ive been watering it like coco. .1ec ph 6.5 They look awesome now.

It isn't calmag def, not when the grower says they give calmag. probably too much of it in this case.
