purple stems and yellowing

Giving less nutes then suggested is always the best,it looks like nite burn,try flushing her with plain water for a couple days,see what happens ,with lunch she'll straighten right out,if if says two teaspoons of nutes,use one and a half!happy growing!

Probably something like nitrogen excess.

I think she is trying to tell you that she is getting too much nutrients. Just give her plain water for next few waterings. Then gently restart with light doses of nutrients.

Why are you using such high levels of nutrients? If your diary is correct you are using 9.22 tsp/gal of tiger bloom.......recommended dosage is 1-3 tsp/gal, then you got 3 tsp/gal of cal-mag, thats 3 times as much as you should be using. Once again i'm going by the amounts in your diary, if they are indeed correct, then you need to lower everything to what the manufacturer recommends. Happy growing.
