Chocolate haze vs Cereal Milk

Not one but 2 flat stems now the cerial milk has one.... royal queen really like shit genetics...

managed to raise my temps from 18 to 22C and the plants started to give out some smell nothing much but it smells like weed. got a hint of citrus but could have been my imagination went away as soon as i felt it...
started lowering nutes again tap water is 175 and they say they are eating too much at 230.thats what 50ppms of nutes.... but they are still hungry for magnesium soo i give them water and 1g of magnesium almost every day

noticed these top leafs all had purple in them after reading a little bit it could be calcium deficency got some leafs with spotting as well soo maybe today i am gonna add some calcium or maybe its phosporus i am gonna have to double check it when lights turn on
but could allsoo all be from low ph i have had 5.5 and 4.8 a few days kept fighting with too low ph.(didnt want to lower nutes even more but i guess i have to )

soo i basicly gave her only water and still the ppms are rising soo i have decided this strain is not hydro frendly or at least my nutes frendly....
and today i noticed she looked different couldnt figure it out until i noticed the whole plant decided the buds are too heavy for her and just bent.
one small branch broke i did i quick fix and tied a few branches but i dont have any more to tie rest.it would be cool to make net but maybe its too late now.

Ppms keep rising but no signs of nute deficency yet.just some purple stems from before but plant is growing.... we are now at 200ppms.first time in a few weeks that the ph didnt go to 7 after just 1 day
