Former Problems or New Ones

So basically my ph meter broke 5 weeks ago 3 weeks ago i replaced it with a new better one. Im not sure at this point if things are getting better but for the most part it doesnt seem like it getting worse

i just transitioned into flower i will be giving updates as i check

Sure looked like a heat issue to me.

Also Mg and K.

You running soil or hydro?

hydro its absolutely NOT heat issues. Actually my room temps get to low more than to high 65-75. my ph had gotten screwed over until i realized my meter was fried. the 1k HPS light sits around 1ft away from the tops of the plants (air cooled). Hmm ive been thinking Mg and sulfer. so u think they need more k?

Yes mate More K would be good, maybe a bloom booster?
