Leaves bright green
So I have ruled out the fact that this is not a ph problem, have been properly watering at a consistent ph of 6.5, tested the run off today and it's at a pH of 6.4, also there is purple stems and the main stock has purple running through it as well?!?! Is this lack of pk? ca/mg?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

Natural or Problem?
Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.
Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?
