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 ?4 years ago

Magnesium deficiency?I think I may have an early deficiency of magnesium? I'm totally guessing here. Not much experience. Seems to slowly be getting more pronounced.
First water since transplant to FFOF was only pure RO. Thinking maybe I should added cal-mag?Week 3
