Hard to see under lights, mag def has yellowin leaves and brown spots, so do a cple other things unfortunately. Have you fed it for mag? I'm gonna say from the off I'm not sure what it is but could probably help you narrow it down, or eliminate some things. 17c is about as low as it should go, I don't like droppin below 19c. Erm, what's ya water like, hard or soft? If it's hard it's full of calcium so if you've been constantly been giving calmag then it could be salt build up. Could be hungry for P K if you've not added any boosters.

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 ?

Yellow marks in leaf center and weird King Kush?There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?4y ago
