Cal mag deficiency? White leaves
gottagrowsometimeanswered grow question a year ago
Hmmm..
1stly calmag would be fade in-between the vains (that'll be mag) also few other sym. And cal would show like rust spots in groups.
So not a full calmag.. it looks like mag in a way but also not.
It could be sun burn. I see that plastic tarp? If you had a your plant blocked out for hrs and then it the throws of the roaring hot day took the tarp down. That could be a cause. But it would have to be like going from fully shaded out to 28-30 with mad lux. Just my guess.
You can apply Epsom salt for mag just incase, but again Idt its that.
Good luck

Gottagrowsometime, Thanks for the quick reply! The tarp is just to block the wind and doesn’t put it in shade at all.
The plant was tall and thin when it was young from being indoors and not getting enough light, so maybe it’s not used to full sun all day. The newer leaves that grew while outdoors at the top are nice and green still

Rust spots on leavesHey guys, please help me identify the cause of these rust spots on leaves. Seems to progress in last couple of days(spread).
Might this be a light/heat burn? Or some nute def?
I added CalMag on previous feeding.
Distance to light is 32cm currently.

Calcium deficiency?Hello everyone,
I need your help once again.
I have just spotted some brown/yellow dots on 2 leaves of my plant.
Did some research and looks like Calcium deficiency, but still wanted to ask you.
If that's a Ca deficiency, should I add CalMag next time I feed her?
Thank you ✊

Brown spotsHello everyone,
I have to ask the same question, since that problem is spreading although I give her CalMag.
9 days ago only 2 fan leaves had those brown spots, now almost all of them are affected, especially higher ones.
I wanted to feed her once again and then start flushing

Brown spots on healthy leavesBrown spots developped on seemingly healthy leaves during late vegetative state. She's at ~40 days old. I haven't changed her feeding habit. Soil pH is between 6 and 6.5. Water pH always making sure it is 6.5 before watering. Could it be Cal-Mag deficiency?

Is this Cal/Mag deficiency happening?The taller of the 2 Strawberry Bananas I think is showing some Cal/Mag deficiency so I added 1tsp per gallon when watering. There is only seven leaves exhibiting this on the plant and no other plants have this and everything has been the same for all plants so curious whats up?
