Hi there! I think you may have a slight deficiency in boron and calcium. Try taking a look at this link (https://www.icmag.com/ic/showthread.php?t=153531) and compare your photos, I could very well be wrong :)

it could be a boron deficiency, but I think it's because the light is too close, emitting too much heat or too much light

Brown Spots on Leaves
I've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.

Brown spots
brown spots began to appear, could this be due to watering with PH 6.0, maybe too little and calcium is not absorbed? PH of water with each watering 6.0

Color change.
I always get nervous when the leaves start to change. So my question is, this is natural right? I would guess they are a couple weeks away from finishing?

Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Continuing calmag deficiency
What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Leaf issues with 3 Pineapple Express Autos - is it burn or deficiency?
All 3 plants are having issues to the lower leaves. They are dried and brown blotches, brown edges of the leaves, leaves drooping off and curling down and brown. They switched to Canna Terra Flora two weeks ago - is this a over feed or deficiency?
