Round and brown duts on the leaves

Rob691started grow question 3y ago

I have 7 plants in the room, and one has those small round and brown duts on the leaves. Ph is under control and I feed them with 1L with nutrients every 2 days following Biobizz's nutrient skudull. The others looks quiet balanced.

What diary/grow are you asking about here... I would need to see what you've been doing/feeding and various other pieces of information... it's definitely a calcium deficiency but if I knew the diary, I could tell you why you've got it and what to do about it (and it doesn't matter that the other plants don't show the same signs - each plant is an individual and will react in their own way). I'll try to check back here to see if you've put in a link... thanks...

I'm not sure, I've been looking at it for a while.. try giving it some, it should stop developing these spots in a day or two, but if after a couple of waterings with the correction it keeps spreading, it could be something else..

Well.... after investigations it is probably the beginning of a calcium deficiency. I'lll correct from 0.5ml/l to 0.8ml/l in the next feed.

Calcium deficiency?I recently bought Calimagic for my calcium fix. Prior to this week I have been using tap water for calcium. Is 2mL/gallon of calimagic too little? Noticed some leaf damage I believe to be calcium deficiency. Does she need more calmag? Thanks for your help all!

Lemon Ice 2.0 - Browning leaves Weird Growth Anyone got an idea what may have caused the weird looking lemon ice to grow like that?

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?
