Rust looking spots
STAYINGONMYMAINCBATORUNTWO
started grow question 6y ago
Anyone know what this is? It’s only on 4 of the bottom leaves of my purple lemonade! I plan to give them cal/mag on their next feed to be safe but knowledge is power?! And I would like to know for certain!

What is the PH of your substrate? Looks like needs some calmag to me, however could be other things depending on the PH.

What’s wrong!
Any ideas what’s wrong with this plant? None of my other orange sherbets look like this & they are all in the same environment & getting the same nutrients?

Brown spots developing on leaves.
Started noticing little brown spots on the leaves of my plant today, I’ve read anything from calcium deficiency to water droplets causing burns. Any input greatly appreciated.

Any reason to be worried? I have 7 plants going, 5 on the same feed. Only 2 plants are doing this but they are on different feeds. One has been mostly water and the other has been on the same feed as the rest but they are all fine.

Dying leaves?? - Brown spots lower leaves
The cotyledon leaves are dying on one of my plants, but these brown spots have spread across lower leaves that were damaged by the shell. Is this natural or is it a problem I’m unaware of? Not over-watering and pH is fine. Brown spots have appeared on tips of next leaves up now!

First grow with autos, are these growing too slowly after a week?
It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

What are these leaves saying?
What do you think these symptoms are saying? PH was low for a couple feedings before this photo (4.9-5.4), could that explain this? The coco doesn’t stay too moist so I don’t think it’s overwatering. Could it be underwatering? I do have roots trying to get out the drain hole now
