Could be a bit of moisture build up and your lights just roasted that spot slightly. I wouldn't worry unless it starts to spread or you can see it from underneath. Happy Growing!

Reddening of leaves quite prevelent at top of plant. Think it might be a PK deficiency. Question being - is it too late to add a PK booster at this stage of flowering? [Or will I have to ride it out?] Thanks, Harry

Minor damage to a few leaves found today - what is it?
I am trying to determine the cause of damage to a few leaves that was observed this week. It may be two different problems. On a few leaves, I see brown spots which may have originally been white. On another 2 leaves, I see a burn hole through the leaves with brown edges.

Largest plant's bucket got empty on accident; Filled a 15gallon reservoir of full strength nutes and pumped the solution into the bucket as always. Next day my largest plant is dying and the other two are fine, looks like lockout. Flushed for a day and then added nutes, nothing..

Cal mag deficiency? White leaves
Does the whitish leaf in the last pic look like cal mag deficiency? I just started adding it along with tiger bloom. They don’t seem to have powder on them like mold, just seems like the leaf is going white from the inside

What are these spots?
What are these little spots? I only have them localized on this one leaf (and one plant out of three), and haven't seen anymore. I'm more curious than anything. Tips to fix? Don't worry?

Help!
The leaves are limp.. could anyone diagnose the problem of these plants? The leaves stand down, both when the pot is full of water and when it starts to dry. Could it be an excess of light or a lack of air? I had the inlet fans at idle!

Spots under lower leaves
Spotted some black & white spots on some of the lower leaves on wedding cake. Can't see any bug but to me they look like eggs. Any ideas (the spots appear on the lower leaves only, top leaves look ok)

What could this spot on the leaf be? It has been visible for the last couple of days and it's been growing WITH the leaf and not independently.
She has this one spot on the leaf. It is only on the upper side, meaning if i look underneath the leaf there is no such mark. I have no idea what it could be. If it indicates some sort of problem then I would like to get it under control before it propagates any further.

Spraying the leaves
While I was checking my plant I saw these “black stains” like the plant is “half-bitten/scorched”.Is it possible to burn my leaves and create this effect after spraying them with nutes. Blacks spots were created today after I sprayed them and there were drops on leaves for hours

Cal deficiency?
Is this a problem or nah? Brown spots on leaves, mostly on the one plant that is farthest behind on flowering. Thought it was calcium deficiency also contributing to slow flowering so I hit the plant with some nutrients a few days ago. Concern or just end of life stuff? Thanks!

There seems to be some paleness/yellowing on the upper growth. Upper leaf tips are slightly curling upwards and show some dark purple color. Last week runoff PPM was hovering around 1150-1250, so I'm dialing it down closer to 1000 ppm this week. Too much nutes or light intensity?
