Yellow spots on the leafs
m0useanswered grow question 7 months ago
I do not see any N tox going on. The leaves can point down for multiple reasons. Wth N tox it is accompanied by Dark glossy and brittle leaves. I do not see any of that with this plant.
Check out the leaf symptom chart. This is one of the better ones.

Yellow of the tips can be caused by issues withe roots and also by light or even potassium.
BioBuzz recommends to not go below a PH of 6.2 with its products. So I would check that part first. Then work your way though the leaf charts.
You can check your lights recommended dim and hang heights from the manufacture.
FYI, this is the feeding chat for your product line.

Calmg is on it, might want to include it. as the leaves are showing it a bit.
Good Luck!

You could be lacking a little magnesium or your rootzone might be too acidic for the available magnesium to uptake. Test your runoff pH to see if your rootzone is out of range(5.5-6.5 coco, 6.0-7.0 soil).

Although getting nutrient water on your leaves during the daytime hours can burn them, that is not what I see here.
I’m seeing two things. First it looks like your leaf tips are “clawing” down. This would indicate too much nitrogen.
Second I’m seeing more yellowing happen in the leaves mid sections that is kind of strip looking at each notch which would indicate possible magnesium issues.
I hope this helps.

Is this light burn?Is this light burn? If not what is it?
It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb.
I plan to add more but don't want the issue to accelerate.
Thanks in advance!
