Looks like the gash of a finger nail or some other hard thing that slid against it. Especially if you're not seeing more anywhere else. 👍

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…Leaves. Color - Yellow

Brown spots, PH in run-off is in the high end (6.5~)I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?3y ago

Fellow growers, after a few weeks of beautifull growth, I now start to get yellowing leaves which dry up and starve. I am. I am doubting between a lack of nutrification or over nutrification. I suspect the latter (biocanna nutrients and soil). Any ideas? Thanks!!Week 6

Spots on leavesI'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue.
Still look like PH fluctuation?6y ago
