Weird one

[IMO]

Apologies if this has been discussed before, I have had an issue a few times now always indoors never had the problem outdoors, where the plant seems to show a calcium deficiency I,e brown patches on leaves and yellowing, but the other plants do fine with same medium light etc, as I say never seen this on an outdoor plant it seems as if some plants metabolism seem to struggle under the intensity of the led light even though I’m probably running around half the wattage I should be for a 1.2x1.2, maybe it’s an auto issue
thoughts welcome and appreciated.

I ask as I had this a few times. It turned out to be heavy elements in the water clogging up in the upper layers. It displayed as cal or mag and would progress to what looked like both hunger and lock out. Had a few of us scratching our heads. I ended up using omina and yukka by raw to soften the shit in the water.
