The light markings between leaves is magnesium and spots are calcium sign. Also showing potassium deficiency. So I am perry sure your ph had drifted upwards too high in that one.

Cal mag. Your ph is likely too high in this one due to coco amount used in substrate. So your experiencing a lock out.

Bottom leaf turned yellow with brown on edge
Hello this is my first grow and had noticed a leaf turned yellow with brown spot on the edge. This is a northern light auto just kicking off with her flowering. I use advanced nutrients 3 in 1 micro grow and bloom and that's all I've ever used. I suspect a nitrogen deficiency...?

Some advice for the newbie please! Yellow spots on the leaves.
Crushed Seashells in with the medium for calcium.Been spraying insecticide the last week. The last 24hrs I have cleared some bushes around her, could an extra 3hrs direct light cause this? I am watering 2ltrs of water every 3 days.

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
