I threw some of my composted soil (not sure exactly what was in there but mainly fruits, vegetables, egg shells and bread) into my pots for this grow just to see how it would go. Now I’m starting to see some twisting leaves and browning/drying. Not sure what nutrient is causing this and how to...

One row of my lilac diesels are affected only. This was after a bad storm. Is this wind burn, nut burn, pests? Help! Suddenly leaves turning purple/brown and entire plants dying literally overnight. No evidence of root damage by tunneling pests or verticillium/fusserium. Pics attached.

Hi guys, Over the past few days I have been noticing these spots and discolouration of the leaves. I have moved them into my main room and turned the LEDs up to about 50% (4x 600w LEDs). They aren't too close but the plants got too big for my liking as I wasn't able to transfer them earlier I...
