Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?5y ago

Dinafem cbdAny suggestions? This is my first time doing a dinafem cdb strain and it's just not looking right. PH is good and not overfeeding. For some reason it's just not looking right. Never ran into this issue before any ideas? Or is this just a common look for a cbd strain?Leaves. Other

Leaf/folliage Misting/SprayingHi! General question about leaf misting. I'm starting to do it before lights out but can it be done under lights too? I know from limited gardening experience that it can be detrimental to leaves but is the same true for our girls when under LEDs? I'm using a Mars Hydro TS1000.Week 2
