Fabric planters that arent having enough water put through can cause these problems. Water starts to channel through like a river leaving areas of your roots without any water at all. Water to runoff always and let sit in it runoff water until it wicks some water back into it. Also check that waters ph and ec levels and keep them in check. Cheers

Soft hanging yellow leaves, some with brown spots in the middle. Deficiency, Nutrient Burn or what could cause this ?Hey guys, I got a problem with two of my 4 plants. They started to develop yellow droopy and soft leaves that start to fall off on their own.
I’m not sure if it’s a nutrient deficiency or blockout from ph or something else.
I watered them only with water ph 6.5.

Lower leafs getting yellow tips and spotsI just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake.
They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.
