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

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Deficiencies? Brown spots, yellowing and purple stems What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.
