I have a serious problem with two of my girls and I can't figure out whats wrong. The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?

I think you have toxicity. Check the EC of runoff. I'm also not intimately familiar with your nutrients but make sure you're going low on the N. Otherwise check the pH of feed and runoff, if you're overfeeding, your runoff will probably be super acidic, causing uptake issues.

Man I always see this issue and everyone always says it's a feeding issue... It's not.. look up leaf septoria.. it's a fungus that's so common in nature I dare you to go outside and find a tree without it.... Do yourself a favor.. google it, you'll see it's your problem.... From there just remove the most affected leaves and keep everything clean for next time... It will only effect yield if you don't remove dying leaves because of the energy used trying to keep them alive... Other than that it's a leaf only issue

Fabric planters need more water to wet the entire root system. When they fill with roots they become very hard to get water/ nutes through the entire planter leaving dry spots in your root zone. Water comes out the sides before reaching the bottom. The dry areas in your root zone make the plant develop brown spots in your leaves, usually mid to near the top of the plant. More water, make sure all your roots are being fed. Easy on the nutes and you should recover. Cheers
