Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated

What's causing my brown crispy leaves!?Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Leaves curl on upper new growth and mid but not lower.I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

browning leaves Anybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?

development problems I'm having problems with the plant. The lower leaves are drying out and spots are appearing. The upper leaves are curling and twisting, and there's an unhealthy color. pH is 6.5, PPM was 600 but I lowered it to 420 yesterday. Suspecting either a nutrient overdose or a pH issue. Check out the photos from the second week (day 10).
