Curious...what specific comments are you calling "stupid comments"?

Again...filling out the troubleshooting form is the best way to a definative diagnosis. Or, you can keep offering these little tiny bits of info, till they're ready for harvest. :thumbsup:

Growing in the desert I know exactly what heat stress looks like, and that's not it. With heat stress, the leaves thicken and raise to the light.

Old leaves are old news. Your ph is way too low for a peat-based grow, and the affected leaves will not recover their vigor or shape. Correct your ph, and new growth should be fine. only other thing I can think of is to lower the lights if possible. 2 feet from a 400w is pushing the outer edges of it's effective range.
Rusty Trichome Reviewed by Rusty Trichome on . WTF is this all about? Is it a mistake or a mystery These are 2 diff plants, 2 picts each. They are from the same Blueberry Tundra seeds i accidentally breaded (Blueberry Kush/Matanuska Tundra). As you can see they are mad and making a fist. No purpling of stems so i don't think it's a K problem but i may be wrong. Could this be a bad water issue or something more specific. These are the ones that had the 5.8pH that I flushed 4 days ago. I gave them a shot of floraNova yesterday. My MT has been on the same routine since i set them to flower. Rating: 5
