Filling out the troubleshooting for would be best, but looks like a ph issue. Suggested range for peat-based potting mixes is between 6.3 and 6.8 ph.

What feeding schedule are you using? Do you stick to it?
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
