I believe this is a phosphorus deficiency. Strawberry fields soil till soil nutes ran out. 5 gallon pots. i noticed 2 fungus gnats stuck to two colas so i fed twice every other day root cleaner. Cyco nutrients suggest 5.5-5.8 for soil. I changed it to 6.2 week 6. My other plants in week 3 are starting to show shades of purple. At night the temp goes down to 60-65 but no less than 60. ppms at first were 1200 per instructions but figuring it was cookies i dropped it to 1000. My gorilla glues and gelatos aren't turning purple but are fairly smaller after you guys help me with this i can show pics of those. No mites no pm. No overwatering. sometimes they wilt just a bit on the other day of feeding at night Before i feed But not full on wilt. Also the leaves at the bottom end up turning brown and dying at the very bottom of the plant under the net.
