Hi,
2 out of 4 plants have recently had a few top fan leaves turn purple in places, this only happens on upper leaves and the purple starts at the tip end and works inward. Grown this plant before and didn't have this.
-Can't remember name of the strain, but it's sativa I believe
-In week 4 flower, this started 2 weeks ago
-20l fabric pots
-Hand feeding from top with a little run off each day
-Coco/pebble mix (60/40)
-300w led lights currently at 100%, 15" from canopy
-Feeding shogun nutrients, using tap water with a little calmag added
-Using co2, was at 1100ppm in week 2, 1200 week 3 and 1300 now in week 4
-Temps around 28-30⁰c, 82-86⁰f, day and around 18-20⁰c, 64-68⁰f night
-Humidity trying to keep around 55-60 day and a little less at night
-Diffuseair fans mixing air plus a few floor fans blowing just below canopy
Think i was a bit too hasty with light strength and heat after turning on the co2, caused a bit of light and heat stress in late veg, early flower, but I don't think that's related to purple leaves?
Thanks!
