The large plant is Barneys Farm LSD and the small is a Siberian(Flowered straight from seed).
Ph is 6.3-6.5
soil, 3 gallon pot
Jacks blossom fertilizer as recommended for indoor plants.
Watering about half a gallon every three to four days, when the soil is completely dry at finger depth.
250 watt HPS, 12-14 inches away
Temp is ~81 (nothing I can do about that at the moment unfortunately)
Not sure if it makes a difference but I'm at 7500ft above sea level and have a RH that runs between 35-45.
Had a fungus gnat problem for a bit but got it under control with DE.
I'm having yellowing on the sugar leaves and fan leaves that seems to be starting at the tips and working it's way to the base. It's not isolated to top middle or bottom, pretty evenly spread. I thought it was a nitrogen deficiency but saw no improvement from adding any to waterings. Now I'm thinking over fertilization but wanted to make sure before I flushed. Any help is greatly appreciated.
