I am experiencing a problem on both of my trays. Tray 1, I'm getting yellow leaves starting on the bottom and working its way up to the cola. The leaves at the very bottom have pretty much died. One node up, they are yellow and the ends are curling up. The next node up they are just yellow, some with green veins. The tops of the plant seem fine with just about 1/2 mm of yellow on the fan leaves end at the very top.
My other tray, tray 2....Some of the plants are very light green with the lower fans curling into themselves.
First thing I thought of was magnesium deficiency. I am using Canna Nutes (Vega for veg, flores for flower) and I read that they are magnesium deficient and you should add Epsom salts if you are going to use this brand of nutes.
Stats of my op.
1 1000 watt HPS, cooled (You can touch your hand to the tube, warm but no burn)
Canna Nutes running at 800 PPM. Tray 1 is at 3 weeks in flower (SOG), tray 2 is at 2.5 weeks. What else.....
PH has maintained everyday at 5.7-6.0, if it has hit 6, it gets knocked back down to 5.7. Temps have been at 77-83f the entire time.
Medium is 15% Rockwool Floc (Al B. Fuct style), 85% Perlite. They are being fed twice daily, once after lights have been on 1 hour, and the 2nd watering 2 hours before lights off.
