I first noticed that the plants started to have VERY slow growth and were turning light yellow starting at the bottom with the tips of the leaves dying and they are droopy with no change after watering, then a couple of weeks later some of the plants started to develop small brown spots on the leaves.
Using a drip irragation setup, water 4 times a day for five minutes. I place cloans in 1" rockwool cubes then when there rooted I place them in 4" net pots with hydroton. The plants are in the veg stage have been in the room for 6 weeks and there around 6" to 10" tall. I keep the PH at 5.5 to 6.0 I have the PPM at 600 I check this using a Hanna electronic meter, since I've been having problems I have recalibrated it many times. I change the water in the reservior every 3 weeks using RO filtered water keep it at 70 degrees. Using Technaflora B.C. hydroponic nutrients I mix in the B.C. boost first using a 2 to 1 ratio use Advanced nutrients PH adjusters. running 1 1000w HID about 2 feet from the plant tops at 18on 6 off, day temp 75 night 65, have lots of fresh air flow. Have inspected for bugs and found none. I am thinking possiable Nitrogen deficiency based on other posts but not sure.
