This will be my first -post about my first attempt at growing Cannabis indoors. I feel i may have put my plants under some undo stress in the beginning as i was all too excited to give them the light they require.
I started with Clones under a 300 Watt LED (KING LED Brand) 12 in from the top of my plants and in my small veg tent the temperatures soared to 89 degrees. I kept them under the LED for another two days while managing the temperatures with an exhaust fan.
I started seeing discoloration in some of the larger fan leaves and browning on some of the newer growth. I assumed lightburn and have since kept them under a 2ft 4 bulb T5 panel. I have been keeping them on an 18/6 cycle. However in the past two weeks i have only seen minor improvement with new growth and still my fan leaves are yellowing and browning. (See Pictures)
My questions are thus:
For the 5 Plants i have now, is the lighting i am providing adequate? ( I was thinking about getting another 2 ft 4 bulb panel) Should I maybe go with CFL or HID MH?
Could this issue be a lack of nutrients?
My Humidity is hard to maintain and is consistently in the low 30's, i mist 3 times daily! Any easy recommendations before i go out and buy a humidifier?
Any thoughts or opinions would be greatly appreciated.
