indoor or outdoor indoor
soil, soilless, coco hydroponic Soil
specific medium Sphagnum/compost
Soil type/brand Premier sphagnum/local compost
Anything you have added to the soil Worm Castings, Perlite
Soil or slab runoff pH 7.55!
Water source Bottled
Source water pH 7.73
Age of plant 4.5 months including 1 mo reveg
Type of fertilizer Metanaturals 3-3-3, Superthrive
Rate of application 1 tsp/gallon H2O; 1/8 tsp/gallon Superthrive; given two or three times a week
Lighting source and distance from plant First used 6500K CFLS for ca. 3 weeks; 400W CMH now, initially 6-7 inches above plants for 4 days; later 18" above, last two days
Air temperature First 4 days of CMH = 73-83.5 F; last 2 days 66 - 75 F
Air % Relative humidity 23 - 28%
Lighting schedule 18 on, 6 off
Type of ventilation your room has Stanley blower air colled hood exhaust, 6 inch duct booster fan for active intake installed 2 days ago
Additional information:
Just noticed the problem about 3 days ago.
Strains are Nirvana Pure Power Plant and Critically Smashed. They were started late and grown outside, so the soil also was outside. Have already had a round with spider mites that I knocked down with neem oil.
Grow room is a DR80 tent (2.75'x2.75'x5.25') set in a closet; barely fits inside. Passive airflow wasn't cutting it (temps above 80 F) so I added the duct booster fan two days ago, temps run about 2 degrees F above ambient now. I can't raise humidity at all even though I put a room humidifier in the tent. Probably too much air flow.
I just ran the runoff pH tonight - I thought it was much lower, so maybe that's my anser, and I need to flush these girls really good with pH adjusted water. (?) Thanks for any comments or suggestions.
