Hi all
I have some girls ( I hope they are girls) about 1month old, and theyr'e only 15 cm high. The grow medium is 70% Coco coir, 20% perlite and 10% worm castings.
Air flow in the room is good, 400W MH. Temp is constant between 23 and 26 C. Humidity sits at 30-35, and I can't get it higher, not even with a jug of water inside, setting the extractor on a timer etc. All has failed. Any suggestions?
Also, the plants are droopy and pale green, they are fed enough N, as well as micro elements. I have done experiments, watering, overwatering and letting soil dry. They still seem to droop and not pick up green colour. Could the medium draining fast have anything to do with it?
Please assist guys, I have been trying growing for some time now, and just can't seem to get the start right.
Cheers
