The grow was started in a cold attic in December and started well, germinated in root riot cubes and all 4 showed in 3 days. Potted into Clover MP with a 1/3rd perlite with added Mycorrmax. I had slight problems on day 5 after feeding 0.5ml/L Bio silicon on day 4, coupled with a drop in root temps.
By day 7 I was seeing slightly yellowed tips and a few rusty spots.
