I am growing jock horror under 250 HPS + 4 26 watt 6500k CFL. I am 2 weeks from sprout the cotyledons have started to yellow is this normal? im using a waterfarm with hydrotron and GH flora series nutes 1/2 Recirculation schedule. I dont have a EC PPM meter. Yes I should invest but its tough living in these times.
