Hey there
My first seedlings is starting to develop strange discolorations on the leaves and I cant make out what's the problem. They have been growing very slowly and I suspect its the cold temperature (15 degrees Celsius average) but as a newbie i cant be very sure. Here's some info:
-Small grow box (0.175 cubic meters)
-4 CFL's 2500K, about 600 lumens each
-Self-mixed soil (potting soil, palm peat, pearlite) decent drainage
-Flushed the soil before transplanting, but didn't check PH...
-Using RO-water (PH corrected)
-Humidity range of 50% - 60%
-Have been feeding nutrients, but VERY little...Like every 5th time I water
-Watering when soil surface is crusty (every 3 to 4 days).
Except for slow growth, all went well until recently when the discoloration began and I would appreciate any advice or tips. My grow box is still a work in progress, I need to add vent fans to draw in fresh air because at this stage I'm opening the box during daytime to allow for fresh air to circulate.
