2 plants (Purple Kush Autos) planted at the same time - 21st March - (in peat pots which I’ll not use again) in a 60% peat compost. Both seeds from the same packet. Kept indoors (UK) as nights too cold but transitioning to greenhouse in about a weeks time (hopefully), were they shall remain although I intend to pot-up into 20 litre pots in maybe 3-4 weeks.
2 weeks ago I potted-up into 18cm pots, planting the plant and the peat pot into a substrate mix of 1 part soil/2 parts compost (60% peat)/1.5 parts perlite. One week ago I gave them their 1st feed (Dyna-Gro GROW at about 1/3 strength).
So both plants have had the same water (at pH of 6-6.5) feed, substrate, light & warmth yet one appears health and growing strongly (although it seems a little small for four and a bit weeks - but I put that down to a combination of insufficient light and the cold snap we recently had), while the other plant is hardly growing, has small leaves (which are yellowing a little) and just generally doesn’t look well.
I’m thrown as like I say both have been treated the same and have the same environment yet there seems a world of difference between their growth ands health and I’m kind of bugged. Would love to hear any thoughts? Thanks
