Does anyone have any idea what's ailing my Tomato seedlings?
Their growth is quite stunted - they're approx 6" and the underside of the leaves is tinged purple (it's not a mould though). The top of the leaves looks blotchy too but not with purple, it's like a yellowy browny spotty.
I don't think it's a Phosphorus deficiency - there's plenty of BF&B in the pots and the greenhouse doesn't get cold enough to create cold soil which would prevent the plants being able to take up the Phosphorus. Unless leaving the greenhouse open at night would make it too cold for them?
Could it be ventilation? The greenhouse has a door left open and 2 windows but the windows and door are all on the same end so the other end of the greenhouse can get a tad warm.
I'm really stumped and totally cheesed off, I never had any problem like this last year.
