Hi all,
This is my first grow and I think I made a bad choice with soil.
The seedlings are 2 weeks old and one has little brown spots on the first blade leaves and the other has very strange dark first blade leaves.
The dark leaves I think may have been from the heat stress in first few days as it has been like that for a week. the other plants brown spots started yesterday and slowly getting worse.
I had a heat problem in its first few days (up to 95 degrees) but have stabilised it now. Grow tent sits around 76 degrees with about 40 RH. PH of soil is about 6.5 going from colour chart with soil test kit. I water with ph'd tap water left out for 24hrs to evaporate chlorine.
I think the bad choice I made was the soil. Its Scotts osmocote organics potting and planting mix. I mixed it with about 30% perlite and a little propagating sand. The soil has a slow release fertiliser which feeds for 6 mths which I now realise was a bad idea.
They are NL autoflower feminized from vision seeds. They are already in large pots from the start as per advise I have read on here. Is it worth getting a better soil and transplanting or do you think they will be ok? They seem to be growing at a decent rate after recovering from the heat stress in first few days. Just worried the brown spots are because of nute burn and will not be able to flush at all because of the slow release fertilizer in soil.
