:smoking:It's a busy time of year mate, expect delays.....
Symptoms are lack in part of food in general, BB Light is very low in this.... you need to feed mildly while the roots reach the main soil, which you say is areal-deal TLO?
T and RH% at extremes are a problem for seedlings,... low RH%, high T can cause distortions of leaves, magnified by lack of food....
At this stage clover is something of a competitor for foods I imagine,... I don't so this cover crop thing, isn't that supposed to get started later after the plant has set some deeper roots?
Seedlings want consistent even moisture, which can be a pain I know at this stage,.. using the mister is good to spot water when the rest of the soil is still OK,... Lower light intensity too,...
pH is out of range, organic or not,... low to mid 6's is where you want both in-pot and water/feeds solution pH to be.... you can use citric acid as a mild pH down. Organics are less prone to go off pH, and perfectly functioning TLO may be "fully self adjusting", as long as the water isn't very hard which over time may drive it up from mineral inputs (CaCO3) .... regardless, look into getting a soil pH probe, like the Accurate 8 or a more $ Blue Labs unit.... Never be complacent about pH!
