You didn't get any input in three days. Maybe its because you skipped some important questions from the form?

What is the light schedule?
How much per watering?
What are ingoing outgoing pH (runoff)?
Additives how much?
Do you foliar feed?
Were they from seeds or clones?
These are from the form but don't limit yourself with them. Add as much useful information as possible. About your soils nutrient level for example. Did you repot or were they in those big pots from the beginning? etc...

Hopefully you can get some answers after all.

All I can tell is, you have blood meal there, adding more nitrogen looks like not a good move and you should definitely think there may be a pH issue. Pots are big, think more about over watering. 3 days may not enough for them to dry completely when there are tiny plants in them.
