Sorry dinafem but I'm betting on roots not getting oxygen.You mentioned hydroponics but since roots have not reached the edges of the pot yet and they are still in that turf media,you've clearly been overwatering.FloraGro and Micro at those rates will surely make healthier leaves and faster growth but problem is,you are overwatering too often for that seedling and it can't get enough O2 to its roots.that's why leaves looking very pale and new growth to be droopy.just give it some waterless time,let the soil dry out,this can take 3-5 days.dont water for 3-5 days problem will go away.giving bloom fertilizers in veg won't cause any problem,plant just wont use them,you'll be wasting the bottle that's all.
