This is what i mean, looks like nutes when it seems to be more overwatering. Of course it looks nute deficient, so would any plant if its roots were overwatered and constantly wet. Those crispy brown bottom leaves aint nitrogen deficiency it overwatering, well in my opinion. You cant feed nutes till the overwatering is solved, heal the roots then feed, should only have to let the soil dry good once or twice. Leaves should be standing up straight not drooping like that, 6 weeks veg is long time for a smallish plant like that but hey it dont look too bad really. They certainly are in decent sized pots.
Goodluck
