Bottom leaves yellowing and droopy

My plants are 4 weeks into vegging and the bottom leaves have started to discolor and become droopy while the top ones are just fine(except maybe they feel a little rough on touching). I was thinking it could be a N deficiency but they're on a Grow-Micro-Bloom diet from AN. Also, only the bigger ones seem to be affected by this, the smaller plants seem to be just fine although i treat all my bitches the same way. Is it possible I'm not feeding them enough? This is my first grow and I'd appreciate any help

Nitrogen def sounds like it, single out one plant n feed more. If she bounces back you know what to do. Plants use a shit ton of nitrogen during veg.

Thank you. I was also thinking it could be under-watering. Right now they're in 2,5 gallon pots(i'll transplant them next week), are about 9,5 inches tall, the light is supplied by a 600w MH lamp and i water them only once a week whith the nutes. Could that be the problem?

How big are your pots? How big are your plants? They could be rootbound and wanting more room. That would lead to a variety of symptoms that appear to be a deficiency. If you are using Advanced Nutrients you most likely DO NOT have a deficiency. If your symptoms are on older groth it is from something less recent. If it moves into newer growth you have a deficiency. Now is the time for you to learn about mobile and imobile nutrients if you are not familiar.

The symptoms started 3 days ago on the leaves that are on the branches that appeared after i fimmed them. I was considering the pot size as the cause so i am transplanting them in 5 gallon pots as soon as i get the money to buy more soil (3-4 day at the most)
