Question about treating N deficiency, 2 weeks into veg

Hey all, I've got two plants that have been vegging for about 16 days and I've been noticing a little yellowing over the past few days on the lower leaves. After doing some research here it appears to be an N deficiency (yellowing lower leaves, stunted growth), which kind of makes sense because they didn't start getting nutes until yesterday when the problem became obvious.

Here are some pics in case I diagnosed the problem incorrectly.



Some people have recommended I do a foliar feed with some nutes that have a lot of N. I usually water with FF, but I have some MG organic that's pretty much all N (8-0-0). I've never done foliar feeding before, so I want to know three things:

1. Will this help fix the problem faster?
2. If so, how much fert should I add to my foliar mix and how frequently should I mist?
3. Have I diagnosed the problem correctly?

Thanks all!

yes they could def use some N,in the veg state u should be feeding them some once every 2 waterings or so. A foliar feed will help it recover faster, i use fish agra.. mix 1/100 nutes into low ppm water so 1 ml nutes into 100 ml water. Your plants should recover within a few days, i would spray 2 days in a row

1. Not significantly at that size. Larger plants with the same problem benefit more because it's alot more work for them to move nutrients from the roots to the extremities. Once properly fed at the correct soil pH, they'll be fine almost immediately. The single bladed leaves won't recover but it will grow well again. While foliar feeding probably won't make a noticeable difference once they've been fed normally, there's really no reason why not, if you want to try it.

2. Most foliar feeds are applied around 1/2 strength but the safe way to go with something you have no foliar info on is to start at 1/4 strength and work your way up.

3. You most likely did. Grats. You'll want to check the soil pH if you haven't yet to be sure that isn't the cause or making things worse.

Maxicrop is our favorite foliar feed. Always alternate foliar feedings with plain water sprays, without spraying them too often.

Thanks for the help, guys. The lower leaves are staying yellow, but growth seemed to kick back into gear almost immediately. I'm using distilled water and the soil ph is between 6 and 7 according to my test kit, so it could stand to drop a little more. The nutes I'm using for the foliar are about 1/4-1/2 strength the bottle recommends for foliar feeding.

+rep all around, thanks again!
