Nitrogen deficiency? Fertilizer?

I’m growing my plants outside in soil. Have been looking pretty good though recently I’m getting a lot of yellowing leaves. Reading on the internet, I’m thinking there may be a nitrogen deficiency…. Wondering about fertilizers. Which fertilizer do you recommend? Solid vs liquid?

Any tips are much appreciated!!

BTW- the clones I posted about before are doing amazing! Thanks!!

I am leaning more toward just generally hungry.
What kind of feeding have you been doing?

I think @Spiney_norman is right…they’re starving. I’m different than most of us using Jacks dry fertilizer. I have well water and I use Jr. Peters (Jacks) pure lx 17-4-17 for all of veg starting at 14 days. Most here use Jacks 321 formula which is great too. Dry fert. lasts a very long time. I have a couple of years left to grow of both veg and bloom formulas that I bought 30lb bags of in 2020 and it grows weed really well. I used to use the GH flora line of nutrients which grew stuff real well but I bought a whole bunch to grow with and it ain’t cheap.

Oh no! Didn’t know I was starving my ladies…. New grower here. I haven’t been ‘feeding’. Just watering.

What/how do I feed them? How often? Is feeding different than fertilizing? (sounds like it) How do I get them healthy again?

Thanks for the help!

You basically mix fertilizer with water unless you’re top dressing. You need a PPM meter to see how often. Feeding is basically fertilizing. To get hem healthy, prob just feed em

I use Jacks 3-2-1 as most do here for it’s price and ease of use.

Important not to panic. They will be fine for long enough to get some cannabis friendly plant food and get started feeding.
I also use Jacks 321. There are ebay sellers with small sized kits.
There are many other fine lines.
Fox Farms Trio is popular.
If you have a generic tomato food just give them a light feeding until you find something made for cannabis.
Dont use any type of time release food.

A Light Foliar at 25% strength will help to make up the lag for the soil drench to get picked up. But be sure whatever nutes you decide on for a foliar hit are mostly Mobile/semimobile nutes N P K MG S etc
