Ok, I have looked through countless posts looking for pictures showing the same thing I have, but couldn't find anything substancial. First off a little about my plants. They have been in the garden for about a month and haven't really grown all that much. I amended my soil with maybe 20% peat and 20% perlite and a handful of prilled dolomite lime. I have been using foxfarms and a combination of compost tea and light watering in between. I water about every 4 days. I grew 8 footers last year in Raised beds. This year I went with smart pots and I seem to have stunted my plants. I am sure that I have been using a pretty high nitrogen mix in both my tea (fish emulsion, both foliar and drench) and my regular fox farms nuts (grow). Everything I see tells me Nitrogen deficiency, but I'm not sure and don't want to burn my plants by poking holes in the soil to pour fert directly onto the roots. Can someone please tell me what you think regarding the pics. Thanks in advance

Id try some plain water with just cal-mag or epsom salts. Then a nice high nitrogen foliar feed. Some epsom in the foliar spray wouldn't hurt either (1/2 TBSP per gallon). Then start feeding them with 1/4 strength nutes every time you water. If the leaves get super green or claw up, give them plain water once or twice. If there's not enough cal-mag in your source water you'll have to supplement everytime.
My plants did the same thing. Now that I feed 1/4 strength and 5ml per gallon of Cal-Mag everytime. I have zero issues with my plants.

Mix in vegetative ferts high in N to your solution, tea or whatever (don't pour directly on soil)...if you are on FF it would be Grow Big.
Looks like N def. Overall appearance is light green, lower leaves yellowing and falling off, ect. I don't think it's any biggie yet, but you want to get it corrected and growth should normalize.
If you do a folliar of Cal -Mag (wouldn't hurt), dilute it pretty good or you'll get spots on your leaves where there was too much and burned them.

Yea, I figured it couldn't hurt to try after reading Stomata's post. I'll use a strong foliar feeding with a touch of cal mag tonight. Hopefully that fixes the problem. I'm curious though, why not drench the soil? Just in case the nitrogen problem is from over fert?
You said (don't pour directly onto soil), that's what I was meaning by "DRENCH". Just wondering why you said not to feed through the soil, but instead to just foliar feed. Not a big deal. I'll do a foliar feed with some good high nitrogen ferts and some cal-mag here in a couple days.

That could be anything but my guess is the dirt

The dirt? You mean the same dirt that I grew 8 footers in last year?
Ok, so there might be something to this "bad dirt" thing. In the past I have always mixed in steer manure into my dirt and built raised beds with that dirt. This year I changed to smart pots and amended the dirt with peat and perlite. I thought that the peat was adding high nitrogen content to my soil, but I may have been mistaken. I know that it takes a long time for my soil to dry out and it almost feels compact. I have been adding compost tea, but it doesn't seem to be helping much. The plants are finally starting to grow and darken up, but I'm having to add a lot of high nitrogen fetilizer. There are a million soil recipes but I want to utilize my existing soil so maybe someone can suggest a recipe that uses your existing soil as a base then peat or compost or potting soil additives to amend that soil. I wanted to mix a couple bags of black gold potting soil into each 30 gallon (or 40, can't remember what I bought) pot, but I have 15 pots. That's a very spendy item. That's why I went with the cheap peat moss and perlite mix. Guess I should have done more research.
Sooooo, what I need is soild recipes.

I added lime to the mix thank god, but you may be right. Overwatering may be the culprit, that reason is that the soil not draining correctly.

she looks happy, just a little hungry. i just corrected this on my plants too
Fuckin'-A Hank, that's s killer link. As I look through that shit, I think I have a Potassium deficiency. Probably due to poor shitty assed soil. Fuck, what do I do now? I guess all I can do is keep pooring the compost teas to the soil and hope that it starts breaking it down so I can squeak out a little bigger yeild. Thanks again for the link and that Leaf Defic. Chart. I saved to my hard drive.
Yea, I dumped a pretty strong mix with some cal mag and fed on the soil. They really really liked that. They're already starting to darken up. Now I just need to let them dry out and do a foliar feed. It keeps frickin' raining here so the plants aren't getting completely dry. Think I'll brew another batch of compost tea for the foliar feed and just add some nitrogen and cal mag to it.

Ive been hearing good things about cal-mag i think i need to get on the bandwagon. heres a pic of my plant that was having some N def.Yup, that's about what many of mine looked like. I just fucked up by not adding any nutrients to my soil mix. Going to mix half garden dirt with half Sunshine mix #4 next year. Should help out. Shouldn't have tried to skimp on the soil amendments.
