yellow spots, just 1 more week ..

So I have one more week before the garden is done and I can get my broccoli in and I'll be darned if I'm going to lose these guys now. They are beginning to get yellow spots on some of the leaves. I think from what I could find it means they have a nitrogen deficiency and they need to be fertilized - does this sound right?

Also how do you know how much fertilizer to feed them? I've given some of them a little bit of fertilizer one time and by little I mean little.. like maybe 1 tbsp of the ferilizer/water mix (diluted slightly more than advised on the fertilizer instructions). Maybe that wasn't enough since even the ones that got the one fertilizer are showing the spots? I know you have to make sure they are well watered before the fertilizer so the roots don't burn. Just need to get them to hang on one more week and they'll be happy in the garden.

I'd try fertilizing half of them, see what that does. I always just go ahead and soak the roots with my diluted fertilizer mix; my understanding is, as long as you have the right ratio of water to fertilizer, the amount of fertilizer+water that you add doesn't matter. For example, I fertilize with fish emulsion. I measure the tablespoon or whatever of emulsion in the gallon jug of water, mix, and then I pour it in a seedling flat and bottom water as I normally would. Once the cups are good and heavy/full of water, I take them out. I usually rotate several flats of seedlings through that one batch of fertilizer+water until it's all been soaked up (in the course of a couple of hours, I don't let it sit around or anything, stinky!!). Hope that helps, someone else chime in if I'm incorrect in my thinking.

Sleepy is right on the money.

I use 1/4 of what is stated (on the fert. conatiner) what I first start fertilizing. so if they say one tbsp per gallon I would use 1/4 once a week. I do not pre-water and then add fert. It is one process once a week and if they need water between that, I use plain water. I also use a 1/8 mix all of they time (everytime I water) with great results. The fert. is already in my watering lines in the greenhouse so it is easier to remember weak everytime than once a week stronger.

Most of my seedlings are mature now so they get full strength once a week
