Nitrogen deficiency!!!!

So i have some questions real fast guys hope you can help me out. So like 4 days ago i had a nitrogen deficiency and fix this problem i took my bcuzz A 3-0-3 and kicked it up 25%. I was at 900ppm and i kicked it up to 1000ppm. I have 9 plants all together. Most of them are fine now. But there are still 4 of them that are showing a couple of leaves here and there that are still nitrogen deficiency. So my questions is should i kick it up another 100ppm. On the plants that are still showing it.Are just keep it at 1000ppm. Oh and iam growing in soil 50% sunshine 25% ocean forest 25% light warrior with 2tsp of lime per gallon of soil. Another question is for my watering i do nutrient,nutrient,water. And my next watering would be water. If i did that would that make the nitrogen deficiency in the plants not showing it any more come back? And the ones showing it would that make it worse. Any help would be great.

3-0-3? thats an odd mix.

get some other nutes. get one thats heavy in N like 9-2-3 (what i use),then another thats heavy in PK, like 1-6-6.

that way you can dial in the nutes to exactly what they are in. 3-0-3 has 0 P as well, thats not good, the plant uses a LOT of it throughout its life and over-feeding P is rare

I mean thanks for the advice. But that dose not really help me out right now. Buying new nutrients i can do that my next grow.I mite do that.Because i know its not high at all. But what can i do for now.Is what i want to know. Since my nutrient A is so low dose that mean i can i should just add more. My B i use is 0-2-4. Oh my plants are in veg.I dont think i said that.

100 ppm up or down doesn't do much. you can easily raise 100ppm per watering until the deficiency stops. However, check your pH to see that the N is actually getting to the plant and not just creating salt buildups.
