Is there any 2 part nutrient with absolutely no nitrogen. I'm growing using hydroponics. Right now I'm using the lucas formula
2 part nutrient question

No, what would be the point? Do you have another Nitrogen containing fertilizer you plan on using along with another 2-part?

It just seems that I could cut nitrogen out during flower....I am using the lucas formula and even at 600 ppm Im still getting nitrogen toxicity going on

No, it's still an essential, you can never cut out an essential element. Lucas is pretty low in N, actually lower than ideal but it works.. What's the runoff ec?

My leaves are shiny, dark green and curled
2 different strains. You can see the really bad ones in the back curled, that strain is dogwalker. This shit happens everytime with different strains as well. I've tried 1/2 strength (around 500 ppm) and still get nitrogen toxicity. I dont get it.

I'm using gh with ro...I start out 1/2 strength for 2 weeks in the flowering stage and then go to full strength for the rest of the time. Ppm is at around 900...this happens all the time and I dont know what to do. My buds are really small also I'm almost at 6 weeks and they aren't as big as I would like. I think the temperature has something to do with that...it got down to mid 50s a couple times.
I'm using the ebb n flow method with no medium...any advice?

Hm. 3 part?
Try Lucas formula. 8ml micro 16ml bloom per gallon. (With ro a dash of calimagic upto 1ml per gal) No grow. Your ec will be around 1.6-1.8. Small plants like that don't require so much feed. I'd prob be bumping that down to like 1.2
Cold temps will def slow down growth and also in cold temps uptake of certain nutes is compromised. Takes in less p-k and more n.

That's exactly what I'm using is the micro and bloom and I added a little bit of liquid kool bloom on week 4. Even when I feed 4ml and 8ml I still get signs of too much nitrogen...I dont know if this matters but I only veg from clone for 2 to 3 weeks when I see roots and then flip them to flower

Ya I'd put my money on overfeeding small plants and cold temps hindering nutrient uptake.

So do you think I should try 2ml and 4ml...i guess its worth a shot...that's like 400 ppm though...maybe I should try that and then bump it up according?

The goal is to REDUCE nitrogen in flower, not go 100% without it. Everyone else pretty much cleared that up though.

Hm. I'm not quite sure what you should do my friend. If it were me I'd try running 1.0-1.2 ec for a bit. And get those temps up. Just mix normal then dilute it with ro to the desired ec range. It's not gona fix itself overnight. If it's built up in there it'll take a while to work its way out.
What lights you running?

GH trio is a great example. . ..sure you're not using the Gro in late flower, but you're still using the Micro with the Bloom, which the Micro actually has a higher N value anyway. ..

I'm using 300 watt cob led lights....one set for each table. You thinking maybe I should just give them plain water at this point.

Very true. With Lucas formula though it's pretty much like using gh maxibloom.

I don't want to give you the wrong info. Looking at the plants in the pics I don't see a huge problem that you should flush. Plus flushing is more for mediums... Not the plant itself per say. you said week 5? I mean it's not terrible... you have time to go. Remember in cold temps your flower time is gona be alot longer than in warmer climate.

Out of curiosity what do your roots look like
