Is this a deficiency?

I’m feeding 550ppm of advanced nuts micro grow bloom. In 4” rockwool cubes. This is week 4 of veg and everything was going great until now. Temps are 73 and 60 percent humidity.

Why are you feeding bloom nutes to vegging plants?

I am just feeding them a very small amount of the bloom nutes. Mostly the micro. Could that be the reason for this?

Some people give seedlings bloom nutes, could be why. I have even seen certain companies that recommend to use their bloom nutes at a lower strength during this stage of development.

OP, is this week 4 of VEG, or are the plants 4 weeks old?

Thanks for the input, I looked AN bloom up and it's a 3 part nute, I've never used it but I use GH3 part so I considered that the first question to start with, as it's possible something might be off balance ?

Week 4 from transplant

If you're using equal amounts of each bottle (as the AN schedule calls for?), that's an NPK ratio 1.33-1-2.67. That K sounds high to me. I would do 1.33-1-2. (But, other schedules like GH Flora 3-part hit x-x-3 like that. It must not be a problem.).

Maybe it's something about the soil? Have you used this 3-bottle product before?

My impression has always been that this is AN's version of GH 3-part. And, if you're in soil (not soilless), I think using a hydro nutrient in soil invites problems. (Not that it can't be done. Just that you're bypassing the soil, missing an opportunity to feed the microbes with nutrient sources hydro growers wouldn't put in their reservoirs.).
