Indoor Help first grow!?

[RakeOne]

The whole plant is looming yellowish, limey. I’m growing in coco mixed with perlite and cocloco. My ph has been between 5.8 and 6.0. I’m using General hydroponics nutes. All of them. Also using mammothP. My ppm was 380 on last feeding. Fed 1 gallon per plant. They are in 4 and 5 gallon buckets. They all drain really well. I did a flush about a week ago and my ppm coming out the bottom was 1600 ppm roughly with 5.8 ph. I flushed with Florakleen and RO water. Then last feeding was the 380 ppm. I am on day 39 from seeding popping.

It is really hard to tell in pictures under that type of light what is going on. It looks like a phosphorus deficiency. Coco loco is a wild card and no way to know what is still in there? We need more information and pictures under 5000k light if you can manage. 380 PPMs is too low. How do you monitor PH and what is it?
