I am using the HLG 600Rspec using about 400ppfd if my meter is calculated right in a 4 by 5ft room with 4in.ventilation. it’s hot n muggy here so I do have the AC duct open alittle keeping it toward the ballast so humidity is fairly low it is a 100per cent afghan strain I purchased from here and am using fox farms happy frog soil in 5 gal. buckets. I have been using mostly earthworm tea and alaska fish 5/1/1 but have thrown some cal/mag to um recently thinking maybe my light was to intense I have used distilled water since day one and my ph has been between 5.5 and 6 my N always seems to show very low my P a little low but my K very high from first sprout they are just under 6 weeks old any information here will be greatly appreciated I have grown outside for year’s up north but this indoor thing is all new to me…thanks bunches😁

I don’t see any issues. Looks like she could use a TINY bit more N but don’t overdo it.

A drink of epsom salt should green them up. The light you’re using can make the plant require more magnesium. 1/2 tsp of epsom per gallon should do her well.

Nice set up. You might upgrade ventilation to at least 6" to 8" exhaust. Other than that you’re set nice.

In soil, and since I too use Happy can offer a suggestion, your pH should be between 5.8-6.8 with 6.5 being your sweet spot.

I thank you I’m just letting everything soak in to my brain for round 2…hope I have enough room up there 
I was just looking at um wondering when I should flip um,I guess only time will tell,but by my 2nd crop I will be more knowledgeable.its a little addicting but is what I missed most after leaving up north,up north I could just throw some clones in some donkey shit and know they were happy

I don’t see any signs of calcium issues. You have a pretty wicked light so it is going to cause the plant to use up more magnesium. Just a little magnesium boost with epsom salt, here and there, will take care of that.
