These plants are 29 days from seed today. They sprouted in red solo cups, under CFLs. They are now in 3 gallon smart pots under a 600W metal halide. The soil has been Fox Farm Ocean Forest. They have been in the current pots about two and a half weeks.
When I first set them under the 600 watter, I put them way too close. Take a look at this picture. I think the damage seen is to the larger fan leaves is bleaching. Only the very top has this damage. The rest of the new growth is a very light green, with some yellowish tints. I'll get to that later. So, with this first pic, the damage to the large fan leaves seems to be bleaching. Thoughts on that?
With this next one, I return to the the coloring - all the new growths seem to be a significant shade lighter than the old growth. It isn't as pronounced when not under the MH...but still there is a difference. At first I thought this was still a result of bleaching - but what has grown out in the lighter shade doesn't have the "look" of the first picture. So, if the first picture is bleaching, then I don't think this is. The light is about 16 inches above the tops of the plants....maybe a bit more, maybe a bit less, depending on growth.
From doing reading, as this is my first grow, I think the discoloration is most likely nutrient lock out or a deficiency. I have very hard water here, at around 445 ppm out of the tap. That is generally what I've used. It's also of very high PH - above 8.0. In general, I must have the worst tap water in the world. Anyway, here's the second plant.
Tonight I gave a heavy feeding of distilled water. 1.5 gallons for each plant. Not really a flush, but not able to do a proper flush tonight and won't have a chance to tend again until Friday. They weren't totally dry and ready for a feeding...but I thought this might be a mini-flush. It was three times the amount of water they normally receive.
I've tried to include the relevant information...but if I forgot something that may be of use, please ask.
Based on the pictures and the descriptions, what are your thoughts? I've decided to feed only with distilled water from here on out. I figured I have another week or so of veg stage and another week or so of sufficient nutrients in the soil, but I don't really know. Maybe it is a deficiency...but I'm thinking it's more likely the beginning stages of nutrient lockout. Or perhaps it is still light bleaching.
I am truly lost and any help is greatly appreciated.

. Those plants look like Olympians compared to what some other newer growers have on here.
