Yellowing leaves

Hi guys and girls im growing purple stardawg and in week 7 of veg. They are clones and we're doing well up until a week ago they starting to go a lime green. Ph is currently at 5.8 to 6. There on mills nutrients a and b also have had supplement cal mag once or twice a week and one maybe 2 feeds of sea wees the entire 7 weeks. There's 10 of them in 18ltr pots with 2 600w hps lights and 2 480watt quantum boards. My lights are raised as far as they can go around 4ft away it can't be insufficient lighting ph has allways been 5.8 to 6 max. I'm feeding nitrogen supplements. I'd say it would be too much yo blame pests as everyone is affected evenly over all plants. The older leaves at the bottom have remained there dark green colour. I keep saying it's too much light but is it really? Any thoughts on this? Thanks

Pictures are definitely needed if you want more than a guess.

they look a little lighter than in the actual pic. Thanks.

next time take a picture with a bluprl light on

I’m not seeing anything that would concern me honestly. Perhaps someone else will. Nice plants.

Thanks for your reply and kind words. They were alot darker than this and have gradually been getting lighter. I dont know whether I should flip to 12/12 knowing there not as green as they was but then I've never taken one out the tent an taken a picture till just now, and it does infact look alot greener than inside the tent with lights on. I've never had this happen before.

looks like you might soon get a magnesium deficienty. some leafs are showing yellowing between the veins.

Thanks, thats funny as I've been given supplements twice a week. Ino the pH ranges between calmag both are up and down so I may need to try changing the pH on different days. Thanks for that as I didn't even notice that issue. I think il leave it till weekend now to flip I really didn't want to veg much longer as there a very decent size. Just concerned with the yellowing and now this, not sure what to do tbh.
