Looks like multiple deficiant nutrients, hard to be certain but looks to be lacking maybe magnesium, some phospherous and maybe even a little potasium for good measure.Maybe a shot of bloom juice?

if you've had them under low power lights for 1year maybe they could do with a blast of high intensity light and some stronger nutes to revive them a bit?

thats a guess mind

THey look like it's a mixture of both not enough lighting.......

Your dosages are confusing me.....

So how often do you feed them and the dosages and how often?

 

[spacecadet]

i been feeding them 350 ppm 6 days then i flush with plain tap water on day 7 i will try to feed them 500 ppm every other day and flush on the non-feed days with plain tap water as for the lighting i will try to add a clf or two as soon as i can get some cash

 

[MynameStitch]

every 6 days? or you feed them for 6 days?
SEe that is where I am confused at I don't understand what you are telling us.......

Normally you are supposed to feed every week, honestly I would flush them plants out sounds like you fed them too much too often .....

What size pots are they in?

Use 2x the amount of water to the size of the pot they are in for a proper flush.

well i am growing in pure coco so i feed them 350 ppm every day for 6 days then i flush on day 7 with a 1/2 gallon plain tab water and i repete the 6 days of feeding and one day of flushing and i got them in 4" pots
