possible light overdose-please view pics

hey ya'll, got a hell of a problem. started some lowxak47 autos. germinated and put seeds into jiffy plugs with r/o water only for two weeks. normally it takes about 3, but this group got their 3rd set of leaves faster. so the jiffy plugs were put into 3" rockwool blocks and placed in the flood tray. then the 1000 watt hps in a fresca sol water cooled housing was put over them at about 12". they were flooded with just water r/o. within 2 days of the light being on24 hrs they had started to bleach. so the 1000 was turned off and a 600 hps in the fresca water cooled housing was used at about 24-30" above.they kept getting worse. as of now there are only two t-5 6500 k above them. not sure what is happening but i think it was too much light too soon. my question is if that is the case, will they rebound? given their current state should they be given some nutes and if so ppm ?

Yes that is light bleaching you need to back your light off when you put them under the 1000 again

thought so. am I doing the right thing at the moment?

Yeah it was good to put them under the t-5's. I would start feeding nutes also, start low and work your way up. What kind of nutes are you using?

dutch master gold. gave them a feeding of 190ppm of that last time they were watered wich was friday. havent seen any improvement

gotta get this right. autos only veg for bout 3 weeks so its crucial not to make mistakes like this. is there anything i can give them to speed the recovery?

thats how mine looked in a toxic tent,but you are not useing a tent so it is probably light bleach

i do have some advance nute b-52 left, thought about giving them a little

Any info on bringing theese back to life would be greatly appreciated
