Plan tips deteriorating?

The tips of some of the seedlings that i transferred from Jiffy pellets to a General Hydroponics water farm began to die after i gave them the nutrients needed for the 2nd week of vegetative growth during their 2nd week of being a seedling on accident. The cotyledons started to turn light yellow then they started to turn a grayish lifeless color and then started to wrinkle shrivel up,I switched them to RO water at 6.0 ph and no nutrients but the first serrated leaves started to begin deteriorating as well. Some are surviving better than others and have began to grow their 2nd set of leaves but the first set seems to continue turning gray. Should i give up on them or what? i did this with 5 out of 11 blue dream seedlings, the other 6 are striving and i am having no problems with them in the Jiffy pellets.

No just keep on and either they will survive or they won't. But it's amazing how resilient a plant cannabis is.
