help! dead/dying plants.. i failed. can i revive them??

I have 17 ryders that will be 2months old in a week.. Everything was looking good untill a couple weeks ago.. Almost every plant is yellow and the majority of the leaves are yellow and drying out and dying/falling off.







I do admit that I have neglected their nutrient schedule.. :/ I have given them one or 2 feedings of big bloom and grow big when about a month ago.

I'm really scared I fucked these up.. I was really depeneding on them :[

IS THERE ANY CHANCE I CAN REVIVE THEM?? If anyone knows a way please let me know!! Thank you!

When plants are nearing the end of their grow cycle the leaves will fade and die off. Yours looks a little like that mixed with some improperly pH'ed water. When in doubt, flush it out, then give it a quarter strength feeding. Don't know how much longer you've got to go but it may be worth it. Hope I helped.

so is it still possible to revive them?

No, you cannot revive them. Once the leaf is dead, it is dead.

You have nutrient toxicity a.k.a. over feeding a.k.a. salt build-up.

You need to flush that media of excess salts and dial your feeding habits way back. I'm assuming you used a bloom enhancer high in P and K. If this damage coincided with the use of that supplement then that's the problem. If you have not used a bloom nutrient then you've just fed your soil too often with too much food. Incorporating plain water feedings when growing in soil is extremely important.
