Maybe potassium def? Get a second opinion, they're gonna want more info, lighting...feeding...nutes...ect.

Potassium deficiency...prolly causing calcium and magnesium lock out...

Awesome! Thanks!

I'm 4 weeks into flower. I had a couple days where my intake/outake air shut off during lights on. Temps spiked to 105°F, on two seperate days. The second time the temp spiked, the plants transpired like crazy. This happened going into second week of flower. It seems ever since the spike in temp those two days, really screwed things up. I started with 20 plants and 5 plants started wilting, eventually dying after the temp spikes. I lowered temps and they still wouldn't recover. I'm thinking the root zone got too warm in the 4 " rockwool cubes, causing root rot potentially leading to lock out?

Thanks again for the help!

If your roots aren't too bad , hit them with h2o2, it basically scorches the surface of your roots and causes new root development to explode. I had root rot on my last crop because my air stones got clogged(rookie mistake) and they got starved of o2 plus root rot. I about cried. Still got some nice buds though.
