Mayday Mayday Mayday Hydroship sinking

Not sure what this is, i am leaning towards heat stress but i need help to ID it.

try this.

whats your pH and ec? also what nutrients are you using?

Bro your ship is sunk.

What's ur temps again? How much u feeding? are you checkin pH? Not alot of info for anyone to try and help

Looks like your ph is out of whack.

Adjust to range 5.5-6.5

ph 5.5 @ 1100PPM via GH Flora series. temps in tent i am unsure of, my wireless moniter fell to the base of the plants, but one day i recall it reading 84, so at the tops of the plants it could of been 95+. This only affects the top portion of the plants, and some leaves have curled up (like a taco). i added some water to bring the PPM's down, since the PH goes down and the PPMs go up over time. which may indicate too strong a feeding, or the plants could be just taking so much water per day that the solution gets concentrated via evaporation/plant usage.
