This is why i only use pro-mix, because, then i know exactly what i feed the plant. It makes it alot easier to diagnose prablems. and if ur using sensi then it is NOT mag or cal deficny because it has all that in it.

Ibet if u flush flush flush. then wait a watering or 2 to add nutes. maby that would do it. Or maybe u have some sort of pests. that would also make ur plants look like that. maybe soil bugs.

Also, the way i know i fertilize to much is keep eye on leave tips. burn will start from there.

I still think your problem may be with the PH
While Nitrogen and Potassium run close to parallel in PH availability, if the PH goes to high (too much fertilizer in your case) then this locks out the Manganese a fair bit which interferes with your Potassium intake.
The leaves don't go yellow, so you automatically don't assume you have a Nitrogen deficiency.
Sometimes it's the trace minerals that are responsible for issues.
Here.... take a look

Chlorinated water was another possible, but I assume you fairly good water?
Cheers Jimmy.

I had the exact same problem. The guy that said heat stress was right. However, your lights might not be hot, but if your humidity is too low then they will still heat stress on you.
BUT also... I'll bet you're not getting them and fresh, outside air. They need some more Co2.
Anyway, read up on VPD (vapour pressure deficiency) and you'll see. Seriously... I went through two grows suffering this and fn around with pH and deficiency stuff when finally guy helped me solve my problem... with a humidifier and a muffin fan to bring in fresh air. It was that simple.

My water PH is 6.8. by the way sensi grow a+b are ph perfect dont think it is about deficiency or ph.I still think your problem may be with the PH

Your plants look like mines? and can u see 3rd pic leaves of middle part of plant are very small and curlly. And I dont have low huminidy its about %60.

This is what a girl looks like when she doesn't get enough Co2 in 4 weeks of veg and 9.5 weeks of flower. I pulled an ounce of her. She was NOT stripped or trimmed in any way. The leaves just turned yellow, dried up and fell off. You have to get fresh air to your girls.
Jus sayin...

Ohh... I didn't realise there was no fresh air exchange @_@
Stale air can do some head scratching things to plants, Ive seen that on forums and in real life.... fresh air is a must
Also, do you use RO, distilled or tap water?
Cheers Jimmy.

Lots of HVAC stores sell ph pens... like FW webb. They use ph testers to check the acidity of condensate from high efficiency furnaces/boilers

Fulvic acid helps increase the metabolism of a plant and is useful in that the nut burn threshold increases...the plants become tougher. Silica helps plants tolerate heat stress. By and large, people use to much nutrients. I definitely did,more food more flowers....seemed logical to me. Lockout, nutrient burn, and heat stress are so much harder to fix than any deficiencies. Raise the light immediately, mist them off with distilled water when the lights go off a couple times a night a night and cut down your ppms by 25 percent for the next feeding and 50 % on the following one. That is all.

Thank for enlightenment. Should I turn off light now ? cuz I am still in veg phase 24/0. they have 5 more days for flovering light cycle. And you say first feeding 3/4 strength second feeding 2/4 strength isn't it?
Thanks everybody for helping my babies. I am going to post result and pic a weeks later.
