Need help plants dying with 24 hrs

Hey I have a problem with my plants I have not figured out. They started to droop 6 days after flowering started. Then die within 24 hrs from that. Not over or under watered. Not sure if shocked from light being on 100 percent immediately after flip. I have now lost 2 plants to this and worried about mor dying. However started shortly after using bud explosion, however only used 1/4 dose per gallon. Pictures of 24 hr period. Yet other plants in tent seem to have no issues at this time picture also sent of another plant.

Ph 6.5
Grow medium Coco and perlite
350w Mars hydro led
MEGA crop and bud explosion
Temps at 21 degrees c
12/12 lighting schedule

Thank you for a quick response I have been watering them about 2 litres every 24 hours, so I should give a lot more water to them then that.
 
It's 90 percent perlite 10 percent coco
Dude it is crying out for water
I agree that is what I originally had thought but soils was moist. Other plants recieved same amount of water as them and are doing much better. My two smallest plants were the ones that have died on me. Here is a picture of one of the larger ones of same plant genetics.

With a 10/90 coco/perlite mix you should be feeding multiple times a day.......plus your pH is way too high.........should be around 6.0.

Coco basics:
Feed light nutes daily to substantial run off using a pH around 6.0.
Never give plain water.
Never let it dry out.

Ditch the bud explosion.

check out coco for cannabis. Give you a lot of helpful information on coco. I use a 50/50 mix with an automatic watering system. In my opinion it is almost a must have in a coco setup. unless you have time to water them multiple times a day everyday or use bigger pots
 
Thank you Tyler I have taken your advise too and ordered a automatic drip system. I have never used one so what would your timing schedule be for it.

You have to play around with it a little bit but my first watering is usually 2 hours after lights on then do for waterings spaced an hour apart on your last watering is when you should be getting your 20% run off so ends up being a little bit more water than if you watered all at once. But you will need some sprayers along with drippers or just sprayers only I currently use the floraflex matrix I have some pictures of it on another thread. And make sure you get a timer that is adjustable by seconds I got mine off Amazon. Another important thing is to make sure you use some H2O2 or beneficial bacteria for your storage tank and make sure the water temp is at a reasonable temperature.
 
Thank you everyone for the advise I have grown many plants outside with no issues for underwatering when growing in the same mix. Though this was my first indoor grow in a tent. This had been extremely helpful. Also Tyler I say your pictures and that looks like a great setup. Do you think is will work for now with a drip only or will I need to immediately get sprayers too.?
 
I have been looking at automatic watering systems but I think I will build one for next round. Wife is retired so I am making her do the watering during the day.
