Extreme underwatering - are my plants dead? :(

[silloroy]

Hi guys
Im shocked, devostated.
I have 4 plants, day 6 of flowering.
Aperantly yesterday i didnt check them carfully enough and today
when the lights turned on - 2 of them look absoloutly dead. feel like crying.

I just watered them with nutes and sprayed 0.3ml of REVIVE.
PLEASE tell me if they even stand a chance - or is it over for them.
Thanks everybody

wow !! , so did you forget to water them , when did you last water them , ?

the guys here will ask you to check your ph and your full grow set up .

 

[Graytail]

Heck no, they're fine!

They'll lose all that lower growth but the tops will be fine and they'll love having drenched pots. You'll see a healthy growth spurt after this.

It's not a good thing to happen, but it isn't fatal.

I agee with graytail

I concur with Graytail, water them thuroughly and they will rebound. You may not lose all that many leaves.

And now (if you lifted 'em) you know how light they get before they're dry.

It's a lot harder to recover from over watering. Go easy on the nutes while they're recovering. You'll get great root growth if you let them get dry (but not this dry ) one more time before the flip (they look close) and then keep them from going dry during bloom, when the pot should be filled with roots and can consume the water.

Some of this may be obvious - jus' sayin' ...

Thanks everybody, you made a brother happy.
i watered each 1 liter of water with a reduced amount of nutes - 0.2ml sensi flowering, 0.1 b52 and 0.1 revive
i hope 2-3 from now i will be able to update with a healthy pick of all 4
cheers

Paddy guessed it!

While you're here, can you read this: How to Ask for Grow Support

And fill in all the requested information? That way we can go over your setup and offer suggestions if there's anything else we can help you improve.

First grow, indoor
my setup:
60*60*160 cm HOMEBOX grow tent - I know its small for 4 plants...next time ill grow 2
strains: 2 Skunk#1 feminized, 1 Northern lights feminized, 1 Afgan kush regular
they were growing for 53 days, currently flowering day 7
light: 250 HPS + 65W florecent
grow medium: soil and coco mix
nutes: sensi flowering A+B, B52 and revive - 0.2+0.2+0.1 per litter of water
pest: organic pest control spray once a week
temp: 25-30 (thanks to the AC, in our summer without AC it will get to 35)

*yesterday they were already looking better cant wait for lights to turn on to see them

Why does everyone magically skip the PH question when I give them the link? lol

Gotta answer everything brother. The PH question is a big one.
PH of grow medium?
PH of water?
PH of water/nutes?
PH of runoff?

You'll be able to train 2 plants to grow real wide in there, and could potentially produce what you'll see from 4 plants on this grow.
Your lighting setup should work perfectly for 2 plants too.

How far are the lights from your plants?

What is the soil:coco ratio? What % of each are you using?

Pot size?

Ventilation?

Humidity level?

Did you have bugs/pests in the past, or is that just preventative?

How often do you water?

 

[silloroy]

dont have a PH meter...ill get one soon
how far: 15-25 cm
coco ratio:dont know :\ its a ready mix from the store and it doesnt say on the bag
pot size: 5 galons
ventilation: centrifugal fan ak-100, connected to the COOLTUBE hosting the 250 HPS light + 2 six inch vents
humidity: 40%-60%
pests: i had signs of little holes, since i start spraying bout a month ago - their gone
watering: every 2-3 days

Bellow you can see pics of the 2 underwatered plants 24 hours after watering:

QUESTION: look at the soil - its dry after only 24 hours! the other 2 that were watered the same time (but didnt suffer
from underwatering) their soil is still moist. i guess the 2 that was dried were very thursty...
SHOULD I WATER THEM AGAIN NOW?? OR WAIT?

These are all 4 together: the 2 front ones are skunk#1, the 2 in the back (that were underwatered) are Afgan kush and Northern lights

 

[silloroy]

Another question: should i prun all the lower leaves that didnt bounce back from the dehidration?

 

[Graytail]

Top growth looks great! They're fine now

Yes, you might as well snap off all that limp stuff - it's toast.

And hmmm ... the watering. I ran 6 gallon pots in a 4x4 with a 600W hps with a small blower and 4 inch flue, and mine needed water every 5 days. They'd usually take 3 quarts each time. I have this 540W (draw) Intelligent-Gro panel now and they're not using as much. Your plants are bigger than I run, so I'm thinking yours go dry in 3-4 days. Did you lift the dried-out pots? Hefting them is honestly the best way to gauge whether they need water or not. Between that and the first stage of wilt (if you can check them during the day) you learn how fast they're drinking.

If there dead yes of course.
