I would say they were nuked.

Was this a overnight thing? Or a gradual thing?

what is the envio..

what is the envio..

it is a long guesing game if we don't know what is the soil,ph,strain...etc. etc.

lamp = 600wt "dutch poot"
air = rkv125 out and rkv100 in
temps range = 65*f -105*f
hydro r ph @ 5.5 and fed hesi hydro grow during veg (with baracade
and sensi zym)
same for flower but @ ph6.0 and hesi bloom
both hydros r unknown genus ,but belived to be afganica
proly p.o.g ,but soil grow is Cindy 99 ,none PH,d tap water
@ 7.1 -7.2 with floragrow/micr as feed
fyi ,i have over 10 grows under my belt all turned out very well ,till now ;/
last 2 have gone yellow on new growth ,then as that grows outwards it makes leafs curlup and turn yellow/brown
and plant stops growing

105F? that's the first thing you need to fix...

 

[MTF-Sandman]

^^Definitely...info on your nutes & PPM/EC would also be very helpful.

Damn, I freak out it I see the lower 80's...

Your temperature is way too high with 105 F, it should be 85 F maximum.
Are you recirculating the water, if so you need to use a different nutrient, for instance Canna Aqua or H&G Aqua Flakes. These nutrients are especially for recirculating systems such as yours. They will keep your pH and EC levels stable, which is very important when recirculating.
The symptoms of the plants look like a shortage of sulphur, but that is almost impossible normally. But could be related with the wrong nutrients you are using.

Peace

RGR ,fitting a rooftile to vent out of
and changing air sorce too
atm they r fed from opposite sides of the
houses sofets ,

What are the roots like? Water must have been damn near boiling with 105 degree temps.

 

[nocturnalG]

yeah too hot will kill em

 

[LaShY]

Heat Heat Heat!

 

[mattmantis_uk]

tile will be

105 *F ,not *C

 

[Brian1975]

What are the temps in water?? How do you cool your water??? If you allowed the temperatures to reach 105 degrees fahrenheit in that room and didn't have a chiller for your water, then there is your problem, plain and simple.

 

[mattmantis_uk]

Hmm ,but 1 is in soil and looks same
plus ,this started in veg stage wen room waz cooler !!?!
so ill sort temps out 1st ,then take it from there

 

[green michine]

Best of luck matt, but 105 is quite warm, even i would want to die in those temps.

best of luck matt.

 

[ItsGrowTime]

Ph is in 7.0 and up range is pretty bad too. Overall your environment needs a lot of work for growing. Getting temps down, getting ph down (esp. in hydro!), and switching nutes would be my first moves for the next crop. With those conditions nothing will live very long.

Cheers 4 the feedbax guys bax in 5-6 weeks

 

[harold]

too much heat makes plants thirsty... maybe you over fed them too with the extra waterings???

sad day
