Pink plants after going from hps to marshydro ts1000

Hi guys,My autos are starting week 3 I swapped out hps for led and they have like a Reddy pink I think it due to shock of the cold as the led anit as warm as hps. Do I remove my exhaust to keep heat or isit best to keep exhausting the stail air ? Any ideas would be great

They are sitting around 24.C which I think is low to be honest

Is it primarily on the stems and underside of the leaves? I grow under a TSW2000 and I had several plants I moved under it blush on me at first. The plants I started under it did not.

No conclusions, I just ignored it.

Yeah it's the same as you described. Did it slow the growth or affect the plants in anyway and did they go back green after while or stay red

Hi - LED lacks IR greatly so you wanna keep ambient temp higher (30°C) and throttle down the vent out to match its pull (in ccm^3/h) to the lamps wattage (actual draw from the wall) best using a step transformer or maybe your vent out already came with a built in throttle....

So I got the temp back up its sitting at 31.C but I have no air curicleation so I mite have run the exhaust at 5min on 10mins off on a plug timer or will i run into more problems with the temps fluxing up and down constantly. Its the easiest fix as I have timer laying around

the exhaust has to always run otherwise the carbonfilter won't work and there will be smell.

in veg the air circulation isn't that critical but in flower you really want to have the whole air around the colas moving to prevent water condensating in the buds causing budrot. this is especially needed when the lights go off, as there is a temperature drop which could cause condensation

Do you think a reptile 35w heat mat will help as they are pretty cheap and plug&play. It idea with would be put on a timer have come on and off once I've sweet spot keeping temp at 30.C with all fans running. I need a plug and play method if you have any ideas . Thanks kass

Yes so if the growroom ambient temp is too low then you need to get additional warmth to both roots and leaves - in order to keep the plants metabolism high (its also important during the nightphase).
The heating mat could do that for roots, but for leaves I'd order some IR lamps.
The basic problem with convective heat is that the air gets removed constantly by the outtake-fan, but the IR radiation actually releases its energy first upon coming in contact with matter (your plant's leaves, in this case)
