Hi Guys,

photos link as i cant attatch

Fairly seasoned grower here with no clue whats going on.
I think i have a temperature problem due to the climate of my grow room but i have changed the temperature to be much higher and the plant still seems to be deficient or unhappy with something. one opr the other i cannot tell. Please can i ask for some advice on what you think the issue could be from my picures?
Grow environment
Lighting:
24hr 2x Spider Farmer SF1000 at about 2 feet away from the canopy
Feed:
I have just started feeding (yesterday) @ Generative Period 1 from the attatched grow schedule. (32ml coco a+b, 25 cannazym, 5 rhizotonic, 32 ml canna boost.) before using this solution i was on vegatative phase 2 until very recently (28ml a+b, 20 rhizotonic, 25 cannazym, attached file canna coco feed chart)
PH:
5.8-6 tested using a calibrated bluelab ph pen....

RH and temp:
40-60% rh
15-24 Celcius

Can anyone lend a hand in giving me some direction towards a resolution as im clueless!?

Many thanks

Real noob here, so what i say should be taken with a huge grain of salt. How long has it been getting that cold? I have never grown autos but i have had cctv cameras messing with my photos before because of the infrared lights. I understand a quite a few people use 24hr light with autos but i have always been under the impression that plants need to sleep. If it were me id get an oil heater in there and maybe 18/6 light schedule. I could however, be talking out my arse, im sure someone will correct me. Good luck bro.

temp would be an area of concern to me, as a rule i never left a plant go lower than 19c and typically keep my tent at 24-26c regardless of light on or off. Im a coco grower too, can;t comment on your feed really as i hand feed in 12 ltr fabric pots. in veg i typically run 1.5ml a and b per ltr of water at 5.8Ph(i dont measure EC). and in flower that would be up at 2ml usually.

Thanks for getting back to me; i have included a heat mat and a dehgumidifier to bump the temps up and im at 21.2c now!

Do you think this is the bulk of my isse?

Thankd for mentioning your feed; im not sure if i should make my nutes less potent due to my plant already looking deficient??

Hey @GronkLeague, that doesn't look like a temp issue but more of an overwatering/feeding issue. The low temps are low but not enough to cause much issues other than slow things down a little. Your water is way too cold and I wouldn't be watering anything of it's sat at 11C as you will stop the plant from feeding for a short while.

Also, when the temps are cooler and you're dealing with issuez, 1.8EC is way too high. Only give them that EC is everything is optimal. I would drop that down to around 1.4EC and I would also give them a good flush with some flushing agent with plenty of run-off to correct any buildup issues.

The clawing and sagging of the older issues on top of the immobile nutrient disorder you've got going on looks like lockout

[Hmr81]

along with the temps i would tend to agree with Seymore, looks over fed very dark green. My water/feed would be at like 15-19c usually, cold feed really slows stuff down. I'd flush with plain water at 5.8PH and adjust my feed to be a bit lighter. no idea on EC reading as i dont use it.

If it were me id get an oil heater in there and maybe 18/6 light schedule.

I have read on 1 or 2 sites now that autos will produce more buddage on 24/0 lighting schedule. Right or wrong feck knows cus i dont grow them.
