Hi guys, I'm having problems with coco that i never had , almost a month that tey're showing what seems to me overwatering symptoms, but I'm not sure and I may use a little help
All the plants (4 melongum dr.underground- 1 pre98 bubba PCG) show same signs, pale color, purple tips, extreme curling-hooking leaves, extreme slow growt or no growth at all...they seems to be getting less pale in the last days and i see some new growth but very slow, but leaves are still almost round shape..they all look like this now, till a week ago color was eaven more pale

Its full coco, the plants were absolutely healty the first 4 weeks in 1 liter small pots, transplanted them in 3 liters and moved to a new cabinet for flowering, it started getting cold ad had some problem keeping stable temps (nothing crazy, 15° celsius min) for a few days,here the problems i mentioned started showing, at first i tought it was ovarwatering, so I tried giving less and eaven getting the coco almost dry, but nothing changed so I'm not sure about that...I've flushed with tap and i'm giving less nutes (my tap comes very hard, they were on a light feeding anyway).. I've raised the temperature in the room and added an heat mat under the pots...they seems to be getting better now but slowly and i should have switched a mont ago....
Didn't find the problem but if they get better now it probably means the flush helped, dont think it was overwatering, I watered coco way more than in this case...I wrote this anyway because I'm having the same problem with new sprouts....they seem to be drowning but the coco is just moist, not wet or soggy at all, and they're starting getting pale too...

Sorry for the lacking english, peace
I've had this same exact issue occur to me. I never changed how I fed the plants but I noticed that when I transplanted and put them into flower the very same day they would get the clawed leaf for about 2-3 weeks then return to normal. My grow room was also around the same temperature as yours.
What I did to fix my issue was to not transplant and switch to flower on the same day and I also put in an electric oil heater to keep the grow room between 64-68F (17-20C). After I started doing this I never got the clawed leafs every again.
