New growth... spindly & curled under leaves! Help diagnose..

[lampost]

I'm having an issue. All plants looked healthy until about 2 days ago. Now on most plants the new growth is VERY spindly... super thin leaves that don't look healthy AT ALL. Also, some of the leaflets on the new leaves is curling under. Lastly, growth has slowed to nearly a halt! After 18 hours in the light I can't even notice a difference. Before this happened I could see a plant grow 2-3 inches over an 18-hour period.

PLEASE HELP!! No one is responding to this thread in the plant problems section so hopefully someone has some ideas here.

Additional info: 1000W HPS, Soil (FFOF) with 10% perlite added, these are clones that were transplanted 10 days ago, good ventilation, temps are in range but fluctuate from 60-80 between night/day, watering with distilled water when I can but also using tap water with a pH of about 8. Not feeding at all right now as I've heard FFOF can keep plants well-fed for about 3 weeks. Plants are in containers that are slightly too big... went from dixie cups to 8" pots (~1-2 gallon).

I'm hoping that this is a PH issue. I don't water them frequently, but when I do I give them a lot. Since they're in pots that are a bit big, I'm guessing the water stays in there for longer. So, you have pH 8 water that isn't draining very fast. Do you think this could be the issue? I'm going to get pH Down today, so if this is the issue it will be resolved soon.

Also, could heat fluctuations cause this at all? The grow room is not insulated well, so when the heat kicks off it cools down fast. But when the heat kicks on it heats up fast. So, the plants have temperatures that fluctuate more than I'd like them to. Even in the light cycle it can fluctuate 10 degrees (70-80).

Anyway, I hope some of you guys have some suggestions. My plants are not growing at all!!!

60-80 degrees is fine.
Are these autoflowers? They look like they're already trying to bud.

killerweed, thats what i thought it looked like to me, but wasnt sure, so im not going to reply on guess work. He said he waters a lot because of the big pots, which might have made them water logged. So, now roots are not getting any air, he used 10% perlite, maybe needs more?
I might turn the plant upside down to see if there is water cought up in the soil, just hold plant with other hand so it dosnt slide out:thumbsup:

yea a big pot needs to be watered less if anything, i have 2 gallon pots that get watered every 3 days, i say give it a couple of days and the growth with turn
to a normal shape

Well you have had a lot of different issues in the last couple weeks. My opinion, and it is just that derived from the pictures, is that it is possibly:
Too much water
too little light
too much nitrogen

Yes I have. It's my first crack at this, so had a barrage of questions. I appreciate the responses for sure!

It's not helping that I've got a few different strains going. This happens to be Mr. Nice. It actually looks a lot better now.

I'm not sure exactly what the problem was. Pretty sure it's not over-watering as I let them dry out too... when the clones first went in I only went like 4-5 days. There's a 1000W 18" from this plant so I don't think light was a problem either. Once I started pH'ing my water correctly things appeared to get better.

I find the FFOF is too hot for freshly transplanted clones. I mean, they'll end up getting healthy, but almost all of my clones got some fucked up, burnt, and twisted leaves when they were young. After a week or two they took off! So, yeah, I think FFOF is hot for clones. I'll cut it with Light Warrior next time and then just use straight FFOF upon transplant!
