Does this look like it is too cold?

I took the temp of a 5 gallon pot of coco and it said 58. My highs and lows are always over 60 under 80. My feed goes in between 5.7-6.0 with 25% nutrient solution every time with runoff. I decided to run my exsaust tube right back into the room. But that wont help at night. I turned up the forced air, gas heater, 2 degrees. I also just got done insulating the floor with a layer of cardboard and elevated every plant with a dish or milk crate. I was thinking about watering with 70 degree water. A mistake I made a couple times was being lazy and letting the water go in too cold.

these pictures are of 30 plants, 9 strains, all between week 2-6 of veg. under 1000w hps + 166 watts of cfl

I'd love your opinions. Thank you.

25% nutrient solution every time

They lack vigour not from the cold but from under feeding. N def, time to use 100% dose.

Let me think on that a bit.
Good point.
Thank you.
Does anyone else agree?
I always feed less but with every watering. They always lack vigor though too.
I am so sick of not getting a nice easy grow. I watch all these newbs get ridiculous beginners luck.
Pisses me off.

Yeah I think 25% is a bit too cautious with plants at this size, give em a real dose. I grow in my basement and you have the right idea of elevating the plants off the cold floor. No beginners luck lasts forever and the sooner you encounter and learn from your mistakes/problems, the better grower you will be.

Yeah, they are big enough to handle more than baby-food.

Don't get too concerned about all these numbers and your temperature. 58, 60, 80 pH 5.7-6.0 with 25% nutrient solution every time. 30 plants 9 strains? So what? yer gonna get next to nothing at the rate you are going. meh.....

Your plants need way more light and some food.

I read h3ad's thread for a long time last night. He runs 100% coco and uses 6/9 ml of GH every watering and waters every second day. Simple enough.

I watered 4 of them with 6/9 ml's of GH. I hope that works.

I'm all about numbers.

Lots of numbers in your thread too.

You do look like you have a cool temp problem. The lack of food isn't causing your droopy leaf issue. That would be the cold. I have encountered this issue before. Try and warm up those roots.
