So as stated in the title I'm growing for the first time and I'm worried that my plants may be too cold.
Each plant is lit with two 23W CFL's under a clamp light and I have white film hanging around all the plants.
I have them in Miracle-Gro Organic Choice potting mix and I give them tap water that has sat open for 2 days to help rid the chlorine.
I usually water around 1 liter per plant whenever they're dry a couple inches in, so every 4 or 5 days or so.
The temperature is low 60's, high 50's day and night but it gets a bit warmer with the lights on.
The two tall plants, the ones that are mostly having the problems are Sour Diesel. The smallest one is a poor strain of Purple Haze and the next smallest one is Pineapple Kush.
Not only am I worried about the leaves yellowing/turning purple but I also have much lower yields than I was expecting. I'm 7 weeks into flowering.
Do I need more light? I was hoping I would be able to grow well with just soil and water, I don't want to mess with hydro or air.
Here they are the day I switched the lights from veg to flowering:
And here they are yesterday:
