C4 Automatik Outdoor

I use today my organic fertilizer taps 6+2+6, I use it for all my plants. A colony of ants used one of my Pepper to breed lice and a couple also got on my weed. I hope I was able to remove all but one or two 3 or 4 days ago they are in the flowering phase a little longer than they should but with the cold temperatures. C4 is said to be very resistant and can apparently withstand a lot of cold. xD
