At least two of those look sativa dominant, so the height is about right for this point in the year, that size pots. They should be starting their stretch soon, if they haven't already. My 5'6" indica has started hers.
I'm pretty close to lake Ontario here, so pretty far south. I was surprised that my girl started her stretch so soon, but a lot of the guys around here are seeing their plants start to flower early this year. Just a weird year for growing all around.
The tallest one looks like she may have started her stretch, right at the top there. But if this is your third grow in this area I'll bow to your experience. This is my first outdoor grow, and I stuck one girl right in the ground, and the other I've been bringing indoors at night, started her flowering June 15th. She just burst right in to flower, grew pistils during the stretch.
You don't really need to dechlorinate tap water, especially here in Ontario. My years of growing hot peppers, and my indoor grows have convinced me of that. No difference in growth between plants given rain water, and those given tap water.Medium: Promix HP (Peatmoss, perlite, lime and mycorrhizae added)
Nutes: Advanced nutes micro, grow, bloom ph perfect
PH of feed: 5.5-6.0
Foiler spray: Neem oil and insecticidal soap given twice, once 2 months ago and the second was applied a few days ago.
Tips: I always make sure i de-chlorinate my tap water for atleast 24+ hours outside before feeding. I feed everytime i water and use less than 1/4 to 1/8 of the nutes depending on how old the plants are. I find less is more sometimes because burn will only slow you down, feed little by little and look at your plants. Always water the pots until there is 5-20% runoff
I have yet to feed them more than 320ppm of nutes, usually stick with 100-200 ppm for most waters and do less or more if needed (My tap water is 70 ppm and is not included, so 320ppm of nutes would be more like 390 ppm for me using my tapwater if i used the meter)
