Shiva Skunk strain at day 39 question

I got some cuttings(plants actually) of some Shiva Skunk from a friend who had landlord issues. They were 2 months old when i got them and pretty large with mites. So i cut them back quite a bit and cut the mite infestation down with some neem oil and an avid application. Then I vegged them to about 10 inches tall and put them in flower 39 days ago.

This is supposed to be a 50-55 day strain and I was told that it was a fairly heavy yielder.

I was wondering if anyone here has grown Shiva SKunk and could maybe let me know if these girls look a bit behind schedule? With only 2 weeks left to reach the 55 day mark they look quite a bit behind schedule to me. Or very much less yielding than i was lead to believe.

I will attach a few pictures.

Specs: NFT system, ph between 5.6 and 6.2 (had a large ph swing while at work once that burned some leaves), running about 970 ppm with water starting at 70 ppm, they were under a 400 mh for 10 days and have been under a 1000 HPS for 29 days, They are showing signs of mites again.

The reason I ask is that I would like to start flushing soon if they really a 55 day strain. The flowers just seem very small and trichomes are very clear.

I'm no expert, but stress will make a plant take longer. They're not done until they're done (cloudy).

Your definitly right on that. Cutting back a plant takes wawy longer to mature but you did the right thing. And yeah dude i would start flushing right now (2 weeks) before harvest. Check the trichomes with a microscope or if you dont have access to that then check to see when the pistils turn from clear to a color on 60% of your plant or harvest when they are all brown/ red etc to have a more indica dominat high
