Hi PH.
Plants are looking great and good luck with flower.
I have some AI seeds I got from buydutchseeds, They say on their site AI is a cross of Afghan and Northern lights. I don't think there is any skunk in the mix.
I have been light feeding cause one of them were sensitive to the nutes and it burnt but now has the best looking buds lol. Its about 79 deg at top of canopy
