Feed or just water, am 1 week away or 3-4?

Hi All, appreciate any advice you can give. I stuck some seeds in pots about 4 months ago for giggles, and I noticed some little hairs about 35 days ago. Thought holy hell and started to nurture them a bit more. Greenhouse at night, chasing full sun on days, feed with organic during veg and sulphate of potash during flower . Turns out ive got 3 females of unknown strain, pretty sure they're are two stubby little indicas and one sativa. Im battling to pick the right timing On one indica, hairs are just starting to go red, bottom leaves are yellowing and I think trichs are going cloudy, but its bloody hard to tell, thats the first three shitty photos. If this looks a little cloudy, and about another three weeks to harvest, and I can wind back feed to you guys, Im think im on the right track. Other two pics are the other two.

I know enough to be dangerous but have forgotten more than I knew. Any thoughts/feedback would be good. Cheers

Feed till the end

Thanks gents, what's your time to go estimate based on those crappy photo, till the chop?

The last pic has a long time to go. 4-6 weeks. About a joint or two worth.

Cheers 2835. Growing in a cold climate with unknown type, and such a late season plant has thrown my timing out. The last one, the taller sativa is the highest yield, the two smaller ones look super leafy but frosty as all hell, ill give then about the same 3-4 weeks give or take. Appreciate the comments
