6 weeks into flower, what do you think?

So as the title says I’m 6 weeks into flower (48 days since 12/12 flip) and was hoping I could get some feedback.
5 gal fabric pots, FFOF/FFHF blend, Sf2000 80°~82° daytime 68°~70° nighttime, RH 35~45%.
I’m going with a water, water, feed schedule. As of a week ago I was watering every 3 days, but moved that up to every 2 days.
I noticed leaves getting a bit dark from N so I cut my feed in half-I was giving 2tsp Tiger Bloom per gal (each plant gets 2 gal per feeding) and cut back to 1tsp per with the appropriate amount of Ph Up for range.
After cutting my feed in half the tested EC was 0.9 with a 456/560 ppm reading, is this too low even though the plant isn’t responding well to higher levels?
I’ve also got 1 random fan leaf with damage, thinking it’s wind burn (?) that singular leaf has been whipped by a stationary fan for weeks.
Pics 2-5 are from my Kosher Tangie, remainder are from my Frankenstein that’s showing some improvements

Lookin good

One of your plants looks more mature than the other........ Here is mine, also in the middle of week 6.
The color is off - I am still guessing on how long to harvest. At least 2 more weeks I suppose.

I wish I knew

Looking good! My guess would be at least 3-4 more weeks on yours-I’m thinking around the same for my Kosher Tangie. The Frankenstein has been a slow runty grower since the beginning, I have a feeling that one will be going much longer

Any thoughts on my feed/Ec situation? Am I better off staying with my low feed/Ec or should I try to bump it to around 1.2?
Also, any thoughts on that one wonky colored fan leaf, wind burn, light burn?
