Hey from far away my plant looks quite good. 1st photo.
but inspecting closer I can say:
I have a small nutrient burn and my soil pH goes too low.
So I'm continuously fighting low pH with dolomite watering, here and there.
right now it is end of 9th week:
plant have a trouble with taking all the nutrients as it should, it seem to have too small "pot" "Air-pot 12,5 l".
It is Auto Skywalker Haze (sativa strain)
I'm aiming for big plant:1m high and thick.
now it has 68cm and it is widespread with many tops, so I believe it need nutrients to hold up.
IMO: next time need to use less potient soil, this one was packed with Nitrogen and it doesn't go well with pH
also need bigger air-pot.
What I don't know?
2nd + 3rd photo:
why newly grown sugar leaves got this strange burns and yellow spots
(suspected Calcium and Magnesium deficiency? or Phosphorus?)
Also why I got purple edge on new sugar leaves?
too much light?
I have TS.1000 (60cmx60cm 140cm tent). lamp height 30-40cm from canopy. 100% power. 18/6
I'm worry about foxtailing hope it will not progress this time. looks like there is quite a bit of stress in growth.
need to go up to 12/13 weeks with this auto. some tips? clues ?

thank you for insight.
I planned to keep her up to 12-weeks as this strain description tells me.
I have 60x hand microscope, trichomes still looks like cristal to me.
Most probably I will start clean watering/flushing this week
(week 10th).
You're so close to harvest that I wouldn't even worry about it. Cannabis will naturally fade or throw deficiencies towards the end of it's life since it's an annual plant. Also, you will trim off those leaves during the trimming process anyways. Looks like that plant may be ready to harvest now; how do the trichomes look?
