CFL 1x1x3 complete newb

This is my first female out of a handful of unknown bag seed I've collected. Absolute beginner here so did a lot of reading online and came here for some experienced advice on how I'm doing.

Grow space is a tiny 1x1x3 cabinet and I decided to do 12/12 straight from seed as well as LST it to minimize vertical space. I'm using 4x23w 3000k CFL bulbs for lighting. A computer fan on a variable power supply for exhaust at the top and passive intake for fresh air at the bottom.

I never thought to keep track of dates nor could I fully tell but I think she's about 25 days into flower. Early into flower I misdiagnosed a defiency and over fertilized but quickly figured it out, flushed and have been smooth sailing ever since. I got some litmus paper and my tap water looks to be around 6-7ph and it seems to do fine, I set it out for 48 hours before using. I fertilize every other watering and mix my nutes depending on what I think she needs. About 2 weeks ago I took 2 cuttings and both have rooted. One looks haggard, the other happy as can be.

So the million dollar question is, how am I doing?

Yellowing is a bit worrying, but the newer growth looks good. I know she's 25 days into flower, but how old is the plant from seed? I'm doing a photo grow next round, so I'm curious.
 
Pretty sure the yellow was from over fertilizing causing toxicity, lost a handful of leaves that shriveled up and died too. Now I know for next round.

From now on I'm logging everything. I'm not exactly sure how old she is but I believe she was planted around mid April.

Looking good. Hope you're still feeding nitrogen, thay is exactly what those flower feeling yellow leaves indicate.
 
Update approx day 42 flowering. Any ideas whats wrong? Been giving them 2-7-7 fert every water which is approx every 4 days. I just got some blackstrap molasses and have added a 1/4 tsp per liter of water.

Yesterday I just gave her 1.2L water with 1/3 tsp molasses. All water is around 6.5ph give it take my meter isn't very good.

I'm not expecting much from this one just looking to learn. Did I over nute, under nute? Any suggestions?

the bud doesn't look bad, the fans do look like they yellowed early
usually, that means underfed, but hard to be absolutely certain
the plant has sucked out nutrients from the fans, and given them to the buds
on a positive note, bud should be nicely flavored, provided the genetics are ok
see many a complaint of foul tasting over-fertilized flowers

again the buds look ok, however the leaves are curled upward, brownish and yellow = nutrient and or water deficient.
 
So the concensus is that I've been undetfeeding it which is why it's eating itself for nutrients. I'm glad as I've read it's better to underfeed than overfeed.

Thank you for the advice going to up the nutes on the next watering and check back with an update.

Unbalanced diet. Too much P and K in comparison to N. They are very N deficient. You want a ratio close to 3-1-2 pretty much start too finish. High P and K bloom foods only cause issues in a peat or coco based soil.
 
It is for container grown cannabis. Just look at your plants, they say it all.
Thanks for the advice. At first I was going by what others said online but I'm slowly learning to read the plants like you've said.

I'll give it a more balanced NPK diet for the next feedings instead of the 2-7-7.

Thanks for the help this is my first lady, had 2 males before her so this is purely a learning experience, if I get any yield at all I'll be pleasantly surprised.
 
Gave her a full watering with 15-5-5 and 1/2 tsp per liter molasses so we'll see how that does. I've read molasses is approx 1-0-5 so that brings it to 16-5-10 approx 3-1-2 ratio.

I've also got 2 seedlings in the cabinet so their lives should go a little smoother than this one's.
 
Well the yellowing and necrosis definitely slowed down but is still happening. I don't think I have enough air flow to the roots, only used about 10% perlite to 90% dollar store potting soil when I transplanted into the final container. I'm wondering if a couple drops of 3% hydrogen peroxide per liter of water is safe/beneficial? If yes can it be mixed with chemical nutes/molasses or should it be used as a flush?

Also in the last day or so a lot of the hairs went from white to orange going to check the trichomes later.
