Need Some Advice

Hello. This is my first grow. I have 4 plants in soil (2xSuperLemonHaze feminised, 1xBigBud feminised, 1XLsd autoflowering). I will be grateful for advices and comments about subjects which sorted downside.
1. I finished 8. week. Feminiseds look pretty well, but autoflowering take longer than feminised to flowering. It says 8 week period seedling to harvest at herbiesshop, but it only in preflowering phase at 8. week. I can see pistils but very thin. I didnt understand why it doesnt become ready in 8 week. It looks like autoflowering will be ready at same time or later than feminised ones.
2. I gave nearly everyday (if they dont dry out at every 2 day) water at 8. week. Every first watering without fertilizer second watering with fertilizer. I use Biobizz as fertilizer. Do i gave fertilizer less than enough?
3. My light is Kingled kingplus 1500w led above 40-50cm of plants. 1,2mx1,2m (4x4) grow tent. Is light good choice for my plants?
4. I started to troubling with odor control although carbon filter and started to use Onagel in tent. It helps but is it really working for 4-6 weeks not sure. Still troubling with odor and will be thankful for advices.
5. It's hard to reach soil for watering because of leaves. Maybe is there easier metod for watering or useful equipment?

1. don't even follow the guidelines the companies give you. it's just that; a guide line. doesn't mean they will finish in 8 weeks despite it says 8 weeks. im not too keen on auto's but for feminised/reg seeds it's the same issue they say like 60days or w.e. until harvest but thats just bullshit numbers. it's ready when ITS READY.

2. look up signs of over fertilizing/what happens to cannabis when you over fertilize. just my 2cents but if your feeding full dosage and doing water, feed, water, feed. every 2 days that is too much food. if you feed very little it can be alright imo i did an experiment where i fed every single watering which was a 3 day rotation for me. i went from half to about 1/8th to 1/10th strength of fertilizer. in the end plants did well but if i didn't fix my feeding schedule early on it would of been worse. i would not recommend imo measuring nutes all the time is annoying try it out for yourself if you like. i do feed, water, water, water, feed. plants will tell you if your under feeding as well as over feeding.

3. kingplus imo is alright but you can get better. i bought the KingPlus 2000w it worked good but when i bought my HLG quantum boards the difference is fucking INSANE... $220 lights vs $500 lights ( what i paid at the time ). work with what you got and learn only reason i bought the lights were cause my dad was complaining it was blurple and people associate it with drugs despite you can grow other things under um.

4. look up Lollipopping it might be what you are interested in. if your risky look up Schwazzing ( it's when you defoliate the entire plant ). your in flowering so make sure you take that into consideration. i personally cannot recommend these to you during flowering not this late since im inexperienced in later phase grows when it comes to pruning. i would suggest you prune though of some sort. you will get pop corn buds, it lowers your RH due to more air flow. if your still not wanting to do any pruning at all for w.e. reason attach a garden hose to your watering can on the nozzle. water it that way i've seen people doing that of course the nozzle is the single spout ones not the big fat ones with bunch of tiny holes in them.

Just my 2cents. of course. it's all just about learning, trial and error for the most part.
