First grow (white widow)

Lollipop yes, heavy defoliation, no. ALL of the plants energy to grow is made in/by the leaves. Less leaves = less energy being made = less potential growth (smaller flowers). Removing a large amount of leaves from plants that size would severely effect the plants ability to grow flowers to their full potential. The plant relies on those leaves to make the energy it needs to grow the flowers!

It’s natural for that to happen. What you are seeing is the plant recognizes that leaf as not producing so the plant is pulling its nutrients from that leaf to sacrifice it to feed other growth. I usually try to eliminate a lot of the bottom foliage to force everything up to the top part of the plant for increase bud production. Other than that I think your girl is looking great. Keep doing what you are doing I hope this helps.

Your plant is healthy. Don't treat it like foie gras. React to deficiencies and toxicties as you normally would, but don't get smart and try to force feed it more. Genetics is primary factor for size of resultingn colas - assuming good health an some attempt to max out DLI (daily light integral, read wiki). However, if you grow out too many branches/colas, the overall size of each will suffer whiel the yield will rmain relatively the same. DLI (light) determines potential yield along with genetics. So, if you capture the light in the entire area (specficialyl the top of leaves fill entire area) and limit it to 2-3 colas per sq ft, you'll maximize yield and should have decent sized buds relative to the genetics at work. More colas than that just means more trimming effort, smaller buds, more larf at bottom and same yield ... Embarassingly, it took me too long to figure this out. I remember asking some people if this effect was something that occurs after i grew some plants with fewer colas than i normally did and seemd to notice this trend, and was met with incredulity when i brought it up. The 'experts' i asked in a large chat channel here essentially said more colas = more buds and that is far too simplified relative to reality. That set me back 2 years before i found much better info about this and going to be more dedicated to implementing it in a systematic way. (check out cocoforcannabis dr photon's corner.. the comments to these articles are iffy, but sometimes the conversations are worth it too).

Lid closed in a cool dark area is ideal, no longer then 4 days like leftovers. airtight if possible. If there is room in the fridge its good. Or freeze it and let it thaw out on the soil line in summer like how some people water orchids. Air stone can help like @Organoman suggested, it will also promote aerobic bacteria vs anaerobic and that can sometimes be a bonus. To @UBU's point, chloramine does not off gas, but you can destabilize it with UV or Vit C aka ascorbic acid then it can be off gassed. But there is so little in the water its not going to affect the grow greatly. Cannabis does not seem to be overly sensitive to CL from my experience with it, unlike some carnivorous plants, they can be really picky. Good Luck!

those leaves are the energy source for your plant they absorb the light and send that energy thru to the buds I only reccomend removing leaves if they are underneath and not getting hardly any light or they are blocking the buds from recieving light and stopping air movement which is important to combat bud rot etc So in your case its not a matter of too late but just not needed imo

Continue to feed about a week then flush for a week to then harvest

your plant doesn't look like it has a toxicity or overfed in any clear way. carbs feed microbes and do nothing directly for the plant.. this will have very limited effect at this stage of the game. Are you seeing amber outside of the top colas? Make sure not to look at trichomes on the leaves. I'd guess you ahve 7-10 days left and could go water-only if you wanted. Don't do excessive runoff though, the plant still needs building blocks (law of conservation of mass). to ripen. The thing is, what if you have 15 days left? Now, you'll have a plant 80% yellow when you still need photosynthesis to power the rest of the ripening... so, don't be afraid to change course if the canopy takes a nosedive too soon and you don't see enough amber/cloudy to your personal preference. flushing just to flush is not a good reason. There should always be a reason behind it... just as blindly defoliating isn't beneficial, despite common belief. This observable effect is no different than people believing that stress is a cause of heartburn.. it is not, yet some still cling to that belief. Even doctors in the 90s long after it was known not likely to be true contineud to spread this false belief. Molecular chemisty is beyond the resolution of human senses. I was lazy and gave water only the last 7-8 days of last grow. Got a fade, but only at very end. I did this because i was lazy not beacuse i think it changes the taste of the weed. A plant that had long-term toxicities is going to taste like shit even if you flush it. as long as you avoid overfeeding or react to it quickly when it does start to progress, all is well. Your foliage does not exhibit a problem relative to stayge of life cycle (entering senescence at this point.. some damage is inevitable and depends a lot on genetics)
