A brief summary of some beginner questions (first grow). Take a look at my diary for more info. English/German answers preferred.

1) it's a little odd that they look shiny/glossy but also paling... it's a contradiction of symptoms, lol. other pics in diary don't look glossy, so maybe just an illusion in the picture. Since it is in the central areas, it could be from slightly too much light, but i'd wait a bit longer before adjusting. Definitely want to be sure before reducing light. 2) more times than not it is inevitable - genetics or LED whatever... It can also be a sign of low phosphourous, but you'd see other symptoms. More times than not this is simply genetics and if it's predominantly occurring in the petioles most exposed to light, even more reason to ignore it. 3) Lolipopping requires some familiarity with where you expect well-formed buds to form. You may want to be conservative about how much you prune off down below. It helps to understand how much stretch remains and have an understanding of the depth of good nugs you can expect given your light and environment. Extremely shielded areas are safe to prune off. instead of going for as many tops per sq foot, consider sticking to 2.5-3 colas per sq ft in future. This gives you good penetration of light without sacrificing any canopy area. should get deeper 'better' nugs. On some genetics i see aweoms bud down 18-24" before it gets larfy. That takes a special plant, but shows you the variety that is out there in growth patterns. others are stocky and bushy and removing too much axillary or lower growth will only hurt yield. don't think this makes it "focus" on the rest of the plant, because that's not really how it works. 4) does it have a toxicity that's turning into a catastrophe? if not, no reason to flush. you can fix any toxicity with a minor adjustment to fertilization ratio/concentration. If you want to be lazy at the end of the grow, you can give water-only for thleast 1-2 week. this willmostly have to do with how heavily you fed up to that point. If in soilless, shouldn't be feeding too heavy and you don't want to give water-only for more than 5-7 days, but some potting mixes and fertilization methods may allow for 2 weeks of water only. just make sure that canopy actually lasts until the day you harvest... photosynthsesis powers everything, not just cellular growth. Those molecules that need to be built to form trichomes and thc/thca? that requires energy in the form of sugars formed from photosynthesis. Hindering that ATP et al production will only reduce outcomes, not help them. Check out the growing guides at cocoforcannabis.com. They will greatly aid you avoiding vast majority of "bro-science". Dr photon's forum articles are awesome too. the rest is a typical marijuana site full of misguided beliefs and anecdotes as well as trying to sell you shit constantly, lol. But, those guides are solid - not just for growing in coco.

PS - you’re in week 3 of flowering. All of my advice assumes you’re growing photoperiods and not autoflowers. Best of luck on your grow.

1. Not yet but further progression may warrant looking into. 2. Cal mag deficiency 3. Yes, to focus the energy on the top colas. 4. Upon milky trichomes Best of luck with your grow.
