WYK MONSTER

I'm not seeing anything that you should be worried about in the video or the screenshot. The leaves look healthy to me. Most of the tips pointing down are on the sides, so they're probably just pushing against the tent when it's all closed up. The leaves will twist to reach the light the right way up, so it's perfectly normal. Personally, I think you're all good - good grow! :)

I think you made a mistake here. If you want to raise EC in the substrate you need to give EC higher than substrate to get desirable EC. Also increasing intervals between waterings can help even if you maintain the same EC. When substrate dries out EC is rising. But this can lead to salt build up, and can slow down the plant because it will struggle to find water while having issues with excessive osmotic pressure. So if you have low EC in the substrate and you want to make it higher, increase EC of the solution at least till desirable EC, and water with 10-25% runoff. If you have a high EC in the substrate and you want it lower, decrease EC of the solution so it is less than desirable EC. It will dissolve the excess of nutrients in few watering events. Another way is to feed every other watering.

the red is senescence or colder night time temps... nothing to worry about.. aslo could be genetics. if temps drop below 68F it can exaggerate this coloration. if it's not moving up from bottom, it's possibly k-deficiency. but usually this would be more damage on the leaf tips. if it is moving up from bottom, it's N. seems a bit limited.. 2 bad looking leaves but the rest is small potato damage. verify pH but this doesn'tlook like a pH issue. make sure calcium is not too high as that can lock out K. can always use manic botanix nutrient ppm calculator to track individual ppm of each nutrient. over time you can learn what is too high or too low with high precision.

Looking at the pictures and diary you will likely land around 4 to 6 ounces. They are not done yet so it is hard to say for sure. Plus keeping her fed right and ph cN play a role. I would reduce nitrogen as much as possible in bulking for future help.

Looks fine to me. Sometimes early browning of pistils can indicate pollination but these flowers are too late in flower to go off that. It's possible she has seeds, wouldn't surprise me. Some strains it's easy to tell if they got seeds but for others you won't know until you're breaking it up and putting it in the grinder. Honestly I wouldn't worry about it. Seeds really aren't the worst thing.
