Second try, diary is starting on day 62,

OrriSakki She have reach the hight if 177cm, way taller than I ever expected, reason is mabey I started with another but got only one lamp, second one got delayed somewhere one the way from Amazon, it seemed to me the first one King Kush auto had almost reached final highed, then I planted this one, lamp never came, had to order another but in the meantime little one had to fight for the light and was very pushy, overgrow her older sister, I got 50 gr of dried buds of the old sister, way more than I thought couse my first time ever, didn't have lamp when I started, and I have no such things as green fingers, killed even a plastic 🌵. I took the older sister down before I wanted couse I saw how Mrs Biggy was growing and desided to give her all the attention, I have never checked pH value, ever, just put the ingredients in the pot, watered it, poked my finger in and exactly week later,( both times) something green came up, I don't even smoke but the butter I made from them sugar leaves from older sister scored 9.5 in taste, 6 in strength, only thing I know I did really wrong, and I knew it was wrong when I did it was not flushing it properly, but I know of experience of unsmokeble buds, course I was given 2 kilos of those 11 years ago, it was in big white plastic barrel with red lid on, I through it up on the attic, year later I was moving and going through things, then I found it, 2k of best weed ever, at least my friends I gave it to gram by gram (always waiting for something back) smoked it all, I know even worst taste ever can be cured away, enough of that, I would like to know when is good sign of best (or semi best) time to harvest, I ordered that seed and thought it would maybe crawl over 80 cm, but it's way further, biggest bud mabey 20 cm, I have noticed different between those two are the sugar leaves, older sister had way more of them, does that say any of the strength of the buds ??
