Cream Cookies novice grower

I really feel like I am learning SO MUCH with this grow, heaps of things I could improve on next time. 😺 Day 28 - I fed her a 420ppm nutrient solution, and as I was watering her a fair bit got on her leaves. I shook it off her but a few drops on her lower fan leaves were stuck. So I grabbed the droplets with my finger and smeared them into the leaf. Big mistake, next day the leaves were all burnt! 😡😲 The upper fan leaves that I didn't touch were fine, the leaf tips were fine also. Day 30 - Plant really looking happy now, growing nicely and stretching up towards the light. The 4th set of fan leaves still 3 pronged (has grown cotyledons, then true leaves with 1, 3, 3 and 3 prongs). The 5th set of fan leaves is now visible as a bud in the center, and I can see that this set has 5 prongs. So was likely the stress that made the first sets of leaves 3 pronged. Day 30 - I really want the plant to be BUSHY to take advantage of this small light and surround it, so I decided to try FIMMING today! The middle bud was at the perfect age for this so took the opportunity, I hope she can handle it. Happy to sacrifice a bit of yield to get more buds closer to the light for a more consistent quality. If you think that yield is more important and I shouldn't do this, here is a fact for you, over the last 5 years I have gone through about 30g of bud with me and one friend, we have some about once a month or two. So yeah I don't care about yield just quality 👌. Day 34 - Female preflower showing! Shit this means she will be into bloom soon, and still so far behind where I wanted her. Researched on the interwebs and found that I could still have a good 2 weeks of fast vegetative growth at this point. I realised my last feed was only 1/3 strength fertilizer. Time to feed her a decent meal, GO STRONG OR GO HOME! I fed her 5L of pH 5.9, ppm = 775 - with 20ml of Canna Rapid combined A&B
