Auto Daiquiri Lime/ First Time

Looks like your about a week behind, judging from where my girls usual are at 4 weeks... I think from looking at your pictures, she's slightly overwatered... Let her dry out for a couple of days and then try to keep a thight dry/wet cycle... Good luck!

I prefer to have my LST training complete before flower, but you can still continue.. The end of week 2 flower is around your last chance to LST, before the stems thicken up, and force you to HST (supercrop) to get a desired shape.

Calcium. Not enough. pH is probably low that can't uptake enough. Can raise your pH or add cal to your next feeding

Well if you can't get a hold of a microscope, you can always go for the time recommended by the breeder. You can also try and look at the hairs. In most cases they will color and start to curl in the end of flowering. Though you should be careful not to touch the flowers since this will also cause them to color and curl 😉 In general it's also recommendable to when you think it's ready for harvest, wait another week or two. All these methods will help, but in the end a microscope will make your "harvesting at the right time" much easier 😊

not all seeds are created equal. When doing a pheno hunt you will pop loads of seeds and pick the best from the bunch. So when ordering seeds from seed banks you are basically doing your own pheno hunt. Some seeds will finish quicker than others even though they from the same batch. It is more than likely that your flowers will be ready before the breeders flowering time. Do you have jewellers loop or a magnifying glass? Take a look at the trichomes and see if they are milky or amber or clear. This is the best way to determine when to flush your plants. Happy growing!
