Open sesame an epsomsalt when early flowers appear
Open sesame (FF) is 5 - 45 - 19 ! P is WAY too high! Unless you have rather advanced skills. DO NOT USE or you'll burn your plant shitless with P....It will yellow out from bottom to top and you'll have reduced yields and quality!
Never mix Epsom into soil.....You can mix some with water and apply that.....Still better to make a "Sweet Raw" type of supplement with it and use that properly then to add Epsom for anything except to correct an "emergency" Mg shortage.
De fan the hell out of it less leaves...more flower...carful not to much
Oh PLEASE don't do this ! This is a hotly contested issue here! We have an actual side by side, being done by a very, very advanced skills grower to prove the point that all you'll really get is smaller denser buds that have potency but little bag appeal vs. non defoliated......Leaves are the food factories of the plant! What happens when less food is available?
Dont spray a pest control of anykind unless it all natural...dont spray anything when it flowers
This is opinion! Form your OWN!
I have no doubt you will! The first time you get spider mites and you can't control them after a few weeks of Neem.
Outdoors is good if your in a climate where your plants can actually finish...
I started over 43 years ago. I wish I had the resources available today that you have access to! Get and read several books on the subject! I strongly suggest these..

Treat you plant like a normal tropical plant and find it easier to do.
If you choose the synthetic route -
Do NOT fall for nutrient makers telling you to start high P bloom foods at the flip in lighting times!
Continue "veg" feeds for 2 weeks after the light flip at the 3rd week mix the veg and bloom 50/50.
NO sooner then week 4 do you start 100% bloom feeds!
Follow this and get healthier, greener plants in bloom as they should be!
