Assuming your in soil:
First start out by giving them a seed tea to prepare them for monster growth in flower. Here's a tutorial of how to do it.

Then start by giving the Aloe Vera water and freeze dry coconut in the mix. After several waterings of just this mix and one week before going into flower give them another seed tea.
Top dress with this recipe :
Apply one Alfalfa SST 3 days after switching to flower
Take 2cuFt of Earth Worm Castings (Make a barley sst w/ flax ground in when when grinding the barley SST and add to water and spray down the EWC first) then once damp add
1/3 cup Neem seed powder
1/3 cup Karanja cake
2/3 cup crustacean meal
2/3 cup Insect Frass
1 cup Gypsum
3 cups oyster shell flour
1/2 Cup Basalt
1&1/2 cups of dried comfrey - if you have it.
Mix all of that into the EWC and apply an even 1 – 2 ” layer on each pot.
Give them another topping 6 weeks into flower. Ambessa Organics and Dragonfly Earth Medicine have some premixed teas that you can brew to feed between aloe coconut water. Also it won't hurt to give it 1tsp of Epsom salt per gallon in the third week and 7th week of flower. Especially if it's a an OG.
