Multi Strain Autoflower

I believe they are about done with stretch. I’m watering about every other day. I’ve been doing 3 feedings with nutrients then the 4 th watering with recharge and silica all ph’d to 6.2-6.3. Everything looks healthy no nutrient burn. Really impressed with the chocolate skunk it’s the tallest and is loaded with bud sites. The devils cream is blowing up as usual this is my 4th time growing it and it never disappoints. The bubble bum is super compact so much so I moved it closer to the fan to make sure it’s getting enough air flow. It’s the shortest of the three ,but it’s going to have some nice super compact buds judging from the density of the buds already. Only time will tell.
