Purple Lemonade Auto

Good week, plants are growing very well and pretty quick. hoping the buds turn purple soon, seems to be getting a little purplish or darker at least. been watering at 6.5ph and feeding every other day or 2 days. Tried topping for the first time on my plant still in veg, topped it early in week 2. Also did some light defoliation to the first 2 plants. I ordered an air filtration system too, i’ll be installing that this week as well.
