First Grow Hulkberry

Nice week of growth. The girls are about 13 inches on average, D and L are taller. Betty definitely seems like a sativa pheno compared to her sisters. I found some brown algae in my tubs, I did some research and discovered I needed to cover my net pots to eliminate light pollution getting into the tubs. There were only a couple of small spots, I was able to remove it by hand. I slapped some foil on the tubs and made sure each lid was completely sealed. PH has been holding pretty steady and I haven't seen much drift at all. Towards the end of the week it struck me that the stretch is coming. I did some rough calculations on my current height and max height ill be able to have and I feel I should flip to flower by the end of the week when I swap new water in. Another week of veg and a stretch may be too tall with my lights. So I changed the water late on day 42, pulled some fan leaves and adjusted my light timer so when they went out in the morning they'll be off for 12 hours. I've left the MH bulb in for the flip to help control the stretch this first week. I read you can leave it for the first 2 to 3 weeks but depending how this upcoming week of stretch goes I may pop in the HPS during early week 2 of flower to get a little extra height if I think I need it. Was not ready to take clones, I may try to pull some on day 47 coming up, just a busy time of year.
