2nd grow 1st diary

Start of week 4 . Everything is still growing strong. Deciding on removing a few more fan leaves. Getting fairly crowded. Buds are stacking nice. Hopfully they get nice and dense with some purple hues. Temps I am keeping fairly low between 67-70f but I can not get humidty under control it ranges from 65 to 70% , hopfully there is enough air flow to avoid any mold issues with the 2 fans. Mid-late week 4 update... This week I started seeing some leaf problems only on a few leafs. But I had this same thing happen first grow and it spread very fast as i couldnt figure it out. Im thinking it is phosphorus defiency as this ph perfect seems to ph my water to about 6.3. Anyway all 3 got a flush 2 days ago along with a feeding of cal mag only . Next watering going to feed as normal only ph it down to 5.8 and hope this fixes my issues before they get out of hand. I also defoliated a few more leafs today and yesterday. As you can see its fairly crowded. I was only expecting to grow 2 plants never thought that middle girl would grow into something so beutiful.
