First time growing

Hey ! Another week had passed, the royal dwarf and the easy Bud are now 65cm and stoppen growing. Tga royal ak is at 75 cm and she’s also at her top i think. The buds are starting to grow in volume and when opening the tent i get a Nice Smell 🙂. But The leaf problem is still there.. i hope i can make it till the end! I tried flushing( dont know how much water i need to poor true them) and now only gave bloom and Some green sensation. Any othter sugestions? Also the royal ak seem more yellow/ green then her 2 sisters. I need to be honest , i am a bit worried . Still Some weeks to go. See ya next week!
