The lower leaves on the Purple Punch in front are turning brown, what could this be? I am using Easy Boost pellets by RQS as nutes, water is ph'd to 6.5 in BioBizz Light Mix.

What is the ph of your run off? If you are not getting 20 percent or more each watering then there is the issue. Salts from fertilizers are left behind. They will alter the ph greatly in substrate from top to bottom. Like 6.5 in but 4.7 out is a example from my previous experience with it. It will also cause nute burn and deficiency in areas. Good luck and happy growing. 🌲🌲🌲👊
