And in those pics, you can see curled up leaf ends and more some tips that are more tan than yellow, which indicates a slight burn or ph/lockout issue. Very healthy plant, but if your runoff was 6.1-6.3, your yields would be more impressive .
I had severe leaf issues on my last grape slurri I ran, buds were beautiful, frosty and unaffected, but come to find out my estimates on my ph were way off and that run. Now that I invested in a good ph meter. My plants are even more robust than they have ever been! Not saying you can't get good results outside of optimal ph ranges, just stating that your results can be improved by also keeping ph in the optimal range. Just because you don't get bad results.... doesn't mean you can't get better results.
