Hi Eloyd, and welcome to the farm. Can I ask you to post this in the
Cannabis Infirmary? That way you'll have your own dedicated thread.
When you do, please include as much husbandry information as you can, including environmental parameters (actual numbers, please) as well as what the pH itself actually is. Saying "it's fine" doesn't help us help you, we need to know what it is, especially in relation to the media you're using and the strain itself. And I say this because
everything about that plant says it does *not* like the pH. Not enough to cause lockout, but still, it's not entirely happy with the situation.
Oh! Before I forget, you don't mention how you're measuring pH but if it's using a meter, make absolutely certain the meter itself is reading properly, too.
