Well it's my "second" grow but the first time we harvested way to soon. But this time already looks WAY better (think cause this time I used Fox Farm last time... I don't even remember the name) I NEED to mess with my pH meter cause *sigh* I hate to admit it but I haven't been checking EC or pH. I will probably try to do that today I've just never used one before and I got a high tech one so I'm overwhelmed. Any tips for calibration and taking the readings?
