image.jpeg This is my third attempt at growing this strain, I believe it's grapefruit diesel with strong stativa genetics (bag seed from a friend). It is a very fast grower and always shows signs of what appear to be over or under watering?! All my other 12+ strains have had no problem am I missing something here? I also wondered if this strain needed more than tha 10mg per gal cal mg? Anyone with experience with this strain I would greatly appreciate some advise!
