Plant height is becoming an issue at this point. Was forced to dim the light a bit,
as I was seeing some lighter colored leaves right in the center where the light shines the most.
The Holy Grail is doing some funky things. Big fan leaves are showing some purple. Possibly a phosphorus deficiency ?
Will try a flush with the Herculean Harvest which is a liquid bone-meal with a 0-6-0 NPK ratio.
