Sweet Nurse CBD Auto

First real buds and calyxes are starting to develop. White pistils and some coloration on the leaves. Initial trichomes are starting to appear. Plant is very bushy and internal bud sites are not getting as much light as they need to develop fully but anything exposed to direct light is developing nicely. Beginning to run into a nutrient issue likely due to too low PH. I was watering with PH'd water but not watering to runoff which I believe led to exceptionally low PH (under 5.0 in the run off readings). I also lowered the light to within 8 inches and caused some light burn over the next several weeks which the plant never really recovered from.
