First autoflower grow- BLUEBERRY

Buds continue to develop and starting to show some crystals towards the inner part of the buds and leaves. Still growing upward a bit with an increase of 1" but it seems to be almost entirely the top colas elongating, and not the stems stretching more. Continue to water about 1 liter every other day and continue leaf tucking and defoliation as necessary, but it is very minimal. These girls are on autopilot right now and just need to maintain the conditions and water. Plant 2 had some older, smaller, leaves toward the bottom discolor and so I plucked them. I may feed with another round of fish bone meal in a week or so if it progresses, but not convinced of it yet Day 48 update: plants are drinking more water and watering with 1 liter every other day but might have to increase it if it keeps drying out this fast. Frost is devolving fast and excited to see these buds plump up in the next couple of weeks!
