Jaffa Glue Pie - Outdoor

Start of week 11(week 7 of flower) Buds fattening up nicely. Noticed some purple on a few of the leaves today, this could be a coincidence but last night was the first night with the carbon filter and extractor fan as the smell is starting to be rather pungent. Im starting to drop out all the nutes this week and will begin flush at the end of this week. Will probably flush with only PH levelled water for a week, even though with coco it doesnt need to be that long, i just want to squeeze all the nutes from the leaves and work through as much chlorophyll as possible before harvest. Update 29th - plenty of purple leaves now - would be concerned about a phosphorous deficiency if this was earlier in flower but im about a week away from finishing up so this is expected. will begin flush in the next couple of days. Little disappointed by the lack of growth in the buds the last 2 weeks, quality looks good though.
