Fast Buds Testers FF 6 - Mostly Sativa

Started the week off with a watering of the plant on 2/12/20 with 1 gallon. pH'd to 6.4 with runoff around 6.3 and up to approx. 30% runoff. Followed up with a feeding on 2/16/20 with 3 tsp Big Bloom, 2 tsp Tiger Bloom and I decided to vary from the recommended Grow Big feeding and only did 1 tsp rather than 2. I am starting to wonder if I should have gone with the extra tsp of grow big because she is showing signs of nitrogen deficiency and it seems a bit early for it to be flowering stage fade. The final feed for the week happened after a 4 days with no water which I estimate she needs every 3 days so she may look a bit droopy on the 2/16/20 pics. Runoff was again around 6.3 pH. Her counterparts in the garden have similar showings of fade but I have to remember these are a fast flowering genetic and should be finished 10-15 days earlier than the rest. This is very clear in her bud production as her stacking is pretty incredible as well as the bulk she is getting in the colas. With that said, the fade could be very on par with typical late stage flowering fade as that would technically put her 2 weeks ahead. Alternatively, the yellowing started on the bottom middle and this could just be a calcium deficiency. I do not believe I will give her any cal/mag in the next week as I think I will instead adjust the next grow to do a supplemental feeding of it sooner unless it takes a turn for the worse. Also some light defoliation of yellowed leaves as well is anything blocking on the top of the canopy. For being a Sativa dominate strain, I am really impressed with her bud structure and growth. I would expect her to look more like her garden mate Xodus with actually is much less of a Sativa leaning Hybrid (https://growdiaries.com/diaries/46090-xodu-grow-journal-by-jayann). The Xodus is much taller, spindly and wispy as opposed to this mostly Sativa who hands down has the most impressive bud structure, stacking and bulk. Again, I have to remember the fast flowering genetics of this strain and can not really make a comparison with the Xodus. I will save my judgement on that after everything has been harvested.
