FastBuds Variety - First medical grow

Going into week 5 I am feeling pretty good about how things are progressing! Unfortunately, the photos will be a bit off color going forward. I'll do my best to get them in natural light when I can. Blackberry has received enough LST to allow side branching to level with the shoot apical meristem and keep her canopy even with LSD-25's. Though heavier LST has left her less attractive than her tentmates, I am confident it will pay off once she fills out. Currently, she is showing the most prolific flowering with pistils already forming dense knots. Gorilla Glue is a truly beautiful plant that exhibits the healthiest/densest growth of the three; unfortunately she is almost 20cm shorter and has not shown any pistils as of this update. I am hopeful that once she hits flower, likely this week if other diaries are any indicator, her stretch will get her more in line with the others. Light LST applied like a tomato cage around her base has kept her side branching very close to the top. Once she gets there, I have a feeling she will be set up for a nice flower. I would like to do a run with just several GG phenos at some point. Luckily, I have 9 seeds left! :) LSD-25 is the well-behaved one of the lot. She doesn't shine quite as much as her sisters in terms of dense vegetative growth or prolific preflowers but she is steady, doesn't give me trouble, and I could easily see her being the one to provide a proper bumper crop. Her lower waist was also cinched up with plant ties, similar to GG, to encourage her side branches to train closer to the top of the plant. . I will wait for stretch to slow before applying Canna PK 13/14 but have started Canna Boost and will likely phase out Rhizotonic in favor of Cannazym starting with the day 29 watering. I'll try to post updates this week! Thanks for following along. UPDATES: • 2018/10/06 - Day 30 ○ Some very mild yellowing in spotty fashion on Blackberry and even less so on LSD-25. I suspect I may have had last night's PH too low. Forgot to check the gallon again just before feeding. Later realized another gallon mixed at the same time with same ratios was PHd way too low Into the red zone! ○ 2gal nutrient solution mixed @ 1000ppm, dispersed between 3 plants to correct root zone PH and EC. ○ Additional leaf tucking on GG and light LST on LSD-25. • 2018/10/07 - Day 31 ○ Height: BB = 66cm (Trained) | GG = 40cm | LSD-25= 69cm ○ 2gal nutrient solution dispersed between 3 plants. Inflow solution @ 930ppm ○ Additional leaf tucking on GG. ○ Blackberry is the most sensitive to fertigation in general and seems to be the first to show drooping after daily feeding. ○ LSD-25 and GG will readily absorb any amount of water in well drained medium. ○ Some mild signs of nitrogen toxicity in LSD-25 and BB. This is likely from the accidental low PH feeding on Day 29. Yesterday's flush seems to have corrected. ○ Light positioned ~ 23cm from top of BB. • 2018/10/08 - Day 32 ○ Height: BB = 73cm (Trained) | GG = 44cm | LSD-25= 76cm ○ 1 gal nutrient solution dispersed between 3 plants, 20% runoff achieved. ○ Inflow solution @ 1110ppm. Outflow solution @ 1987. ○ Gorilla Glue finally shows pistils! :) ○ Light positioned ~ 20cm from top of BB. • 2018/10/09 - Day 33 ○ Height: BB = 79.5cm (trained) | GG = 47cm | LSD-25= 86cm ○ Inflow solution Gallon #1 @ 900ppm - Gallon #2 @ 1080 ○ 1st Gallon Outflow solution: BB = 2105 | GG = 1807 | LSD = 2225 ○ 2nd Gallon Outlfow solution: BB = 1850 | GG = 1600 | LSD = 1840 ○ BB & LSD-25 suffering from early nitrogen toxicity. Corrective action in progress. • 2018/10/10 - Day 34 ○ Height: BB = 85cm | GG = 50cm | LSD-25= 92cm ○ Inflow solution @ 736ppm ○ Outflow solution: BB = 1725ppm | GG = 1680ppm LSD = 1767ppm • 2018/10/11 - Day 35 ○ Height: BB = 89cm | GG = 53cm | LSD-25= 100cm ○ 4 gallons evenly dispersed across three plants for tonight's fertigation. ○ Inflow solution @ 430ppm (PHd CalMg filtered tap water only) ○ Final outflow solution: BB = 1450ppm | GG = 1330ppm | LSD = 1391ppm ○ Hopefully lower ppm readings for outflow solution indicate nitrogen toxicity will soon be under control. Lessons learned this week: ○ Always flush coco coir reconstituted from bricks no matter what the manufacturer says about pre-washing. Proper prewash and initial buffering is paramount to a successful coco grow. ○ Always water to 20% runoff in coco and never let coco dry to the point it changes color. I was bad about this in the early weeks and paid for it with constant outflow ppms of 2100-2300 in week 5. ○ Always measure inflow and outflow EC. The HoneForest TDS meter I bought this week was $14. There is no excuse not to know your EC and having this metric earlier on in my grow could have saved me a lot of time and effort.
