Added a liberal amount of Biobizz-Grow, GO Diamond Black, and Marphyl Marine Phytoplankton on Day 3 of week 2 as yellowing and deficiencies were starting to occur. Growth was moving quite fast and past the edges of the solo cup so on day 7 transplanted into 5 gallon fabric pot after a bit of pruning. Using Pro-Mix HP as medium and added extra myco about every couple of inches and around the roots before transplanting.

Grew the growth tips out a bit I had chosen to start the mainline with and then topped above and pruned everything below. Watered on day 3 with compost/nutrient tea which was brewed for 3 days and consisted of Bokashi Pro Gro compost, some blackstrap molasses, Marphyl marine phytoplankton, Biobizz grow (beet vinasse), Diamond Black (Humic Acids), and CaMg+ (Calcium/Magnesium/etc.) Growth started picking up again at the end of the week after the top and mainline.

Upped amount of bio grow by 0.5 tsp/gal. Letting soil dry more in between waterings to try to establish a larger root system quickly. Continuing training to maintain an even canopy and the mainline to establish 12 colas and 4 potential clones to be cut before the switch to flower.

Started bottom watering at 1/3 total volume. Continuing LST and tying down to promote a bit more of sideways growth on side branches. Lightly defoliating every 2 or so days to remove large leaves and give more light to growth tips. Preparing for the switch to flower and will give one more nutrient filled compost tea at the end of week 7

Started growing mainlined branches upward and continuing light defoliation every few days. A small snap occurred when bending down stem but used a plant tie to push it upwards and it quickly recovered. Next week (week 8) will be the final week of veg and the transition to flower.

Fed compost tea on day 3, which was brewed for 3 days and contained listed nutrients along with 1/3 cup Bokashi pro-gro compost and 1 tbsp/gal of blackstrap molasses. Showed noticeably thicker and even quicker growth a day or so after. Switching to flower environment on day 1 of next week (week 9) and will remove much of the larger leaves and ones which are blocking light to bud sites then.

-This Granddaddy is a hungry one so I’ve added slightly a bit more bloom this week. -Defoliating larger leaves and leaves blocking bud sites every few days. -Tying down the majority of the branches to keep an even canopy.

Added compost tea at the beginning of the week which was brewed for 3 days and contained all listed nutrients, 1/4 Bokashi Pro-Gro, and Blackstrap Molasses as a food source. This Granddaddy is a huge feeder so I have been giving it a bit more bloom than usual.

Happy with the defoliation achieved but will still be removing a few leaves here and there blocking bud sites. Gave bokashi compost tea at the beginning of the week. Continuing with larger feeding regimen than normal as she is a heavy feeder

-Sucking up the water and is quite a heavy feeder. Gave it a bokashi compost tea at the beginning of the week and removed two lower bud sites that were hindering airflow and not getting any light. -Even though GDP is an indica, the stretch on this girl is very much sativa like

A huge feeder in her entire life cycle and a quick vegger. Took well to bending and training and always sprung back quickly from a defoliation session. I was hoping nodes would have been closer and it was a more compact plant but I am very happy with how it turned out.
