m0useanswered grow question 3 years ago Your diary is a bit different from others, Your plant is also big for week 1.
If this plant is a photoperiod its feeding can be increased from .5ec up to 1.2 if you really wanted.
With BioBizz its also advised you let the nutrient solution sit out 12hrs before adjusting the PH as it tends to drift down. ideal range for BioBizz is 6.2 in a hydro setup. in soil 6.4-6.8 is good.
Your plant looks a bit overwatered as well to me and could use some calmg maybe.
Best to update the diary once every week from sprout to harvest.
Good Luck!
