day 29. plant is doing well, responding to nutrient lights and others well on last week's progress plant is experiencing some calmag deficiency, so i dial back the light to 20/4 day 30. water level fall quite a bit since last reservoir change day 31. topped with RO water, 1 quart, pH to 5.9 haven't checked on the ppm and pH of reservoir, but water level is low spread some leaves and braches out to fill the closet more nicely day 32. growth is vigorous. nothing significant noted day 33. topped again with another quart of RO water. pH to 6.0 pHed to 6.0 because last time the water in reservoir on day 28 dropped to 5.3 just to counter balance the pH fluctuation day 34. noticed some new shoots from lower branches tucked some leaves that block those sites day 35. top sites starting to going yellow ish on late veg and it started to stretch a bit for a day kinda time to flower maybe?? but i haven't noticed any enlarged calyx only some but none actually bursting out hairs/ pistils water level is realllly low, my roots actually prune itself out quite a bit found some bits and pieces of the roots in reservoir later, and lateral roots dries up i mean its good so it wont grow much more i have my light bolted to the cabinet, cant move and only about 2 foot away from the canopy day 36 noon: chaged reservoir to new nutes guess what: the remaining water on week 4 nutes come back at pH 4.9 ouch. ppm is 565. great nutes carries over from last week, 600ppm pH 5.8 plus calmag changed the light schedule to 12/12 hoping to stunt growth a bit. aint much space to work with gotta defoliate lower growth later this week
