Preparation:
I have prepared the following nutrient solution for Week 5 -
950 ml of Aqua Flakes A
950 ml of Aqua Flakes B
380 ml Bud Xl
40ml of Drip Clean
Ph: 5.5; DO - 9.1; Temp: 72 degrees
Light cycle - 12/12
Notes:
Growth trend has slowed as new bud development is readily evident. Plant phenotype heavily influencing growth patterns and reaction to nutrient supplements.
Avg height - 9"
Avg width - 9"
Given the stage of development, I am revising my estimates for a final height of approximate 12" (down from 14"). Light source proximity is still a concern, but does not seem to be having an adverse affect on overall plant health and growth.
Nearly all strains exhibiting pistil development and calyx formation at the internodes and colas. (pictures attached)
I have noticed the return, albeit to a lesser degree, of spider mites on a few of the strains under the microscope. I will apply a foliar remedy again this week (2nd application) to curtail the infestation.
Noted some strains exhibiting signs of nitrogen deficiency (slight) at the upper internodes and top cola. I will increase the base N nutrient additive to compensate and monitor closely.
Observed increased reduction in DO available in the reservoir towards the latter end of the week, where measurements were showing levels in the sub-2.0 range. I have tripled the O2 aeration with the introduction of a new bubbler and have added a recirculation pump to increase reservoir water movement and agitation. This will help ensure consistent DO saturation and reduction-oxidation reaction with the nutrient base to help with consistent Ph balance.
Observed significant root mass at the base of the cubes, showing signs of good health and overall saturation of the cubes. Discontinuing vitamin B series root accelerator.
