Preparation:
I have prepared the following nutrient solution for Week 3 -
650 ml of Aqua Flakes A
650 ml of Aqua Flakes B
110 ml of Root Excelurator
380 ml of MultiZen
40ml of Drip Clean
Ph: 5.7; DO - 9.1; Temp: 74 degrees
Light cycle - adjusted to 12/12 (4PM to 4 AM to coincide with night to help reduce power needed for temperature control)
Notes:
All plants are experiencing massive growth in terms of % change in mass. Some strains are quickly developing similar traits as their soil counterparts in terms of leaf patterns, vertical vs. horizontal growth, etc. I have noticed more compact leaf sets, with little vertical stretching so far. I believe this may be due to the light intensity and the relative distance from the light source. All plants are exhibiting signs of solid chlorophyll saturation, with notable new plant growth at the internodes. Expected dropping of the initial leaf pairs was noticed while the new sets took their place. No additional plant deaths this week. An unknown dark green organic material was noted developing at the base of the cubes - possible algae? I will observe for now as it does not seem to be affecting the plants.
Upon further examination under the microscope I have noted a limited spider mite infestation on the Blue Dream clones. Must have come from the mothers, but not definite. I have applied 1/6 oz of Azatrol per 32 oz RO water to all plants via foilar spray to control the infestation with the lights shut off to avoid leaf burn. I will check next week on new samples to verify control. No notable leaf stress or damage for any strain. Noted a substantially larger main stem on all plants as compared to their soil counterparts, assuming this is due to the distance to the light source and the intensity. All plants appear to be very healthy with no signs of necrosis or nutrient deficiency.
I am adding approximately 2grams of Organic Ph down to the reservoir on a daily basis to keep the Ph within parameters. This seems to be consistent regardless of the light cycle. I will need to install a Ph/temperature controller to the reservoir attached to a premix of organic acid and heating rod to ensure volatility of Ph/temp is minimized.
