Northern Lights Auto (Biochar Mix Soil)

WEEK 12 ( 24/2/2020 – 1/3/2020) 25/2/2020 - I took out the large oscillating fan and put the small one in its place. I ordered two more small fans. One will be positioned at the bottom. Another will be used for the drying tent which I've already ordered from Mars hydro. I placed one extension socket inside the tent,screwed to the middle pole holding the fan. Cable management is more efficient now. All plants are thriving well. Plant 4 trichomes are still mostly clear. Used yoyo to support the buds as the stems are starting to bend from its weight. Overall quite happy with the progress and quite eager to harvest. Molasses - 1tbs/gallon Micro - 1ml/L Bloom - 2.1ml/L Oxygen - 1ml/L 17L water. 4L for each big pots Molasses - 4.5 tbs Micro - 17mlBloom - 35ml Oxygen 17ml pH adjusted to - 6.5 Run off water pH - 6.7-6.9. Plant 4 - 6.4 26/2/2020 - Observed trichomes for plant 4 using digital microscope and macro lens attached to smartphone. I cut a small piece of the sugar leaf but not enough trichomes to provide proper assessment so cut a small piece of the bud measuring 1mm by 2mm (not a good idea and it wasquite painful to cut it off. Never to be repeated again for other plants) . With the macro lens I noticed a lot more cloudy trichomes than previously. Even several amber trichomes noted. But with the digital microscope, it appeared all cloudy. Strange. But I'll go with the macrolens findings as the image quality is much clearer. I am not very confident with the next course of action as there are 2 more big buds with mostly white pistils. Should I start flushing now or wait for another week or so. But since more amber trichomes were visible this time around, plus the buds are not packing up much any more, perhaps its a good time to flush before I miss the harvest window. Im not happy with how the buds turned out for plant 4. No uniformity and just looks plain ugly compared to the other plants. I wonder what is the reason for this. Would it affect the potency? 27/2/2020 - Supposed to water today but after collecting water, mixed with liquid oxygen and tried to lower the pH but I accidentally dropped too much of pH and caused it to be too acidic. Then used pH up to bring to 6.5 but it became too alkaline. Got frustrated and gave up. I'll just water them tomorrow. So stupid. 28/2/2020 - 17L water mixed with 17ml liquid oxygen. PH adjusted to 6.4. Each pot 4L of water and small pot 1L. Run off water for plant 1,2,3,5 - 6.8 -7.2 Plant 4 - 6.8. Surprisingly alkalinic. Not sure why. Hopefully after plain watering today, it will go back to normal range. Plant 4 is showing more amber trichomes. Mostly cloudy ones. Clear trichomes are still present but minimal. Its a good time to flush. Since the medium is hydro, I'll just have to flush for a week then harvest! Plant 2 trichomes have turned half clear and half cloudy. Not very confident of my findings though. I'll check again after few days. The thing with taking pictures with macro lens on a smart phone is the image can be really good but when zoomed in its quite hard to make out clear and cloudy trichomes. As you zoom in and it goes out of focus, clear trichomes can appear blurry and giving cloudy appearance. Maybe if I disable the auto mode and do it myself manually it would produce better focused image. 1/3/2020 - Plant 1,2,3,5 feeding with molasses, Micro, Bloom and oxygen. Plant 4 is just plain water pH to 6.3. Trichomes inspection for plant 4 revealed more turning amber. Plant 2 trichomes are still predominantly clear. Perhaps another week of nutrient feed before flushing. Plant 2 moved to the middle as the leaves look like it's getting bleached from light. More yoyos added to support the buds for plant 4. Overall plants are healthy and no signs of pests, gross malnutrition or other issues. As the plants are getting into the later stage of flowering, I noticed that the run off water pH is more towards alkalinic. But still within acceptable range for soil and hydro for plant 4. But plants appear healthy so its all good. Molasses - 1tbs/gallon Micro - 1ml/L Bloom - 2.1ml/L Oxygen - 1ml/L 13L water. 4L for plant 1,2,3. 1L for plant 5 Molasses - 3.5 tbsMicro - 13ml Bloom - 28ml Oxygen - 13ml Ph adjusted to - 6.5 Plant 4 - 2L of plain water mixed with 2ml of O2. PH adjusted to - 6.3 Runoff water pH - only checked for plant 1,2 3, 5,- 6.8-7.0.
