Northern Lights Auto (Biochar Mix Soil)

Week 5 ( 6/1/2020 – 12/1/2020) 6/1/2020 - Light lowered back to 18 inches from canopy. LST adjusted. The leaves appears healthy just quite dry especially plant 1. Is it because of under watering? Light too close? Fan too strong? For now my diagnosis is under watering. It is getting so much bigger after all. Light too close maybe but the other plants are doing OK. We shall find out tomorrow. Otherwise just a little stressed about the rate of growth. The preflowers are getting more prominent. I should change my nutrient feeding to preflowering after the next cycle of plain water. Based on other growers, I'm just about the same actually. Thinking too much about it is not doing me any good and I might over do something. Chlorine test strip just arrived today and managed to get the Panasonic water filter tested out. The chlorine test showed 0 - 0.1. Which is fantastic. But the TDS meter showed 37, which is surprisingly the same as the unfiltered water. But the unfiltered chlorine water definitely shows the highest in the range of the chlorine test. Run off water tested and shows within the range of 6.1 to 6.5. Pretty good. Maybe a little acidic. The 6.1 was from plant 4 I think. Which is Coco mix mostly. Quite consistent with its grow media acceptable pH level. Micro - 0.7ml/l Gro - 1ml/l Bloom - 0.5ml/l 3L/5 gallon pot x 4 =12L + 1L =13L water Micro - 9.1 ml Gro - 13 ml Bloom - 6.5ml Liquid O2 -13ml 7/1/2020 - One of the small fan is lowered down while the other one remains in the same position. The timing of the fans readjusted to 6 hours each. Generally all plants look much better than yesterday. So it was under watering after all with the previous concern. Soft guard 2ml in 1L water applied to all plants. Soft guard is chitosan olligosaccharide and its supposed to increase the immunity of the plants. PH adjusted to 6.3. Quite surprised to learn that the soft guard solution is quite acidic. After mixing noted the pH was 4.8. Had touse the pH up solution for the first time. 8/1/2020 - Fabric pot is supposed to be better for the root growth because of better oxygenation. But I noticed that every time I water, it will seep through the side of the pot and a lot of it doesn't even absorb through the soil first. I initially thought that's just the normal run off water.So all these while, when I water not all of it is absorbed first. That's why my soil dries fast and I have to water everyday. Other growers have mentioned the need to water very slowly and using water sprayer to be more effective. That's when I thought of the water sprayer I already have which I previously used as pesticide. But using that is too risky. So I just bought a 16 litre water sprayer. Gotta try it tomorrow. And with the long nozzle it would be much more convenient to water without carrying out the pots every time to water. 3L each 5 gallon pot watered with 3 L of water + liquid oxygen + liquid silicon . 13ml of oxygen and 13ml of silicon added to 13L of water.PH adjusted to 6.3. 10/1/2020 - Micro - 1ml/L Gro - 1.5ml/L Bloom - 0.7ml/L 2L/5 gallon pot x 4 = 8L + 1L = 9L Micro - 9ml Grow - 13.5ml Bloom - 6.3ml Liquid O2 - 9mlLiquid silicon - 9ml Ph adjusted to 6.5 11/1/2020 - Philips dehumidifier fixed inside the room but outside of the grow tent. It's just more practical to leave it outside for tent space efficiency and heat generated from dehumidifier. The two China brand dehumidifiers used earlier are basically useless. They were just generating more heat inside the tent without effective water extraction. 12/1/2020 - 1L each pot of plain water pH to 6.5, then watered with nutrient mix. Micro - 1.5ml/L Gro - 1ml/L Bloom - 1ml/L Sio2 - 1ml/L O2 - 1ml/L 2Lx 4 +1L = 9L Micro - 13.5ml Gro - 9ml Bloom - 9ml Sio2 - 9ml O2 - 9ml
