The Agnostic Church 01

Target Vapor Pressure Deficit (VPD): 1.3-1.4kPa As you can see in the pics, the yellowing of my leaves and the halt in bud growth is showing us that the nutrients in my living soil have run out. My yield is going to be hurt dramatically. It is completely because of a dumb mistake I made. I wanted to do a 50/50 mix of soil and perlite, but without thinking about it enough, that means my 5 gallon pot of soil is really only a 2.5 gallon pot of soil. KIS Organics recommends to use a 7 gallon pot for a full run, so you can clearly tell that I completely undershot the amount of soil to use. Full-on noob mistake. I almost can’t even blame my inexperience, but I was so focused on improving other things in my tent that it was easy to overlook. I’ve also been out of town most of the last few weeks so I couldn’t spend much time trying to correct the situation. I am hoping that I will be able to finish this run without chemical fertilizers so I am doing a full Recharge routine, and might possibly do a compost tea if I can find the time (thanks @TheBudWhisperer for the recommendation). I am not using Mammoth P currently, even though it is for phosphorus during flowering, but that it is because it is known to kill other microbes, and right now I need the full battalion of microbes alive. All in all, I will have to say this is a learning experience. So in the end, even if my current plants die on me before full maturity, it has been a positive experience. It is also nice to know that the Autopot system works, just so long as your living soil has enough nutrients to last a full run or you are using chemical fertilizers. While the plants did have enough nutrients, they grew with tremendous vigor. The improvements I made in rate of watering, humidity, lighting, and circulation made a huge difference. RECAP OF THE GROW SO FAR: Target VPD for the week 1-2 seedling cycle was 0.7kPa. Target VPD for the week 3-4 veg cycle was 1.0kPa. Target VPD for the week 5+ flower cycle is 1.3-1.4kPa. I am using KIS Organics Water Only Soil with Biochar. This is a living organic compost soil that theoretically should be enough nutrients for the plant through the whole grow. The Nutrient Pack will be used on week 4 (was going to be weeks 4 & 6, but don’t need to now with the shorter veg cycle), Recharge will only be used if growth slows down too much, and Mammoth P will be used one week before and during flowering (was going to be 2 weeks before, but couldn’t because of the shorter veg cycle). The Autopot is a bottom watering unit that uses a float system to turn the water flow on and off, and I won’t need to manually water the plant, but you do need to top-water for the first 7-10 days until the roots get low enough to reach the Autopot tub. Also the supplements mentioned above need to be top-watered on because you cannot run organic supplements through the Autopot lines. Important to note though: do not top-water your Autopots when using synthetic nutrients. Every light cycle stage is/will be programmed with a sunrise and sunset mode where the light intensity starts low and increases, peaks, and then gradually dims before shut off. During week 1 and 2 I ran with a lower intensity and bluer color, and the actual watt average during the light cycle was only at 238W. For week 3 and 4 I changed my light to autorun mode, which is a stronger intensity but still has more blue during the light cycle, and the average light wattage in this cycle is 451W. Autorun mode is the Kind LED K5 XL1000’s default factory setting for a standard sunrise to sunset veg cycle. When I changed to the flower cycle at week 5 I programmed for full spectrum and intensity, but still with a sunrise and sunset ramp up and down. The actual average wattage during the flower cycle is 525W. I really like the Pulse One monitor. It really helps me to keep everything dialed in at all times. The graphing feature is a really great addition because I can now see how bad the environment of the tent would have been without some fine tuning. I fimmed about a week before flipping the lights, but it seemed to be recovering nicely. I’m still on the fence about fimming at this time though, since I think the plant would have turned out about the same anyway.
