My very first grow. RIP: PH issue. ✞ ✞

Starting this diary just to document my very first grow and learn from my mistakes :) (and hopefully get some help if everything goes south) Anyway, let's start! First, why Autoflowering strains? After a lot of reading, I decided i wanted a simplified first grow. I'm a bit afraid of messing with light times and stuff like that yet and I wanted first and fast run so I could get a grasp of how these plants behave. On the other hand I've also read that autos may be a little bit more trickier to grow... So yeah... I'll just take a leap of faith on this one. My setup: I got a starter kit on my local grow shop. I built the kit (which didnt include the humidifier nor the hygrometer/thermometer), and gave it a dry run. Luckily I did add the hygrometer/thermo since I discovered the 400w HPS light raised the temperatures to 35 Celsius inside the tent and it also dropped the natural humidity of my house from 63% to 40%. I bought a Xiao Mi Humidifier (not sure if it was the best decision but it was the only thing I had available). I also got an intake fan and an extractor (110mm each). Tested again (turned on everything for 2 hours) and got the humidity back to 65% which I believe is ok for germination and the seedling stage, and the temp raised to 27 Celsius (I'm a bit afraid it may go up after an entire day). I also have an autopot easy2grow prepared for irrigation. I may be out of the country for a week, so I've got one of these systems to keep my plants irrigated. Germination and grow: Im following Tourette Grower in YouTube who specializes in Autos. He did a grow using autopot and Autos too. He started by saturating the soil with water, and 24 hours later planted the seeds. That first irrigation of the soil was enough for almost 2 weeks of growth. At that point he turned the autopot system on. I'll be following almost the same process. I filled two 14 liters pots, one with custom substrate from my local growshop and another one with Monkey Pro Light Mix and saturated them with 3 liters of water and 1.5ml of Plagron Power Roots (0.5ml per liter). I'll leave those pots overnight in the tent and the same time I put 2 Blueberry XXL Seeds between soaked paper towels inside a tupper (in a drak place). I'll leave them there overnight and then move them directly to the soil in the morning. Wish me luck!!! (and if somebody reads this feel free to leave any tips or feedback; if you think Im butchering these seeds please let me know!!! 😬) Day 1: everything quiet Day 2: everything quiet Day 3: one sprout appeared with white cotyledons; slowly opened and turned bright green; the other blueberry hasn't sprout yet Day 4: the seedling stretched a bit. I lowered the HPS light to prevent further stretching but this caused an increase in temps from 24 celsius to 25.5 (kinda dangerous) Day 5: (a brief power outage left my humidifier went offline, humidity dropped to 57% almost the entire night); the seedling was a bit down probably due to low humidity and the soil got a bit dry. I sprayed the seedling, turned on again the humidifier and irrigated the soil with 250 cc of plain water (not sure if thats too much) Improvised a dome to keep humidity for the seedling and stop relying on the humidifier so much in this critical stage. The other seed havent germinated yet; I got anxious, dug out the seed, found out it was barely beginning to open so I replanted it with more water and less depth (maybe that will help if i didnt kill it with all the handling). Im stressed and anxious :/ Day 6: nothing new Day 7: i finally managed to get an acceptable disposition fo the items in the tent (humidifier, plants, hygrometer, etc). The tent in the pictures, the light, etc, was a starter kit i bought at a local growshop. There is not too much information on the internet on how to use/prepare these kits, but nobody seems to talk about how DIFFICULT is to nail the disposition of each piece of hardware in order to get the right temps and humidity. I believe I may have stressed the seedling a bit these last few days. I now have a constant reading of 60% humidity and 22 Celsius at "night" and 65% humidity and 24 Celsius during the day. I also managed to keep my fan constantly on to keep the air flowing. Until today, turning my fan on caused the humidity to drop below 55% down to 45% sometimes and my temps to climb up to 28 Celsius. Also the 400hps light heats a LOT which causes that i cant lower the light as much as id like to. I believe this was a poorly planned kit... Im a bit angry and disappointed at this growshop. I had to spends extra money to get smart power sockets, smart hygrometers, just to be able to keep a constant monitoring and control of something that was supposed to just work OOB. DO NOT BUY KITS... get a a growing sensei and ask for guidance...
