Dirty's First Grow

3/2 I gave my plant its first feeding. Gave it about half a gallon of water with a PPM of 500. I also thought about topping my plant but am not really sure where. I am not sure what one is the top spot as this is my first time every growing. I also finally received my ACInfinity CLOUDFORGE T3. This has allowed me to get my Humidity levels more under control. I was okay before because of the dome but for the last week or so I have not had a domain and my humidity has not really be regulated. 3/2 A few hours later I said fuck it and just cut the plant where I thought the top was. I cut off a few lower fan leaves. Not sure If its too early to do it or not. 3/3 Finally got my ventilation setup. I am not longer venting into the room my tent is in. I now have the exhaust being vented outside. This has allowed for better temps in tent. I am not longer being baked alive. I have also noticed a lot more stability with my temps/humidity now. Temps are sitting at 78-80ish and my humidity is sitting around 60 percent. 3/5 I started LST as my gardening ties arrived this day as well. 3/6 Today I gave just shy of 1 gallon of RO/DI water with a pinch of Epsom salt. I was waiting off as I forgot to added to my first feed on the the second. After the watering I also saw my rapid rooter exposed as the soil seemed low. I think I didn't fill the pot enough. I also added some extra soil to top up the pot and make sure the rapid rooter was buried. I also collected my run off and checked its PH and PPM. PH was 6.2 and PPM was 863. Plant also seems unhappy this morning.
