First Ever Grow! Error 404 Autoflowers!

Picked up a new line of nutrients for the plants. Innovating Plant Products. High Output Grow 3 step feed line. Micro-Grow-Bloom liquid solution. I fed the recommended amount for heavy growth. 3 litres of water each plant received 1.5l. I purchased a humidifier, a heat buddy heater, and also a digital thermostat. I put the humidifier at 70% and then changed it to 65% after 3 days. As for the heater I set that to 24-26. I also purchased a tds meter, ph meter, a liquid ph test kit and also a 3 way meter for soil. I checked the soil and it’s roughly 7.8. I then checked my ph of my water with just the liquid solution and I got about 7.5-8. Next watering will be next week as these plants seem to drink it slowly right now. We potentially will have some ph problems with the plants if I don’t get on top of it. So I will be getting some ph up and ph down ASAP it has just been a very busy week and haven’t been able to do it. By the end of the week there was some decent growth. I did a lot of research on these seeds and there’s a potential that they are not autoflowers. So I decided I would top them and just hope for the best. There’s no signs of flowering yet so I figured I may as well. Again First ever grow, I took the info to just do the top as I’m 90% certain they are photoperiod at this point. I took the picture of the nutrients today and I am a week behind. I will be updating next week the same day I am updating this week. Super busy at work but I am trying to document the progress as best as possible.
