First Indoor Grow, Up to All Criticism

First Indoor Grow. Would like to start with a huge thank you to all the growers who helped me get my temperature down, first week has been somewhat smooth so far, I have only sprinkled Dynomyco into the hole before putting the seeds in soil. I have Gaia 444 and Power Bloom but I believe I’m supposed to wait until the transplant into 3gals to add them. Please correct me if I’m wrong, this grow is 100% acceptive of criticism and advice. Only huge problem as of the moment is my PPM is quite high at 1,136 last I checked. Apologies for the late start on the Grow Diary as it’s my first time using the software and first indoor grow. The community has been super supportive so far which is much appreciated. I’ve been watering in layers until a little water starts coming out of the bottom of the solo cup. Help on when is a good relative time to switch to the 3gals is much appreciated as well. Thanks everyone.
