You appear to be recognizing what we are all telling you.
Twice a day watering:
- If your medium is not a moisture holding medium, like rockwool. Water runs through pretty quick so need for watering increases. Hydro growers water more often. But that is also why hyrdo farming produces bigger plants faster.
- Outdoor grower and it is summertime. I grow outdoors in the summer but our temps here in the desert reach 115+ easily in August. We start hitting 100+ by may/jun. In October, I was still 100+. I would water multiple times a day to COOL them off.
You are growing in soil. It will hold water better. If you start in Solo cups, start lifting your cups to get used to the weight. That is how you will know it is time to water.
Transplanting - I grow auto in the winter. Inside an outdoor tent and in my garden too. My temps are still in the upper 80’s. I move my plants in and out of the tent to get PURE SUNSHINE! I start in Peat pods. This way I do not have to transplant, just plant the entire pod in a 3gal cloth. I have transplanted from 1 gal cloth to 3 or 5 gal cloth bags,easily and successfully. If I have one of those plants that outdoes the others, it goes into a larger pot, like the 5 gal. I assume you are indoor tent. No need to fill a 5gal bucket from the getgo. If it is pheno, then it is ok to go to 5 gal after the starter pot.
Here is my GSC auto in a 3gal cloth. Her sister,started same day, was the runt. She got moved into the gray 1 gal cloth
Last pic is the older big sister just 4 days ago before I started really training he. These are auto’s and I fimmed baby sister as a baby and topped big sister as a baby
I have a little DE as I saw a gnat and wanted to nip it in the bud
