Watermelon Zkittles - Tremojem Farms

Thank you to all offering help and encouragement. Watered with 1 gallon each including supplements for Cal/Mag and Manganese. Other fertilizers are covered in diary. Looks good and healthy in the tent this week. Not knowing what I am doing is always fun, but with some of the information I have found on the internet, it appears that I should put these babies into flowering stage next Monday. Any thoughts? Both strains seeds came from product I purchased and they fell thru the grinder unharmed. Having said that the Purple Punch, in the rear of tent, and the Watermelon Zkittles, front of tent, are both from found seeds. That alone leads me to the conclusion that 3 to 4 weeks of vegetation state are sufficient, and now it's time to flip the switch to flowering stage. Photo period or Auto...don't know and its something to consider, as I take this next step. Internet says Auto does not depend on light schedule...and photo period does. So this will be interesting. Next Monday I will reduce light time by one hour a night to create a transition period to full 12/12 light schedule. I will start a full feeding schedule as well. The Fox Farms Ocean Forest has now lost its included fertilizer, which fed them for about 5 weeks, so then I started lite feeding. Friday April 29, 2022: I removed the last bit of fan leaves and will not prune again until deep into flowering stage, if applicable. Just readying up for transition week, then full flip to 12/12 lighting schedule. Any advice is appreciated. Hope for the best.
