Okay so this week I really learned patience and to stop being so intense. I moved the Wedding Cake from the pot to a red cup (with drainage holes) at the beginning of the week, it was not fairing well in that pot it was drowning.
I put the Grapefruit seedling in the soil with a sandwich baggie, misted with that nutrient mix water; it popped about two days later.
Towards the end of the week I mixed a new batch of soil! I have a 3 ½ so this was done in a small living room, using a tarp avoids a mess. This is Fox Farm Ocean Forrest soil. You honestly don't need to add to this but I wanted to personally. I have soil from back home (apparently it's illegal to transport soil?? idk) and vegetable compost from my parents garden (they have a DIY compost mega bin) which I worked in, along with the perlite to make sure the soil was nice and airy (especially after the overwatering incident).
I also transplanted the Wedding Cake and Grapefruit, with the same mycorrhizae on the root ball. This helps the roots get the nutrients available in the soil and provides your plant with a symbiotic relationship; nutrients for sugars!
I gave the White Widow and LA Ultra ONE MORE SHOT, this time soaking them in a hydrogen peroxide dilution (this is how we do it home, because it's usually an outdoor grow with manure compost being used, to make sure you're starting clean) for 24 hrs and then planting them in these little tiny cardboard pots I got at the dollar store. Baggied and misted with the same nutrient water, after 2-3 days the LA Ultra popped, but the White Widow did not.
It's rude, I really wanted the White Widow out of all of them! Oh well, you make plans and the universe laughs right? I've given up on this strain for now and I'm working with three plants. Essentially I'm only going to flower when the LA Ultra is nice and bushy. The seeds I have are guaranteed females and not auto or fast seeds, so I can decide how long to vegetate. In my experience, the longer you vegetate and create a bushy strong plant, the better in the end.
