I WILL TRY AGAIN l have learned a lot.
Have you thought about what you'll do next?
It would be interesting to see a grow in Kellogg "Raised Bed" soil. I love keeping things simple that way, using stuff anyone can get from the local hardware store.[1] Based upon your photo, I would add 30-50% perlite. (Kellogg has a video on the product page which shows the texture. The texture looks good. Better than the Patio Plus I use to turn soilless into a light soil. But, I like fast-drying soil. I'm pretty sure it would benefit from at least 25% perlite. I would probably go higher.).
I think one of the simplest ways to grow is "soilless" using Pro-Mix HP (contains 35% perlite) with 25% more perlite added. Use
GH Flora Series 3-part and the "useless" schedule.[2] Soilless is between hydro and soil. (No hydro setup, and no biologically-active soil -- it's more sterile like hydro, just you feeding the roots like hydro.). The only thing not simple about that is: you need a ph pen to ph the nutrients each feeding (which means you need calibration fluids, probe cleaning fluid, storage fluid. It adds up. You also need ph-up.). In soil (with it's ph buffers), you shouldn't need that stuff. (After dialing in my nutrient strength, I haven't used my ph pen in 5 years. If you start in soil, you might not be able to get away with that. But, soils shouldn't need that much ph attention. I think when they do, it's due to overfeeding.).
If you want to use a light, airy soil with a nutrient schedule already dialed in: I documented my
soil (<<link) and
nutrients. (<<link). That definitely works. (I've been using it 6 years and afraid to change anything because it just works the way it is.). The bottles I mix aren't necessary. You can just use Grow More - Sea Grow all the way through. If you wanted to substitute your "Raised Bed" for "Patio Plus," I'm sure that should work. It's just 22% of the entire soil mix. As I said, I think the resulting texture would be better. I've never been thrilled with Patio Plus's woody texture. But, it has worked very, very well for me (mixed with Pro-Mix HP and more perlite).
[1] I'm
growing two tests in Kellogg Cactus potting mix with MiracleGro fertilizer (<<link) right now. Had a rough start with too little light day 1, too strong light days 2-5, and the soil has no nutrients. It was hungry the first 10 days, especially for nitrogen. I had a gut feeling that was the problem. But, overfeeding/burning seedlings is a common new-grower mistake. So, my mind kept telling me to wait before feeding too much.
[2] Google for "GH 3 part - Useless' formula." It's on the growkind forum.
I worked out the NPK ratios and PPM strengths (<<link) for each week's feedings. If I grew that way again, I would reduce the strength 10%. Maybe 20%.
