  1. I often think I’ve mislabeled my purple and green varieties. lol good to know for my Australian spring in 6 months. Thanks Luke

  2. I know Luke really wanted to say this, LOL, but I think he forgot, is to have your soil tested as well if possible. That way you know right away what deficiencies you might have in your garden beds.
    Hope this helps somebody

  3. Hi from Melbourne Australia, I had that problem when my tomato seedling were growing which it did rectify itself, but I didn't know it was a lack of phosphorus ill make sure to add some in the potting mix next year thanks.

  4. I always thought this was happening because my tomato plants got a little chilly. Good to know the truth

  5. Hey Luke, I'm curious about something. I've always heard that water soluble fertilizers are bio-available immediately, but that granular slow-release fertilizer is meant to "feed the soil" and is slowly broken down by the soil microbes over time make it bio-available. How does granular slow-release fertilizer work in a sterile potting mix?

  6. I had noticed this on my tomato seedlings in the past, no clue why. But now i'm using Trifecta+, very happy with it! Thank you, super interesting. Yes please, more trouble shooting videos!

  7. Thank you. Very helpful. I was wondering what was causing this issue. You explained it very well and also gave a solution for it if it's needed. This was great. Thank you for sharing your knowledge. 🍅🫑

  8. Interesting timing on this video. This is the first years I have ever got a lot of purple leaves. A few small cases in the past. But I had like two full trays of purple leaves. It was weird. Never seen that before.

  9. To build on this for blueberries, having just saved one of my yearling bushes, if you're seeing slow growth out of dormancy and red leaves, it's a good chance your soil isn't acidic enough. A cheap pH tester is ABSOLUTELY your best friend to be sure, but amend the soil as soon as you can. You can add slowly (due to plant and pot size, I added half the recommendation of my fertilizer) to ensure you don't overshoot the pH. Just let it sit a couple weeks between feedings before you test the soil, about 2 inches deep, again to check pH.
