New Grower Need Help

If you want to continue with her i would transplant to a richer soil and let her grow naturally just water and some root stimulator

I there ! After 5 weeks it's fair to say that it will be hard to make her healthy again. I think it will not worth it , a 're start could be a better idea bro 😓🌱

Hi @Huicho! You may consider using a physical barrier, I've managed to build some great protections with plastic bottles (for seedlings), or using tarpaulin around stakes for bigger plants. If you want to prevent slugs & snails from eating your baby, a beer-trap would be a good way to attract them away. You need to mix some flour in beer in a shallow container (split a yoghourt pot in its height) and push it into the ground, so the invaders can fall into. For thrips & spidermites, neem-oil is one of the best organic repellent, mix 12~15 drops of pure neem-oil in a liter of water and spray this solution onto your baby at night or in the early morning. Finally, you can plant some flowers & aromatics in your garden to attract everything away from your Blueberry. Prevention is the key. By multiplying your approaches, you'll win this fight and be rewarded soon ;-) Hope this will help, keep us up-to-date and happy growing! 👊

The yellowing is probably due to lack of Nitrogen and/or roots-related issue (root-bound). You should transplant this baby into a bigger container with fresh medium and give it a few veg nutrients.
