Canna PK 13/14 Will my problem be solved if I buy this product?

Langbeinite 0-10-10 )Hello, I can't find the product you're talking about in Turkey, will it work if I increase my own fertilizers? I'm also a beginner, I use a translator, I beg you, explain it to me in a very simple way.

Looking at your diary, she's not getting enough normal NPK nutes here... she's need a LOT more P and K (what you're seeing is a phosphorus deficiency)... but don't increase the nitrogen as she's not needing as much of that as she does during veg. The Canna Boost and the Bio Heaven help the plant to efficiently absorb nutes - but you have to give the plants nutes to begin with! In a soil grow, if you're not going to go for a good PK booster, one way to increase the phosphorus is to top dress 1 tablespoon of Langbeinite 0-10-10 once a month... Langbeinite is not easily soluable unless you maybe put it in a grinder and reduce it to powder form... so top-dressing is a way to provide the plant with phosphorus everytime you hit the soil with anything liquid... Good luck!
