Hey there, bro! 👋 Your plant has entered the pre-flowering stage, and soon the first flowers will appear! It's best to reduce the grow supplement and increase the bloom supplement in a ratio of 1:3 (grow:bloom), and also, if you're growing in soil, set the pH level to around 6.2. In soil, it's better to stick to pH values of 6.0-6.5, and your 5.9 is a bit too acidic for soil! 👌😇👍 Good luck, bro! 👋
