When to start fertilising with Bio-Bloom?

Congratulations, it’s an exciting time! You saw correctly: these small white filaments which appear at the nodes of the branches are indeed pistils, which confirms that your plant is entering its pre-flowering phase. ​Here is how I would handle the introduction of Bio-Bloom: ​1. The timing for Bio-Bloom No immediate emergency: Even if the first white hairs are there, the plant will now begin its "stretch" (accelerated growth). During this period, it still has a great need for Nitrogen (N), contained mainly in Bio-Grow. ​My recommendation: You can start adding half a dose of Bio-Bloom during the next watering, but don't stop the Bio-Grow right away. The plant needs both to build its flowering structure. ​2. The gradual transition ​Mixture: The ideal with Biobizz is to make a gentle transition. Continue the Bio-Grow at normal dose and introduce the Bio-Bloom at approximately 1ml/L. ​Observation: Watch how the plant reacts. If the green of the leaves remains very deep like on your other growing plants, the dosage is good. ​3. Why wait a bit for the full dose? ​Bio-Bloom is rich in Phosphorus (P) and Potassium (K), essential for making the buds swell. ​Currently, your plant is still “making” stems and leaves. Too much Phosphorus too early can sometimes block the absorption of other nutrients necessary for stretch. ​In summary: Yes, start adding it very lightly (1ml/L) at the next watering to prepare the ground, but keep your growth fertilizer as the main base for another good week .have nice day
