Nutrient deficit Flower Week3

Increasing the dose of Bio-Grow can help address this.

Hey GodZilla_Owner, In Flower Week 3, nutrient deficiencies can often arise from imbalanced feeding. Since you're following the Biobizz scheme, make sure your pH is in the optimal range (6.0-6.5) for nutrient uptake. We've also been using Biobizz fertilizers and had similar issues. If your plant has a pale color and is yellowing from the bottom up, it's almost certainly a nitrogen deficiency. Look for these symptoms: Nitrogen Deficiency: Pale color, yellowing from the bottom up. Phosphorus Deficiency: Dark, purplish leaves, slow growth. Potassium Deficiency: Yellowing edges, brown spots. Magnesium Deficiency: Yellowing between leaf veins, starting from the bottom leaves. Ensure proper pH levels, and consider supplementing with a nitrogen-rich fertilizer to address the issue. Good luck with your grow!

SAD #4 photo looks strange, keep an eye for same spot. if you entered blooming, add bio bloom to feeding i never used root juice past second week, strange that its still in your ratio algamic is for coco growers only, in soil no need. ph could be between 6.2-6.5, now 6.8 a bit too high make daylight or when lights are off photo, use flash in second way, very hard to understand what you see with that photo/plant ..
