Because I have a tad bit of understanding reality where it concerns botany. High P in containers is a waste and nutes need to be balanced for plants to be healthy. Every day there is a problem post here because a new grower started usin bloom nutes & boosters wrong. Then there is this email from the CEO of DynaGro, you know the guys that developed hydro nutes for NASA ,,,,,,,,,,,,,,,,,,
You are correct. We market a high P (Liquid Bloom) as some "believe" they need this. As you have noted, our Foliage-Pro does a great job start to finish. However, it is simpler to give the market what they think they need than to try to reeducate it. There is some evidence to believe that low N helps to convince a plant to stop its vegetative growth and move into its reproductive phase (flowering), but environmental factors are probably more important. P is typically 5th or 6th in order of importance of the six macronutrients. There is little scientific justification for higher P formulas, but marketing does come into play for the vast majority of users who lack any real understanding of plant nutritional requirements. Therefore, the market is flooded with a plethora of snake oil products that provide little benefit and can actually do harm. For example, one exhibitor at a hydroponic trade show had a calcium supplement with 2% calcium derived from calcium chloride. Can you guess what continued application of 2% chloride would do to plants?'\
I hope this answers your question and am sorry for Zina's inaccurate response.
