Question for experienced Biobizz users

Hi all,

I have recently switched to Biobizz and I am suffering some P deficiencies. The plants were in coco coir and are now in Biobizz Light Mix and about 6 weeks along in veg. I have been following the Biobizz feed schedule for veg with 2 ml of Grow per L as well as using GH CalMag+. Plants began showing P deficiencies almost right away. I had transplanted them from coco coir, and I assumed they were suffering some shock, but it has now been 4 weeks and the P deficiency has progressed. I'm trying to get a hold on it. I've checked pH in and out, and they check good.

Considering the Biobizz Grow is a 3-0-8, I assume that's where my P deficiency is coming from, but the rep insisted I wouldn't get a P deficiency, so I stuck it out, but now I'm considering adding the Bloom to veg. I am not looking to add any animal products or chemical ferts to this crop.

I was just wondering if any one out there with experience using Biobizz products and light soils has encountered this and how to fix it, and, also, what feed schedule do you follow/would you recommend in a light soil?
