i always use bio-vega at least 2 weeks into bloom unless the strain dictates otherwise,then straight onto a small of bio flores,my guess would be that the ph is out for starters,,good luck,,,s2with biovega gotta feed into week 3 of flower.. so u don't get the early yellowing.. basicly u use vega and flower.. together at week 3.. so 2 weeks with vega in flower..
