Hologramanswered grow question 2 months ago i would not do it. Using bloom nutes in veg.can give her deformed leaves and other stress(sometimes they even herm!)
But I do not see any problems with her ..Puprle stems can be bc of cold (or bit chilly)
i have had many plants with purplestems.. and they were all healthy!
So dont worry she looks very healthy to me(haf!)
goodluck
