Just a thing on the Cal/Mg issue, on my last grow the BAM and the TD, I went from start to finish without noticing any signs of Cal/Mg def, I did keep the EC's fairly high though, when I saw some spots on the BAM I actually lowered the EC and the spots went away. Nothing in the way of scientific proof, but it's something to think about and I be watching it on the next grow!!! Great looking AutoX si you been slapped!!!
