Blackberry Auto Indoor Veg Tent Sumer Fast Buds

First week of flower shes doing pretty good but looks like the soil dried out just a little to much resulting in a high ec/ acidic ph that caused a little leave-tip burn. Its not to severe but looks kind if ugly. I forgot that auto-flowers tend to not need as much as photoperiods. Buds are growing fast and showing cool purple color already. Was thinking i may need to top dress based on the other auto i grew but im going to wait for this one because it seems to not be as hungry as the others. Blackberry more or less has its own 4x4 space now.
