Blackberry (Auto) - Fast Budz

The plants are growing well again and they were definitely nutrient burnt as the lower leaves (first leaves) developed the browning tips characteristics of this that spread through that leaf. The tallest plant is growing well but the 2nd one is still growing slowly. I have notices the signs of them expressing their sex and can see hairs. I will upload photos later showing their progress. I am going to raise the feedings very slowly as I don't want them to stall in growth anymore to still get a decent yield.
