DP's DP (Dutch passions Durban Poison)

This week I transferred 1 lady from each tub to their individual buckets. Started training on day 17, topped all the ladies and also cleaned up everything below. Topped to 3rd node. At the same time, which in hindsight was rather daft of me considering I had just removed quite a bit of growth, I upped the nutes. Growth still continued well, but I did get some nutrient burn on the fan leaves from the 3rd node. On day 19, started to tie the shoots down to help with the manifold as it progresses. I definitely need to do a res change soon, starting to see a few issues, some spots and also slowed growth on some of the ladies. Problem is I can only get around to it this weekend. I have been topping up with fresh water and adjusting ph, but it still climbed to 6.2. With the next fill I will make sure the solution starts right at 5.8.
