Raspberry Cough 2021

Plants started to show signs of phosphorus deficiency mid last week, and it accelerated very quickly! (You can see in the 3rd picture) I've been adding flower fuel which is like (1-32-34) ; Did a flush as I hadn't done before, thinking ph was getting low in the soil (Been watering at 6.3, but runoff around 5.9.) perhaps locking out as read phosphorus uptake needs a little higher ph than the overall plant. Flushed, and then watered with the flower fuel. Looks like it worked as it hasn't gotten any worse and they seem overall OK. Didn't have to trim too many leaves and these plants have plenty to spare anyways.... Thinking another 3 or 4 weeks for these. Starting to fatten up nicely I think, and really happy how they've stayed bushy and same size. Trying to defoliate a bit as we go to get some light to the lower buds.
