Well things haven’t particularly gone to plan (do they ever).
Things post transplant were looking up and then the plant basically stopped growing. After a couple weeks of almost no growth, despite not being able to find any pests I came to the conclusion pests were introduced.
I searched and searched and searched with no luck, however there was very minor evidence on the leaves and the leaves were starting to show sign of deformation.
I decided since I had done nothing else to disturb the plant - only had transplanted (which it had recovered from) and had only fed with water to hit it with a pest treatment. (Capt jacks dead bug).
Within 24 hours the plant had completely come back to life and was growing again. After two days I gave the plant a strip down to get some lights to the nodes and get rid of the crowding.
