My crowded bonchi grow

Growing Aji picante, Purple pumpkin, Citron and Scotch bonnets (clockwise from left back).

Bonnets failed to germinate, so they are a month younger than the rest (most started in oct). I only recently realised that I've had my lamp too close/strong and have thus stunted some growth…not that it is really that much of an issue as I am still a beginner and more into bonchis than maximising production currently.

Had some nutrient issues (too much nitrogen) earlier too, but everything seems to be going well now. Growing in a slightly modified hydroponic NFT where I've added a bubbler and imrpoved the water flow to the table.
