Thank you to all who have taken time to reply. I need to get better at editing the diary! The pot is around 6litres and the HPS light is 300mm from the top of the plant. Light schedule is 19/5.
The main problem seems to be the type of pot I used and the lack of appreciating the importance of PH. The pot had recessed drain holes which effectively trapped all the silty runoff inside the lower 2" of the pot along with all the nutrients I've given the plant (mirical Grow for veg and tomato food for flowering). Any run off that made it out of the pot sat around in a small dish below the pot.
To remedy I installed a large plastic tray covering whole of tent base and drilled holes at the base of the plant pot. A couple of flushes have now been performed and now the PH is better (7). I've given her a very weak feed of tomato food, but will probably stick to water from now on. Any tips on how frequently I should flush would be appreciated. Thanks.
