Thanks! I gave them a litre with some biobizz just before lights out and misted it again. Is it ok to water the plant (soil) with the light on? I have been waiting til 5 mins before the light goes out on the timer. Today I replaced my 250HPS with a 400HPS bulb and it gives off a good bit of heat.

How large are your containers? Does 1 litre of H2O allow for some runoff out the bottom of the container? I use 5 gallon containers and use approx 2L/watering and water every third day. Tiny amount of runoff. The day before I water the soil is usually dry and shrinking from the side of the container just a bit, but the plants never exhibit signs of thirst like in your picture.
I think my pot is 20litre or about 5 gallon too. There is a good bit of run off from the 1 litre of water. It's sitting in a plate which doesnt overrun. With 2 litres it might. I hope the solution here isnt to repot it as its been under a good bit of stress from the bending and it's kind of tied in there pretty good

Cheers!
