    I'd say that you were over watering if anything. I used to grow with soil in a 9.5L pot & when I watered, 2L would not give me any runoff at all

    Thanks M_C. This is the weird thing. When I water this auto at the minute water just seems to go through it, whereas it didn't at first. I can't seem to understand it. It is dry down to the second knuckle, feels really light and is even dry at the drainage holes. I'm really confused. To be honest it isn't full right to the top with soil so might only be 10l or less of soil in there.

    Just had a read through on your diary

    Drop the Bio Grow now mate, you don't need the extra nitrogen that it provides now. Your plant has been fairly 'hot' all the way through & looks like it is starting to show it in the form of Nitrogen toxicity...

    The light leafs at the bottom of the plant look like a combination of lack of light & a nitrogen build up... at this stage you can remove them as they ain't doing much apart from looking scrappy

    Unrelated, but of interest, you could also remove some of the bigger fan leafs to promote light penetration to the lower buds

    You're a star matey. I'll drop the Bio Grow. Should I up the level of Bio Bloom at this point bud as only been giving 1ml/l and how often do you think I should feed? Water - Water - Feed?

    I've been thinking about those fan leaves, been trying to tuck them but if you reckon I'm good to take them off I'll be happy to do that if I get more light on them buds. I was worried about it stunting with it being an auto but I will most definitely bow to your superior knowledge M_C.

    I wouldn't up the Bio Bloom at this point... give it a feed, water & then increase to 2ml/L... and watch from there to see if it needs any further adjustments. Really you should feed, feed, feed, but you may be happier to feed, feed, water?

    Your plant is to the point where the large fan leaves look pretty, but are in the way of the result that you want, whip them off - Not all of them, leave any that aren't shading the budding sites (such as towards the bottom ) Aim for around a 40/50% max clear out
