    I shall take another photo of the roots later, they look alright. Growth been abit slow but thinks that’s down to me being a newbie idiot, I chopped leaves off a clone when it was was under a few weeks old and could have really done with them.

    I'm definitely no expert and I'm not suggesting that he should go out and buy a large pump but I do think that his current pump is under powered, I would definitely go with 5-7lpm in a bucket but that's my 2 cents!

    Cheers good advice regarding the ph perfect. I was wondering why it kept going a little higher. Have you got a rough guide to how much you feed at each stage? I’m keeping the ec at about 1 using micro grow bloom rhino skin and about to make next res with big bud. Have you got any dwc journals? Cheers

    Especially when those roots fill the bucket and cover the airstones!

    @d.t I think you hit the nail on the head. I was going to bring this up earlier and got distracted. IMPO you have defoliated way too much. There are no leaves to make energy for the plant to grow. Another thing I noticed is the effect of the water level dropping in the reservoir. The area in the red circle has no side roots because they are drying out and dying off in the air. They most likely will never take in nutrients in that section again.

    This is what a healthy root system looks like. Notice the side branching roots start right below the net pot.

    Got some problems here but not sure what. Theres a ‘rusty’ look on some of the older fan leaves. Could be from few possible things I want sorted. Guess it’s a ‘lockout’ or something to do with that rule of minimums?
    Also could be caused from cold temps? I have no reservoir heater or Thermostat in there so no idea how cold it’s getting at night, soon it shall be really getting cold so need to get one ASAP.
    Or from not changing the res often enough. Or something else.. finding it a massive chore changing the reservoir as it’s cramped and seems hugely wasteful using so many nutrients.
    Makes me really appreciate the autopot only using what it needs.
    Starting to flower though and most the leaves a nice dark green just don’t like this rusty nasty look at all.

    You better turn that leaf over and look for bugs.

    Definitely no bugs. It’s some kind of deficiency but not sure what. Seems to get worse towards the end of the week before a fresh nutirent mix. The temps have been going way too low down to 8c so good chance it’s related to that, got a heater on the way for the next grow. This has been like a little lesson in dwc, so many mistakes lots learnt. Not bothered too much as main grow is her mum in soil and she’s doing ok, leaves a little pale but she’s smelling great. Here’s some more photos of the horrible leaves, it’s a rusty look and the leaves feel a bit dry and brittle.

    Never had problems like this in soil. It could be some kind of micro deficiency but I’m changing the nutrients every week now so not sure why unless it’s the temperature. Il get a new pump soon as well, despite the troubles I have had i shall be re doing it as can’t quit it just because of some troubles, got to get something good out of these mistakes.
