    canoeing leaves are usually caused by heat stress,
    p/k is a booster and usually very strong - my bottle says 2ml pk, i never add more than 0.5ml

    probably why they are showing slight signs of overfeeding

    its not canoeing..... they are bending... if anything its closer to Clawing..... which is again going to be directly related to your over feed. You said you backed them off, so I am guessing that you hit them pretty good previously with some nutes, so just back things off for a while and they will straighten back out. Some of the bending leafs coulf just be the way she fnishes.

    I was thinking heat stress but my max is 28 c and minimum is 19C so would it be the fact there is such a big gap between the min and max causing this?because i was thought that up to 10 C difference is ok?

    Also i was giving them 0.5ml per litrel pk anyway and i have dropped it to nothing all of a sudden. After a closer inspection before it looks like a p/k deficiency now as i also dropped my A and B from 0.75ml per litre to 0.5 ml so thats even less again..

    The stems are getting quite bendy aswel so I was thinking overwatering might be a factor, even though they are in coco..

    It might be they way she finishes but i have seen signs of a pk def. Just before lights off and it has spread fairly quickly but is not dramatic just yet.

    If anything they were underfed early on and i have been careful not to overfeed and after looking into it im pretty certain its a deficiency and not overfeeding

    Well you cant over water in coco imo...... Canoeing or heat stress will show itself with the leaves curling inwards, from the sides and the ends. THis is the plant trying to cover itself up to help shade the light. You will also get bleaching. It very well could be a deficency, but you would need to break down your feeding a lot more to figure that one out. What is your lighting situation? If it were me I dont think I would be too worried at this point, things look pretty solid.

    Yeah i know you cant overwater in coco but im putting 2 litres through the mutant and then getting 1.6 litres back as run off...

    Others are around 50 percent run off, if not more..

    Im running a 400w hps. And tbh im not sure theyre getting too much light.

    Its no co incidence that i stopped using pk and all of a sudden its showing signs of a pk def.

    You've mentioned twice about PK deficiency but not mentioned why you think so....

    I did mate, i thought it might be because i dropped the pk so suddenly? and maybe at the wrong time.. also some leaves have started show brown spots/patches along with the tips on some leaves showing the most brown ive ever seen them.

    I know theses pics are under hps but i cant hold the cfl and take a picture with my tablet as ive got limited hands . Haha
