Thanks for the reply kur4o, I looked into it being a phosphorous like you had suggested,and was reading this
http://www.marijuana-seeds.net/Thanks/ThankYou.htm
and some of the symptoms do match ie: curling and dark green and purple leaves, stunted growth, and leave curling. But the pics they show as examples don't really look like mine, like the leaves dieng at the ends for instance.
I have been struggling with slime in my res on both tables, could this lead to root rot, or have anything to d with it?

Also like to add that I am using a ebb and flow set up, and they get flooded once a day to once every other day. They are in 4" rockwool cubes on top of a thin coco mat. I thought I would be watering more frequently, but I can easily go 2 days without flooding. they are barley taking up any water.

In in ebb and flow, your nutrient salts tend to gather at the top of the medium. Mearly cutting back on nutes wont help. Those little fuckers need to get flushed. Its probably N overfert but who cares what it is-flush it out. you can fill your res will plain water run it then change it to half strenth. Then work your way back up to higher ppms. Remember even after you flush the plant still has a substantial amout of stored nutrients. I would top flush. Then hit em back up with half strenth. After you water your rockwool turn the cube so that a corner is pointing to the ground-water will streem down-get it into a small container. If the ppm's and ph are not right start again. Thats the great thing about rockwool sooooo fushable/repairable. Good Luck
Thanks a lot for the input Randy. I actually just chopped this whole table today, but my second table is having the exact same problem. and I did top flush the other table, big time twice, but I did not work my way back up slowly. I did a major top flush and then straight back to full strength
Would also like to add that When looking at the roots under the mat, alot of the roots were really brown and a tiny bit slimy, also there was some mold under mat and in between blocks.

well This next run I am in the proccess of setting up, I think I am going to ditch the coco mat, and use some 6" square pots with loose small rockwool growcubes in the bottom with 4"rockwool cubes sitting on top. I was just going to use the cubes, but I wasn't sure how well it could hold up a nice fat cola at the end of flower. I am hopping the change will fix the leaf curl issues.... any advice anyone?
I think you have a root rot mold problem. It`s caused by anaerobic bacteria pythium. The color of the roots should be white. Solution is very simple. You need H2O2 or hydrogen peroxide, preferably 30% food grade. The free oxygen atom will attach to the bacteria and kill it. If the problem is severe you need to put some every day. How much to put. It depends. Usually if there is a problem with root rot you put every day 20 ml or one big table spoon 30% H2O2 on 10-12 gallons of solution. If roots are in good health and white you put every second or third day to prevent future troubles.
You should keep the roots in perfect health no matter what.
You can also add aquarium air pump and UV-C water filter to your reservoir, to keep your nutrient solution oxydised and sterile as much as possible.
Also good idea before you put your plants, run your system 24 hours with cleaning solution /10 gallon water with 1 litre H2O2 30%/to clean everything up.
Keep it Hydro you won`t regret.
When
leaves curl like that It`s classic P deficiency, even in veg it shows like that.

When leaves don`t get enough light they not only curl down but loose their luster. Yellowing sets in and eventually the leaf contorts and drops off. Flush your plants and leave them be for a day or 2. Give them nothing but plain water for a couple days. Sometimes when flushing,if not flushed enough the problem goes nowhere at all. Severe problems often require more flushing. Though your problem does not look severe above ground it may look severe down below. Keep your ph steady and drop your PPM`s to around 600 as previously stated. Wait a couple days to see how the plants respond. If they need more then give,if not then don`t. To top things off being that you are growing hydro you really have NO room for mistakes. 1 wrong move could mean toast! Be careful,be patient and be watchful..all the rest will fall in place for ya! Good luck to ya and Keep It GreeN!
Makes me laugh that some people hand out advise and they aint in the slightest got a clue what they on about LOL- That is not a P def buddy imo, you should almost see a blue mottle colour to the leaf. My bet would be ya nute are too hot/strong.(leaf curl can be either way up/down with P def)

here are some more pics of the curl. also have a few pics of an unknown strain that I came across.(these got no veg time btw, clone straight into 12/12) I cut one at 8 weeks, one of them is getting chopped tomorrow (9 weeks) and one a week after that to see how she does best. I think shes a keeper. The one I already cut was 1/2 oz and these two look way bigger. Only problem is I can see some seeds in her. Im hoping it was just a little pollen from one of the hermis that got pulled out (at the end of week 1 12/12,caught them early) I hope this isn't in the genetics because this is an otherwise Killer looking strain.
Right dude,
I'm gonna try help-out here, this is called Rams-Horn/horning imo the start of it.
This can be caused by too high 'N' & lock & other element def/lock too-what nutes&adds you using buddy?
i'm gonna do a little more research for you n get back to you asap!!
(Edit)-Yeah sounds like i could be correct i need to know what nutes & additives you use, as the main culprit seems to be high N, the leaves are very dark whick could indicate too high N but i am speculating by the way, this seems very possible looking at your pics.
Do you use kelp or any high N additives? you have made the right choice lowering the ppm of your solution, stick with it for now. i await your response!!!
