I am currently at day 35 of 12/12, they vegged for 5 days, just until roots came out the bottom of the 4" rockwool cubes. they are Bubba kush, Querkle, and two seeds of unknown parents (not bag seeds, they were given to me by a guy I met at a grow class, but I forgot what they were) anyhow about a week ago the leaves started to curl on me, and growth has stopped on the bk, I mean they look awesome, covered in trichs but all the hairs are turrning brown, and not too much new white hairs, and Im only at 35 days.
They are in hydro Ebb and flow, they are getting flooded 1 time a day, with 1200PPM nutes (GH floro 3 part) with tap water. kept at 5.8 I thought it was too much nutes, I was at about 1500ppm, so I flushed them yesterday(with PHed water), and flooded them with 1200ppm nutes today. If it is a PPM issue, how long after flush should I see improvement? Or what else could this be??? Any input is greatly appritiated.
Here are pics:
Here is the BK with the leaves curling under

And Here is the Querkle, which is curling under and some pointing up

and one other thing, I have no idea how this happened, but a sprout has appeared next to one of my plants, they are in hydro and in rapid rooters sitting inside rockwool, I dont get where a seed could have came from. I was thinking it was a root that started a new plant or something, but I dont get why the leaves would be round, like a seed sprout would be. Any ideas?

Would like to add, this problem is mainly the middles of the plants, like all the leaves that were not getting as much light.

leaf curling down is usually high nitrogen... also looks like some leaf tips are burnt meaning you mix is to strong....

you should be fine if you lower your ppm's or cut out a feeding prob just lower your ppm's.... flush for a day to be safe doesnt look to out of control but problems have started...

Right now I have been giving them 3:2 ratio Bloom to Micro, should I cut back on the Micro? I know that has some N in it.

thanks a lot for the reply btw
and also I just realized that I might have posted this in the wrong section. I think i should have posted in the "cannabis infirmary" Mods, feel free to move this if it should not be here.

I did feed them grow during the 5 days they vegged. Could this have cause too much n to be stored up, and now causing me problems? and if so, would 1 flush, then back to lower strength nutes fix this?

I thought 2:3 was the right Micro-Bloom ratio, well acording to the GH feeding chart, this is wrong. durring bloom they should get 5-10-15 (or 2:3 micro to bloom) and durring aggressive bloom they should be getting 0-10-20 (or 1:2 micro to bloom) 2:3 and 1:2 are pretty different, I have been running this ratio since start of 12/12. And this really bites, as I just changed my nute tanks yesterday :mad: anyone think this could be my problem?

ive never used gh... but you might just have a sesitive plant that dont need alot of nutes... Remember what the bottle says is a guideline every plant is different....

Ok, I am gonna go change the nutes. I will use the ratio that they recommend for "aggressive bloom" but not at the strength they recommend. I hope this will fix the problem. I will keep this thread updated. Thanks again.

still same issues. Plants never really started growing again. Have my second table up and running, got about 80 on it, they are 3 weeks in, and they all have the claw as well x_X
They are only at 1000 PPM, and I'm even using a different line of nutes with them (cutting edge solutions 3 part stuff) I really don't get it. Its so frustrating. could it be a rot rot problem? The roots under my grow mat are a little brown, but I hear that GH nutes do this.

..only at1000 PPM, .

Top pick almost looks like leaves could be deforming from being to close the your light, but you said they recieving less light...so

1000 PPM is still high IMO especially if you over-fertilized. I mean 200 parts per million less of a solution wont do the trick if thats your prob.

I would immediately cut the solution down to at the most 600PPM for a week. Cut the wrinkled leaves back to see if your doing whats needed..the sun leaves wont "undamage".

Flush with plain water for a day before giving 600ppm. Lower you PH to 5.2 - Some easy steps to rule out overnuting...
Most often with nutes...less IS more..

p.s. thats not a cannabis sprout. arrant seed perhaps in your medium, airbourne or from manufacturer more likely the latter..

when I said 1000ppm I was reffering to my new table I have set up. They are 3 weeks old, getting 1000 PPM the whole time, and they are having the same leaf curl. and as for the sprout, I think it is a weed, like the outside grow on your lawn type. not the one you smoke lol. It is getting hella bigger, I will take a pic and post it tomorrow. Its kinda funny, if it gets too big I will pull it, but for now it stays.

I was reading this article:
http://www.simplyhydro.com/nutrient_problems.htm
about algea. I have been struggling with algae throughout this crop. And in this article it says decomposing algae can lead to other problems
"Decomposing algae may also release toxins as it breaks down and provides a food source for plant pathogenic fungi which may then multiply to high levels in the system."
could this be the issue? It also says decomposing algae has a earthy smell, and when I lift up my mat and look at my roots, all brown and shit, it does have a very earthy smell, like dirt out of the garden or compost pile. any thoughts anyone?

Seems like you should pull that now dude. why would you want something competing with your root system like that?

Yeah, you are probably right. It just tripped me out having that thing sprout out of no where... and the irony of a weed growing amongst my weed. anyhow, I will pull it out when the lights come back on.

yes, try and focus on one perceived problem at a time. OR you can just chop the bud and let your "weed" grow out ; )
yeah you are absolutely right, I'm gonna go right now and cut all the buds down, that way my "weed" can get all the light. great idea genius, have any more?

You use sarcasm... yet you failed to get mine. What a fucking jerkoff you are with your pathetic questions. And you dont even appreciate the good advice.
Go fuck yourself, after that, get a basic grow guide.
