have them in pro-mix,plant is about 18 inches high,budding for 4 weeks under 2 warm and 2 cool 23 and 42 watt compact flouro`s and a 70 watt hps. temp is about 83 degrees,still feeding at 1\4 strenght ferts,
the leaves are green and the color looks good,they are just curling at the top
have also given her epsom salt at 1\4 teaspoon about a week ago,could this be a heat prob???
Heat can cause misshapen high leaves like that but they typically cup UPWARDS.
That looks to me like your plant is root bound.
How tall is it and what is the volume of dirt? You want approximately 4 L soil per foot of plant.
Other things that can cause that are overwatering and not enough ventilation.
Are you growing in kitty litter pans?
I personally think that a container that is DEEPER for its volume is a more efficient use of floor space as you can cluster plants closer together btw.
yes they are kitty litter like bit just a touch smaller,it`s a one gallon pot,the plant is about 18 inches high,well i`ll try transplanting
thanks for the help
and i have 3 fans one on the ground blowing in and it`s a 8 inch fan and 2 4 inch ones at the top to pull air out
Yeah sounds rootbound... or if you are unlucky, a more serious root problem... do you let the soil get pretty dry between waterings? How's the drainage?
Left hooker sorry to hijack ur thread :wtf:
Intresting you say root related problems stinky attic are these symptoms common with root problems? I ask because i have aplant in veg showing these same symptoms but she is hydro could a severe pH problem in early veg cuase root damage in hydro? If so could it be repaired?the postman
Well I am not much of a hydro expert but plants that I have seen that are suffering from rootbound-ness or root rot show those canoe leaves, although if you had real root rot you would see other problems too. Hmmm better ask in hydro for a real answer! What I see though is that shape coming from a situation where roots can't keep up with transpiration... I've also seen it in a confined space that did not have good fresh air exchange... the far corners of my own closet seemed to breed canoe leaves like crazy until I added more fans. That's just an observation!
In lefthooker's case it's going to be harder to remedy because of the unconventional container shape... repotting is going to have to be into something like a tote bin!
Thanks stinkyattic This makes perfect sense i have dismantled my grow room in the last few week taking out the inlet fan for another project so airflow must be the problem and to think about it what i may have been putting down to pH probs can be tracked back to the removal of the fan so thanks .damn learn sommit every day:thumbsup: the postman.
again leftfthooker sorry for interupting
i pretty much let them go completely dry before i water,and that`s about every 2 or 3 days
I think ventilation and root problems are very closely related as they both result in poor uptake of shit the plant needs!
If this was a root related problem what would you recomend to rectify the problem.The hydro shop dude recomended a product called AU 60 have you heard of this product.the thing being stinky attic is that it is only occuring to 2 plants out of 5 so if it were air flow prob sure all plants would be affected and even if it was root surely all plants would show same problems .Um really trying to elliminate theories as i go along .thanks for the help stinky attic
I've never heard of that product.
Why don't you try rearranging your fans? Or rearranging your plants, and see how they react? Air flow can be hard like that; since it's invisible you don't necessarily SEE that there's a 'dead spot' somewhere in your grow room where air just stagnates... in my veg room it used to be in a back corner... in my friend's room it's also in a corner... those little $5 walmart metal fans are good for scattering around the room and eliminating that shit.
Thans again stinky attic i will stick a few fans blowing air around the room see if that does any good im kinda pissed with this hydro grow just thinking of taking as many cuts as i can and going back to soil for flower i hate stress ing plants in veg and funny its the 2 plants in the back right hand corner of the unit with me being in the attic its an open space as the grow rooms half dismantled maybe me and hydro just aint compatable lol. .thanks again for ur input mate.the postman
transplanted and added a fan ,now have 4 fans in there but it`s looking better.
thanks for all the info guys
Any pics???
Keep the fans pointed at the roots. The leaves can handle the heat without probs but the roots can not and should be kept below 70 degrees, 60 if possible. Plus it won't blow the leaves around as much which dehydrates them and causes more odor problems than if not disturbed. Also PH your water. It looks as though they have lost their entire lower canopy and it'll be working it's way up unless you fix it.
the problem you are having is from too much nitrogen cut your nutes 100 ppm and that will solve it. the leaves already curled will never un curl
Actually yes I just discovered a couple plants in my own garden that I knew had been over-N'd and they are doing that. But that's with a high N veg nute!Quote:
