Upward leaf curl

[grow jo]

Hello, uh i have a plant that has just alittle bit of upward leaf curl i only fert one time when i trans planted but its the only one doing it no other sighns of anything it looks really healthy nice lushis growth so what do you think overwattering?

[SukonmiSkunk]

its not over watering, it would be a downward curl.... when you say an upward curl, do you mean each finger is curling around on its self, (like how you curl your tounge?) or just at the end of each tip, slightliy curling up?

Usually when the plants leaves curl upwards it means an overdose of something, or a lock up of nutrients, since youve just repotted I would be leaning toward the over fert.... are the tips of the leaves browning or dead?

 

Usually a good flush is in order, I would also spray a little SodaWater, the co2 will help the plant take in the extra nutes better and recover faster.... maybe a weak strength foliar spray after the flush too...

Are all the leaves on the plant affected or is it just the ones at the top? If the curl is along the edges (canoe style) it is usually heat related.

I'm having that problem too. I have two strains growing. On one strain, the leaves are curling up slightly canoe style. Yet the room is between 20deg and 25 deg. And the 1000watt light is no where near the plant. The other strain seems to be doing fine

can be an early sign of nute burn.

I've also experienced this and put it down to a mutant plant, I had six grapefruit and one had canoe curl for it's entire life almost while the rest were healthy as.

Hmm, the tips are dark green like the rest of the leaves. Fuck knows. Edited September 11, 2006 by BentBuddha

i always found that i had the canoe effect where it was too hot in the canopy. generlaly over 30 degrees as it only effects the leaves that seem to be saturated in the heat of the rays! bentbudda is that room temp the canopy temp or the room in general? the room can be 25 but under the lights at the tips of the plants can be closer to 30+.

I have one of those dig therm that have the bit hanging out that is suppose to go outside. I put that bit on my canopy so it's accurate. Only one strain is doing it, the other is fine. And the other one has the lights closer to it btw.
