Hey guys. 2 of my 3 plants are showing strange leaf curl. The whole leaf is curling downward not just tips. Also the leafs curling seem to be just the budding leafs not the fans.
1 Ph is good.
2 Watering on schedule.
3 Been watering past few days with only water. no nutes.
4 Bottom of pots dont seem to have roots trying to bust out.
5 Plant seems to be sativa.
Plz help guys.
p.s. PIC #1 shows it best
anyone?
Sulfur deficiency?
when ever mine curl like that it is caused by too much nitrogen my jeti always do that before the leave tips burn so cut your nutes back by 200 ppm and you'll be fine
Ill just keep watering plain ph 6.5 water.
No nutes.
see what happends i guess.
Sulpher deficiency... im not sure. ill have to look that one up.
thx for the replys. Anyone else?
here is a pic of my jeti
Is there any leaf discolouration ? If there isn't I doubt its a defeciency. You already said your Ph and watering schedule is fine. My best 'guess' would be toxicity in one or more nutrients preventing uptake of another or the soil is constantly saturated preventing the roots from getting any oxygen. I could be completely wrong.
Hey UGU, what's your max temperature?
Oh yeah, if it's S deficient you should also see new growth pale and petioles purplish.
dont water as much
My max temp is 85 with a sealed room

no discoloration of the leafs. And its so weird. its just the budding leafs not the fan leafs that are curling.

Sometimes I wait till the plants wilt a bit due to lack of water. then i water. so im pretty sure its not overwatering. But I will do that again this watering. wait till they are wilting slightly then water.
u.g.u
our plants look a bit different. ur fans are curling too and they are discolored. my fans are fine, and everything is a healthy mid-deep green. But I will not fert for another watering just in case.
Great replys thx all. Anyone else have any plants like this or any clue whats up? Ill post more pics tommorow :thumbsup:

i had this same problem and jus put it down to high humidity/over watering. but could this same problem be caused by a lack of oxygen in the water?
