Leaf tips curling

[dexorated]

The tops of the leaves at the top of the plant are curling, what is this from?
It's a 4 gallon pot, all organic soil, clone about a month old, 400w hps light, no ferts used, and the soil is about bone dry. Thanks

Looks like they're not getting enough water. Although, this isn't coming from experience...


"If the tips of the leaves are curling down, and it is limp and lifeless, it's not enough water. If the leaves are curling down, even at the stipule, but are firm, it's too much water."

I'm probably going to go ahead and say that it's not enough, though, 'cause it's a 4 gallon pot, and those plants don't look too big.

Thanks, I gave them a good watering today

how are the tips now dexor?? b1

[dexorated]

still the same... tomorrow I'm going to try adding some nutes I got and see if that helps

[b1v2w3]

I'll be watching. Pics? b1

What about heat>>400watts is HOT. how far from the leaves, using ventilation/heat extraction fan. b1

[dexorated]

My heat is fine... i have a thermometer right at the top of the plants and it stays between 76-82. I have intake and exhaust on the lamp and a big 2 foot intake fan in the box.

They're still not looking better. I've tried turned the fan off, moving further from the light, and adding nutes.

here's a pic, for some reason it's only on the top leaves on all the plants

Pot too small?? b1

[dexorated]

I don't think so... they're in 4 and 5 gallon containers. Those are suppose to be big enough for up to 5 foot plants. Mine are barely a foot.

[b1v2w3]

well........ I'm stumped. so far. b1

What kind of ferts are ya using,how often,and in what kind of medium?

[dexorated]

I've only added ferts once. It was Fox Farms Grow Big Liquid Plant Food. 6-4-4. I added a 1/4 tspn to a gallon. The tips had already curled down before I added the fert though. I feel like I've adjusted every variable, but they still stay the same. Not getting worse though, it's just the top one or 2 nodes that have the curled down leaf tips.

[meangreen]

I cannot give you imput unless ya answer my questions,what medium you growing in,how often ya watering it and container size.The pics you supply are not that great,but it appears to be overwatering.

[dexorated]

it's in organic soil, I water when the soil is a dry 3 inches down and I also have a moisture meter. Pot size is 4 and 5 gallon. Would you like a pic oif the whole plant or what?

[dankygrower]

I wouldn't worry about it,my plants do the same thing sometimes and they tend to grow out of it.

[bamagirl77]

i have the same problem no nute deficency or water but they are still like that but are flowering just fine i think it is in the strain.

[Mud_Hunter]

Pic looks like one of my plants...exact proplem. You may have over watered but didnt know because you didnt stick your meter ALL the way down deep. Aslong as you have a grip on it now...dont worry.

PS: My leafs are stilled curled...it takes time!

i think you got a watering problem either underwatering or overwatering.
