I know I am still a newb but to me it def looks like nutrient toxicity. You need to flush the grow medium with 3 times as much water as the pot your plants are in. I have had leaves that look exactly like that, that was before I bought an ec/ppm meter

thanks for the help guys, i looked at the plants today and i noticed that the plant with the curled leaves had a branch on it that had on few male pollen balls on it, i removed them from the plant, will the grow back? and if they do if i keep taking them off the plant will it keep seeds out off my bud? i changed my water on thursday and used my nutes (fox farm line)at 1/2 strength, i had been using full strenght for the whole grow and in week 2 of flowering i noticed some burning on the top fan leaves. Vi helped by informing me to lower the nutes down to 1/4 to 1/2 strenght, thanks again for the help Vi.what should i do to fix these problems? h2ofarmer

hey man, I had a med size chunk of my plant do that to me on my last grow. for me the leaves never recovered, and the buds associated with the leaves were smaller. my problem was that it was too hot. The upper most part of my plant got damaged from the heat coming off the light. I adjusted my light and the rest of the plant did not succumb to the same damage.

I don't think is heat problems, i use Florescent and they are cool to the touch, and my plants are curling, i think the problem is the water, they way i fixed mine was to prepare water on 2l bottles and leave them outside for a day or two exposed to direct sun light, i read somewhere that UV light will help purify the water, another thing i do before giving that water to the plants is boiling the water then letting it cool, once its cool feed your babies. thats what fixed my problem, i hope it helps

It's almost certainly nitrogen toxicity. Too much nitrogen will cause leaves to have a deep green color and the tips to curl downward (aka. ram horn). Too much heat, on the other hand, will cause leaves to curl upward. The outer part of the leaf dessicates faster than the inner part causing it to curl up.
Some people are surprised that they have nutrient burn especially when they are running a fairly low EC. However, aside from simply just having too much fertilizer in solution, two other factors can cause problems. One factor is increasing the nutrient strength too quickly. Plants can take a lot more nutrient when they are introduced to it gradually. The second factor is too much nitrogen regardless of EC. If you give a plant a 600ppm solution of 90% nitrogen, you will burn the shit out of it, whereas a balanced nute mixture at 600ppm will, in most cases, be fine. Back off the EC a good bit, and make sure your solution is well balanced (eg. calculate the N-P-K ratios to achieve approx. 1-1-1 for veg and 1-2-2 for flowering) |
