Leaf Lesions and Curling (pics)

tiredofbuyingit said:

Hello. I've got an issue with one of my plants. Here are the specs

Day 23 flowering
Temps 72-80
PH of tap water -7
PH of soil - not sure. my soil tester sucks
Watering every 3 to 4 days
Feeding every other watering
1 gallon containers

The leaves on this plan are curling from the sides as well as the tips. The lower leaves are developing lesions that become very dry and eventually deteriorate the whole leaf.

Does anyone know what this is?

When you feed your plants ever notice that some of it accidentally hits your leaves. If so that could be your problem there, localized nutrient burn.

depends on nute strenght and brand. i do it all the time and have haver had a problem. but ya i have seen that with some. thats why i like organics, so much easier

Yeah bonz, the fans are on the same timer as the light, so they're on all the time. Calicat, I'm usually pretty careful about the watering. These plants don't have any foilage for about the 1st foot (i trimmed them about 2 weeks into flowering). I'm pretty sure it's nute burn, but I haven't fed the plants in almost 2 weeks and some of them are just starting to show mild symptoms of curling. I figured by now they would have all bounced back. Also the ones that have leaves that are curling aren't getting crystally like the ones that aren't. I'll make sure to get a couple pics tonight to show everyone. I'll either post them from home tonight or work tomorrow.

Just wanted to update with some new pics. The one plant that I've flushed (seen in the first 2 pics) seems to be doing better. The new leaves aren't curling and the old ones are slowly uncurling. The 3rd pic is one that I am considering flusing also, but wanted to make sure nute burn was the problem before I did.

The last 2 pics are of the rest of the plants that seem to be doing a lot better than these. Although leaf tips on the fan leaves of these are curling slightly the buds are getting pretty cyrstally.

go ahead it wont hur it anymore than they already are. on this one try to give it a 1/4 flowering nute anfter it drains about an hour or so. after running 2 to 3 gallons of ph`d water through then feed after she drains.
the idea there is that you just flushed everything out of soil so it has nothing to help it recover. so it needs a bit of a feed. then let it realy dry up between waterings, make sure yopu get run off every watering to

Cool Bonz. I'll flush the other 2 tonight and give them 1/4 nutes after the flush. Tonight is time to water and feed anyways. I'm using unsulphured molasses too. Should I start feeding them that again also?

wait for that, to much at one time. next feeding

Just to keep anyone updated that was following this post, the issue was def nute burn. After flushing the couple of plants they all bounced back within a week or two. Thanks to everyone for their help.

Also, just a couple more questions for the pros. I'm now at the end of week 6 and know it's about time to start flushing the plants. So no more nutes, but what about sups?. I've been using unsulphured molasses and didn't know if I need to stop that now too. The plants are looking great! I took some pics last night, but forgot my camera. I'll post them up tonight or tomorrow.

Also, when do the buds stop growing and just get more crystally? I'm just curious in trying to estimate weight. It seems like some of the top colas will be about an ounce, but they are really starting to get sticky and clumpy.

Thanks y'all

it`s hard to say what they will weight woth moisture instems. you can feed molasses right up to harvest but the longer you do the more of the molasses flavour will be in the plant

What does the molasses flavor taste like in the buds? It seems like a good thing.

depends if you like the taste of molasses.

i hear ya bonz. I like molasses, but not sure If I'll like the taste when smoking it, so I'ma lay off of it too. As I promised here are some pics of my girls. They are really starting to swell now. These were taken on day 41 of flowering. I'm really satisfied for my first grow. I just hope they taste as good as they look. I welcome any comments

they look great. good job
