Leaf Lesions and Curling (pics)

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?

It looks like nutrition burn - hence the really dark leaves and leathery appearance - since you are flowering now all you have to do is cut out the nitrogen, well you can cut out ALL of it for a while, maybe even two weeks and up the Phosphorus and you want to up the potassium a little slowly too - maybe lacking a little hence the curl. That happened to me too. It kind of made the final flower weird, like darker, less plump, and took a lot longer to flush so you want to correct the issue before that happens.

Introduce small amounts of nitrogen again slowly. A very small amount or the plant will shoot up again and grow more. Plants need nitrogen through their whole life cycle but all you need is a minimum amount.

All they above mentioned and give her more water, I don't think you are feeding her enough, this is summer and if she's getting big she will take in alot more. try feeding/watering everyother day, or just a sip between watering/feeding

Thanks y'all. Poptherock, I've looked at the plants and soil pretty closely and haven't seen any bugs, but I'll check again tonight. Livevibe, you are right that this plant is a little darker than the other 9 I have flowering, but the buds are bigger than almost all of them at this stage. I've been feeding with Miracle Grow 15-30-15 (i know this isn't the best). I'm going to get some Tiger Bloom when I get a chance to get to the Hydro shop. I've also been feeding with 1 tablespoon of unsulphured molasses per watering. I thought it might be nute lockout from a ph issue so I gave a teaspoon of hydrated lime yesterday and no nutes when I watered.

Just wanted to update on this issue. I think now there are 2 seperate problems. The leaf curling being one and the leaf lesions the other. I'm fairly confident that LiveVibe was right about the curling happening due to nute burn. I've cut out the nutes and they seem to be uncurling a little. Some of the other plants started to show the same symptoms and they're getting better too. As far as the lesions I'm still not sure. Any more suggestions would be awesome.

It's an indoor grow. I've stopped all nutes for about 10 days now and I'm using FF ocean forest soil. I flushed the plant that was the worst about 3 days ago, but the leaves are still a little curled. I'm going to give it a couple more days. On another post I saw that the issue could be the pots are too small. These are 1 gallon pots and have been vegged for 5 weeks. Some of the plants are over 4 feet tall. I hope this isn't the issue

did you use 2 to 3 gallons of ph`d water to flush. do you ph your nute mix just befor feeding them? do you foliar spray with light on?
the leaves wont come back, as long as the new growth is good you should be ok. i would recomend getting a better ph tester for the nutes, even an 8 buck liquid one. untill you do i wouldn`t give nutes

yeah, I used about 3 gallons to flush. My tap water is right about 6.5 ph. I haven't foliar sprayed since flowering started. Today will be the 3rd day since I've flushed, so when I get home I should be able to tell if the flush is helping. Thanks for your info bonz and I'll keep you updated after i get home tonight

let it dry up good. it should be as light as when you first planted it. then water. after the flush you need to start at 1/4 nute mix again and bring it up.
if you did your foliar when the light was on that could have burned the holes in the leaves, always do it with light off. i usualy feed with 1/4 nute mix an hour after i flush. you need to replace the nutes in soil that you just flushed, but wait till next watering this time.

It's a 600 watt hps cool tube with a 424 cfm fan pulling and a 250 cfm fan pushing air through the tube. The plants are about 6" below the tube, but this one isn't directly under the bulb. The temps stay about 75 degrees and I'm pretty sure heat isn't the issue
