tips of leaves are getting brittle

I am about a week into flowering. The tips of my leave seem to be bent down, and becoming very brittle at the tip. I am using florabloom in an E&F system.

Admittedly the only thing I have done differently is, I didnt let the water sit for 24 hours. It came out of the tap, I set the levels, and it hit the timer and watered the minions. I also did push the pH down to ~5.1, but it is back up at 5.6. The ppm is at ~750. Out of the tap my water is 240ppm.

Any ideas what they are trying to tell me?



I tried to get a good closeup.

Might be the begining of overferting. During the first week of flower, the plant is still in a transitional phase. Therefore it is not using alot of nutes. When she gets full blown flower, she'll soak it up. Just a guess though.

Looking at the leaves in background, I'd recommend that you flush you soil well to remove the Nitrogen build up.

Now that you mention it, I did go a little overboard on the transition phase. I never really got the ppm too high in the veg cycle. I only hit a little over 1000. They didn't respond well to anything higher than that. When I transitioned, they were already at ~1000 for a week or so. I didn't lay off on the flowgrow during the end of the veg cycle.

I changed the water, and added the florabloom at (tap water was 224, and i added 250ppm worth of florabloom.) So there are a lot of variables. But it was a pretty rough transition.

11/17: 474ppm <-- swapped to flowering lighting
11/18: 553ppm
11/19: 662ppm
11/21: 712ppm
11/22: 717ppm
11/24: 717ppm

I added some fresh water, because I noticed the water level dropped pretty significantly. I then re-adjusted the ppm to 716. I also noticed I wrote the date as 7/16, because I probably measured the ppm and then started writing lol.

And then today:
11/25: 743ppm

I added two more bottles of water to the rez to get the ppm to come down a bit. I filled a few more with tap water that I will add in 24 hrs to get the ppm down futher. I am aiming for ~650, but also hoping they will get used to it so I can push the level back up.

Thanks for the response!

I changed the water last Saturday. Can it happen that quick?
