Leaf Curl... ph problems

Hey everyone hope you all are enjoying the holidays. I got this wierd leaf curl going on and I'm bot sure what it is. I'm think it might be a change in ph that did this but certain. I'm in a soilless medium and just fed at at ph of 6. Ppms were ~750 and this plant is 3 days into flower. It's not happening to all plants but most of them. I did get a new ph meter because my old one couldn't stay calibrated so That's why I'm thinking their might be ph issue. Any help is greatly appreciated, thanks

Have you checked for bugs?

i'm thinking that it doesn't like 750ppms. might try diluting down to 500 and see how she does

Thanks for the input. I might do a flush with a low ppm solution but I was giving 700 ppms in veg with no problem. I think my old ph pen was clearly off and when I watered with a correct ph it might of did something but I am not certain.

Just an update and a bump but I did a flush with lower ppms solution. The run off was a little high but I am not sure if it could be nute burn. Leaves don't get twisted like that when their is excess salt in the medium. Any who still looking for some input on what it could be. I'll take some new pics tomorrow.

A common problem with running low ppms is that not many fertilizers are designed this way, although npk may still be adequate you seriously short change the plant on some micro nutrients.

Food for thought if you have no luck after dropping the ppms.

Hey thanks for that, that's pretty intriguing. I did add some fulvic acid which has a lot of trace minerals. When I watered before this weird leaf twisting thing occurred I used a new additive from vegamatrix. It's the boost product from the company. I got it for free and I can see why if that's the cause of these issues. I even gave them the lowest dosage too.

Possibly you just need to start using a one part feed and drop the additives, my advice is limited but everything looks like its not feeding enough or locked out.
