Add cal/mag

It definitely looks like it is needing cal/mag, but I would also go to the hydro store and get fresh calibration fluid and calibrate your PH meter as It looks like the PH is not right. It has been my experience that when plants look like there are several types of deficiencies at once, that is coming from PH being off. I would verify that my PH meter is measuring correctly, but I would also add some cal/mag, about 5ml to a 5gal DWC bucket.

sweet thank you guys cal/mag was a suspect ill pick some up in the morning

What level of nutes are you using? how old are these plants?

 

[pcduck]

Just seen your pH..

I would lower it to 5.5-5.6 and let it drift up to 6 before adding a fresh batch of nutes.

:yeahthat: I forget that with GH nutes and hydroton, the PH will go up rather than down, so you need to set it lower initially.

any change?
