Think Different, DWC. Mag or Zinc def?

[peaceloveandbud]

How's it going?

My youngest Think Different is having some issues. Take a look.

PH is within range, ppm at 450.

Looking like MG or Z def?

What is the best way to go about curing this? Ive got a bag of epsom salts, but if it is a Z issue than I am not sure what to do.

Thanks!

It looks like iron or potassium deftciency.Make sure your ph is right,correct that and give them light dose of npk with micro nutes especialy iron.Also you may want to add some cal-mag.Make sure your roots look healthy also and they are recieving enough oxygen.

As Namvet said :thumbs: Also i can see a bit of leaf tip burn on a couple of lower leaves Check your PH is on point and that your feed isnt too high

Nutes? Res Temp? Background PPM of your tap water? I'm inclined to just say pH but there may be more at play if you say it's within range. How often do you check pH?

Thanks guys! I don't have any cal-mag but I did add 2 tbsp of epsom salts and upped her micro/veg nutes. PPM is still at 5.7

She looks slightly better this morning. I am going to continue to monitor for signs of worsening and if that is the case ill flush her res tonight.

Peace.

I would try also to lower PPM a bit,

something like 350-400 PPM. how old are they? 2 weeks old?

i have spoted a purple stem at one of the leaves, mey indicate over feeding.

many deficiencies are caused by too much of other elements, not by missing one.
