Is this nute burn or some type of deficiency?

I am thinking deficiency because I am running my PPM's super low (350). I am using the cutting edge 3 part and using Cal Mag. Any ideas would be appreciated.

It is much easier to spot deficiencies when there is a picture of the plant as a whole, not a picture of one leaf you removed. How do you expect us to know if it was taken from the lower or upper portion of the plant? For all I know it could be too little nitrogen...

Whats your PH? Are you using soil? If your in soil you want a PH of 6.4-6.5 if it is higher or lower you can lock out things like calcium and magnesium making the calmag you own pointless. if you are in hydro, I believe it is 5.5

I have used the Guild to Nut Deff and Tox reguluary.

Next time a picture of the plant does helps.

It could be... Mag or potassium... green vein with yellow flowers... but once again 1 leaf hurts.

are you using "plant amp" and "Mag amp" (which is cal/mag) from cutting edge or are you using another cal/mag?

I can probably help you as I use cutting edge

jpill, i'm using botanicare cal mag, I was using the six part system with cal mag and mag amp but my ph was always all over the place so i am trying this system. I am running soil and my ph is always between 6.2 and 6.5. I am getting that same leaf on the upper and lower branches. 2 weeks into flower

another pic coming

looks like mag def. thanks blg. I was halfing the required amount according to dosage reqs. those guides are helpful

Go back to mag amp and plant amp. The reason your ph was always off is because with cutting edge you are supposed add all of your nutrients *except plant amp, then PH it. Once your nutrients are ph'd where you want it *Then add plant amp and do not adjust the PH.

Plant amp has a low molecular bond that gives a false ph reading. you get what i'm saying? Look for yourself on cutting edge's website under plant amp.

Besides that you should be fine. ! I wouldn't use bontanicare cal/mag use cutting edge, CE's plant amp and mag amp are in a more broken down and readily available form (IMO).

PS. don't be nervous do just like i said. Mix all nutrients *except Plant amp, then ph to 6-6.5. After you have Ph'd *add plant amp and do not adjust ph just go ahead and water.!

Jpill, thanks for the advice. I think i will go back to the 6 part cutting edge, but after adding just a bit more calcium the problem went away. Now the plants looks healthy and not showing any signs of def. thanks for the input..
