What Kind Of Deficiency Is This?

[dieseldawg2480]

This is mostly on the fan leaves more in the middle to top. I'm using coco with general nutes. Using RO water and with a average of 5-600ppm range. No higher than 800ppm fed daily via drip. The runoff has not exceeded 1100ppm. If it does get in 1000ppm+ range I flush with lower ppm range 3-500 until I'm getting runoff near what I'm flushing with.. @Seamaiden

Potassium deficiency, I think

I was thinking iron or zinc.. My ph is within range 5.8-6 everyday. That makes me think it's not either of these ^^ . It's only on a few different phenos but getting worse daily..

Hydro or soil/soil-less mix?

Coco ^^ it's not just the lower or middle of the fan leaves. The whole plant. I'd take a body picture but it's trellised

Coco ^^[/QUOTE

Coco ^^

Are you adding any cal-mag, since you're using RO water?

Of course I'll take a whole plant pic

Is there any chance its floro burn?

 

[dieseldawg2480]

Floro burn? @scarecrow

Like burn from your lamps.

Like burn from your lamps.

No cause it's on lower leafs as well. That are not getting as intense of lights. I have others that are closer to the lamp that are not showing burn.

Potassium deficiency

Could be wrong but looks like a Mg issue. Possible Zn as well.

Here is an excellent write up on nutrient deficiencies and pictures to better understand just how difficult it is to really accurately diagnose nute issues as many can mimic each other. Its a pretty in depth read but contains valuable information to aid you.

I would say mag too... cal/mag binds to coco making it unavailable to the plant. Looks like you need to cut back on the nitrogen and use more pk also.

They do look dark from to much nitrogen. The color from the picture is darker than in person. I have multiple strains and phenos on the same Rez some of the others are lighter in color. It's difficult to make them all happy and dialed in on the same nute schedule. Here is what on that table..
Uberdawg - Chemdog D x Chemdog 91
Stardawg91 - stardawg x chem91bx
Cookie tang - forum x sour tangie
Buckeye purple- dosidos

Ahhhh the hassles of running multiple strains in 1 fixed closed loop system. It can be a challenge, epecially with diff strains needing diff levels of nutes!!!! Nice lineup BTW.:):fire::fire::fire::fire:

Good to see some familiar faces on this forum @jumpincactus this place has been a ghost town for awhile.
