Bright yellow leafs??

Girls are in the 2-3 week of flowering
using Natures necture nutes/ in coco/ being drip feed on a recirculating system.

Have three different strains running and all are doing the same.

I'v run this nute line for the last 3 runs with great results. So I know the nute line is good.
I do NOT ph and their is no need to ph with this nute line.

The only thing I changed is I went with an Organic cal mag instead of calimagic. And our city water this time of year is treated to the max and has lord knows what in it. Normal is around 180ppm...right now it reads 340ppm.

basicaly my nute line up is
Natures Necture N-5-0-0 2ml/L
Natures Necture p-0-4-0 3ml/L
Natures Necture K-0-0-5 3ml/L
calmg-2ml/Gal

This yellowing is NOT normal in flowering, I do know the difference.

Nitrogen deficiency. And that's no surprise by the looks of your ratios, depending on how you dose the three parts.

I thought that at first but I see signs of N toxicity,



as I stated above this is my 4th run with theses clones and nutes with the same nutes profile. Tho last run I tryed pure flower bloom booster and got a little burn but as you can see their was enough N (all pic posted are from the same mother)




just odd after 3 runs their isn't enough N one would think I would have run into a problem long before this.

its not nitrogen def. Its iron def. iron deficiencies yellow starting at the base of the leaf. Nitrogen deficiencies start at the leaf tips then spread in a blotchy pattern.

foliar spray with kelp will help. Water with kelp or anything that has potassium. Anything with potassium will have plenty of iron.

I do see nitrogen tox. That will make yield and bud size suffer big time.

Bright Yellow Leafs
heheh... "leafs"

Thanks, I really thought it was iron... I guess my point above was the switch from calimagic to the organic calmag. The Organic has no iron were as the calimagic dose.
