Hi everyone, I'll get right to it.
I am in the my 2nd week of flowering, and my Nordle (CBD trial) has come up with veiny leaves. The leaves are still green, no curling or browning, just not as wide, thinner, and they appear 'veiny' thats the best way i can describe it. Ive had this issue before in soil, but it was due to high PH. I've checked my levels, and they remain steady between 5.8-6.2 (In hydro, dwc). I am using Lucas formula in a bottle (floraNova).
After doing a simple search, supposedly its a zinc deficiency. I went to the hydro store, they had nothing for zinc, but after wa quick serch there, he said that some people put in zinc washers in their rez. ive done that, its been a day. Will this work, if this doesn't, what am I missing? Is this even a Zinc deficiency?
Here's a pic, thanks! Help!

Rarely does one get (Zn)def with out the other (Fe) and (M n) def's, , these are immobile compounds and like you and the canna plants can easily do without ....without causing any serious damage to yourselves,
the veiny leaves, you see are thick fat and prominent veins that you have been over watering these plants or if in DWC, not enough air in the rz..check it out !

IMO- Phosphorus, and Magnesium deficiency.
If
pH is good-
PPM are good-
Nutrient solution temp is good-
You should be good.

Are your roots looking good?

I think I'm going to add cal mag and see if that helps. my roots look awesome, I dont think I've had whiter roots ever. my rez gets tons of air, I'm using dwc from modularhydro, dunno how popular that is, but it gives tons of air like 1000x better than airstones (ok, maybe I exaggerated, but still ridiculous bubbles!)

Thanks for the helps guys, and I'll let you all know what happens.

most 16 penny galvanized nails are coated in zinc, take a file and scrape off the zinc into a powder, sprinkle on the soil, or let it sit in some water for a few days. looks like a number of micro nutes locking out at the same time.

not sure if it is zinc but check this out...https://www.icmag.com/ic/showthread.php?t=11688

I went through the link, looks more like sulfur than magnesium because the yellowing goes outward. The stems have gotten noticibly taller (early floweer), but also stiff. So I went with botanicare sweet raw (insteade of calmag). 1.5%Mg and 2% sulfur. Ill let you guys know how it turns out
