Unknown strain need help diagnosing deficiency

On a side note....they look so cool like that.

But what else have you feed them? I'm thinking it's nitrogen.

Just bumping so someone else sees ya.

I use gh flora series. And they do look really cool like that. Im changin water as we speek gonna bump up nitrogen a lil

I hope that helps. There's a leaf chart you can find on RIU or Google that shows different leaf probs and what they're missing.

My signature line below may help as well... hehe
 
It could be nitrogen toxicity, it happened to me and it looked exactly like that. Light green/yellow starting from the edges and dark in the center.
 
It looks quite similar to this Zinc deficiency

Zinc
Zinc plays a roll in the same enzyme functions as manganese and magnesium. More than eighty enzymes contain tightly bound zinc essential for their function. Zinc participates in chlorophyll formation and helps prevent chlorophyll destruction. Carbonic anhydrate has been found to be specifically activated by zinc.

Zinc Deficiencies

Deficiencies appear as chlorosis in the inter-veinal areas of new leaves producing a banding appearance. This may be accompany reduction of leaf size and a shortening between internodes. Leaf margins are often distorted or wrinkled. Branch terminals of fruit will die back in severe cases.

Also gets locked out due to high pH. Zn, Fe, and Mn deficiencies often occur together, and are usually from a high pH. Don't overdo the micro-nutrients- lower the pH if that's the problem so the nutrients become available. Foliar feed if the plant looks real bad. Use chelated zinc. Zinc deficiency produces "little leaf" in many species, especially woody ones; the younger leaves are distinctly smaller than normal. Zinc defeciency may also produce "rosetting"; the stem fails to elongate behind the growing tip, so that the terminal leaves become tightly bunched.


Hope this is of some help.
 
It also may be Potassium toxicity.... have you been feeding any bloom nutes? They are too early in flower to be fed much, if any P and K, so if you have been feeding bloom nutes I reckon it could be Potassium toxicity

Its so weird because i have three different strains and this strains the only one that does it. The other girls are all green and perfectly healthy. I havent been pushing nitrogen into her. Ive been feeding very light.

It does look like it. I use gh 3 part and it calls for a lil bit of the bloom nutes during veg. This plant isnt in flowering yet.
 
If it is potassium toxicity it will show up as nitrogen deficiency, the catch is that you cant just add nitrogen and be good. The potassium will "lock out" nitrogen, meaning that even if it's abundantly available the plant will not be able to absorb it. I grow hydro so it's much easier to start fresh every week with a new reservoir. Haven't done too much soil growing but I know it's much slower to see effectiveness of treatments. I would say flush the soil and continue with a light feed. Hopefully someone more knowledgeable than my self will chime in. At first I figured magnesium deficiency due to the still green leaf veins, maybe just let her sit and continue with the cal-mag. Cal-mag is also a great form of chelated iron, which also gets overlooked as a micro nute. Hope this helped at all man, good luck!
Happy growing!
 
Phosphorus deficiency I think but I'm no expert here's a good chart to go by.

Yea it's probably nitrogen deficiency after looking at it again young plants need a lot that's what I've read flush then half the recommended dose water normal next water with just water then the recommended dose and I right

Yeah im thinking it has something to do with nitrogen. They arent getting crispy or any spots. Just losing all their color.

I run hydro so i just flushed and cleaned my res, and even'd the nutes back out. Cleared up in days...
So if i were you i would flush cut back on the nutes to her a little bit, and just wait and see how she reacts and go from there.
And the reason other plants wouldn't react like that one is, different strains/pheno's can handle different level of nutes. I have an Agent Orange pheno that can handle everything i throw at it, and others that are very sensitive and burn very easily.
