You have a phosphorous and potassium deficiency.

Problems with Phosphorus being locked out by PH troubles
Cold wet soils, acid or very alkaline soils, compacted soil.

Soil
Phosphorus gets locked out of soil growing at ph levels of 4.0-5.5
Phosphorus is absorbed best in soil at a ph level of 6.0-7.5 (wouldn’t recommend having a ph of over 7.0 in soil) Anything out of the ranges listed will contribute to a Phosphorus deficiency.


Problems with Potassium being locked out by PH troubles
Soils with excessive Leeching and High ph soils and or water.Soils that are potassium fixated. An excess of kitchen salts (sodium) in the root system/environment.

Soil
Potassium gets locked out of soil growing at ph levels of 4.0-5.5
Potassium is absorbed best in soil at a ph level of 6.0-9.5. (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Potassium deficiency.

no i dont it doesnt fit because 2 plants are in soil taking floranova and 2 are in bubblers with hydro mix and there both doin the same thing? i dont see how that could be ...

[Boss]

hehe, I wondered about that after I dropped out the image :-)

Separate containers?

[Boss]

Better :-)

[Boss]

Whats ppm and temps, ph all that good stuff?

[nooblet]

i can only think that maybe the young leaves were burned at the same time as the water leaves but possibly milder i dont know if that even makes sense

[Boss]

It looks like a lot of nitrgen then some kind of lockout.

[nooblet]

i dunno the ph is good in the bubblers and in the soil just in case i made a new batch of neuts for the bubblers and hit my dirt with straight phed water well see

[Boss]

The three I see are in bubblers or soil?

To me it looks like it's getting hot in there. Temperature rises the closer you get to the light. In might be a cool 75 - 80 at the bottom of the plant, but 12" to the top it could be at 100 or more. Been there and done that in small growing area's. Check the temp. never mind.... the other ones look good and are taller......

the center plant is in a bubbler and just to its left and right are in soil the the one behind is also in a bubbler
