Yellow leaves, nitrogen defficiency or too acidid?

[New Age United]

Ok, I have two plants that are yellowing like crazy, I am using soiless medium, I have given slow release nutes and am feeding them MG premeasured nutes once every two weeks. Four out of six are doing just fine but two are yellowing bad, I bought some lime stone today and am just wandering how much I should mix in the soil, it says one 15kg bag per 1000 sq ft but they are still in one gallon pots.

Gonna have to bump this up

No opinions? Anybody, I guess I will just have to experiment myself, I'll just add a couple tablespoons of lime and see what happens. If anybody has experience with this it would be much appreciated.

i would guess nute burn

Maybe I will try cutting back the nutes on these two, I guess I'll have some mad science to do with these guys.

It looks like it could possibly be high Ph but Im not sure thats kind of a guess. Anybody agree or disagree???

It could be for sure, I have tried baking soda with no results, I am turning to lime stone, hopefully it will help.

no matter what it is

your safe bet is to ph balance enough water and flush the soil out complete ......start it back on 1/2 str nutreints ...and get a soil ph meter

I got both a soil meter and a water meter for ph, I am taking it much more seriously now. I have heard that MG is very acidic and this could be the problem.

ph balance the water to base 7 and flush say 3/4 of the full amount and that should get u about 6/6.5

u will lose some time on this ....be last one u gut and dry



no matter what they say check the nutruient feed's ph balance...........personally i do 2 feedings at 6 and then 1 feeding at 7 then 2 at 6
