those #'s tell me exactly everything I need to know
and exactly what I said along time ago
the purp is being over fed
the sour jack underfed
because they are so different it will be impossible to even everything out
the purp I would lower ppm to 600
the sour jack I would raise to 800
from what you are feeding now
that would mean 2 res
which isnt ideal or probably even optional
so
if you can maintain a proper moisture cycle for you plants you may be able to get away with this predicament.....
another huge problem is your temps at night
you cant drop below 65f
it will greatly effect your plants growth
and a temp of 55f will actually stop your plant in their tracks
Not Good!!!
as for discoloration
NOT N DEFICIENT
N def starts at the lower leaves and works its way up
the yellowing on your plant has always started on new growth...
to me it looks like a Sulfur Def
for the next week I would like to to get a bag of epsom salte from the local grocery
to a spray bottle Add 1Tbsp mix well and apply as a foliar to the Sour Jack
spray them once every 2 days
we need to see if this works before we figure out the feed situation
This is the big reason to not run multi strains imo unless you want to have problems.
The problem I have with this tho, is when he raised his ppm he got over nute symptoms, so im hoping that your epson salts does it.. I asked him if he had any calimag, and bicky mentioned sulfer.. But then why is the purp staying so low on ppm, if its getting overfed...
Something still dont add up to me.. hopefully the epson salts will work.. Wow, im glad I dont seem to have them issues, but then again I ve stayed close to same genetics, usually csi, and usually something with cookie in it, or urkle...
Edit: I meant purps, which he said was down at 650 and sour jack was at 850 and he was feeding 700...
Wouldnt that mean he is getting salt build up in the one at 850(sour jack),
and the one at 650, (purp), which is slightly under what he is feeding, be slightly closer to what we should expect?
If the sour jack at 850 is getting nute burn, then I beleive he had salt build up,
and that flush ought to take care of that.
So hopefully im right on the flush, and your right on the Sulfer diff.
Me and you here,,, So why do you think he is sulfer diff? When none of us ever are? It has to be A. Strain or B. Parasite in the coco?
I know most of the times you say just up the base, but I think at times some plants are too finicky, are grower watering error, but that just doesnt work.. However I haven't seen many times when we had to add some extra micro nutrients. Calimag at best..
