The junk on the elbow looks like bits of coco fell thru the pot. Can you identify?
it was like a dark build up from the nutes i think, i have small holes in the top of those elbows from an experiment early on in this grow that didn't pan out so i turned them upside down and there is a small weep hole in the top now, it was like a concentrate of nute gathering there. i don't think it was anything to worry about.
Is it just me or is that water dark as root beer?
nah it's light.. deceiving photo in the bucket..
If there is contamination and it is still happening swapping out the res is not a long term solution. If the contamination is not happening any more it might help.
i understand, it's why identifying it is important to before i just do a change out.
Lets get
@Aqua Man and
@smoke in on this.
First post with pics is 180.
Steam!!
What is the actual leaf temp?
so i'm not a fan of IR guns, never had one that actually worked. i just bought this one last week, is an AC infinity measures all five things at once. i layed it in there for a while and opened the door and took these readings..
i can only assume these are my most current and correct parameters... (I guess idk) sory for the light photos that first plant is tough to see the screen.
left plant to right plant leaf temps are six degrees different from each other according to the POS gun. i bet i could aim it ten times in a row and give you ten different readings in a row... IR guns are fukin joke imo!
What is your fan placement and is it blowing directly on plants?
it is blowing directly on them, very light wind. it's on setting #1 of 10.. i only had it on to move some of the mist around a bit. i shot a video of it to show a better reality..
as anything been sprayed on the plant? In the room? Or anywhere that can be introduced through the intake? Eg cleaner like windex, pledge etc
no nothing since about two weeks before i even started the seeds. both cabinets were left open after bombing/spraying/cleaning. and right now the intakes are almost closed to try and keep the heat in.
In short we are considering the water source possibly being contaminated when the room was bombed.
Stoney how does the same genetic in soil look now for compare?
a current shot of the soil plant... still don't know what that bleaching was.. might have been from the foop foliar spray. this one and the two rainbow kush were a almost a week behind so i sprayed a couple times.
I can’t find that meter anywhere… if you have a link i just want to see how that particular meter works.
250 par is not bad if its a
View attachment 91037true full spectrum quantum meter
Why i ask.
not sure if this helps but the manual is only a few pages.. i don't know if we can upload a pdf..
if your rain barrel is thawed out now.
like a cow pissin on a flat rock!
My best guess is chemical contamination in the water.
i'm prepared for a change out. i mean if it comes back in a couple weeks there there's gotta be something leaching from the system. in which case would be total rebuild at that point.
Stoney is not new on this light. But it is spectrum adjustable. Could try pulling the red out but we are picking flyshit out of pepper if this turns out to be this genetic cannot handle red photons.
I went thru the same list as you. Best I can tell all the typical stuff has been addressed or was never an issue.
Looking forward to the response on if the soil plants are showing the same thing.
Maybe change the spectral ratio and see what the par is then?
Definitely can’t discount the chemical aspect only if it was in the water i feel we would see physical root issues. To me if its chemical its more likely airborne
i'm not opposed to trying this. normally i run a different spectrum with less red in them. i've run this straight spectrum before but that was then this is now.
there are more red diodes than any other in these light. most of the power comes from the red diodes.
i'm willing to try this. normally at this point in time i'm running just 40% red compared to the white and blue.. eg, 20r-50w-50b
Whats the height difference of the soil plant?
Just wanna say that no matter the cause the first corrective step should always be reduce light so as not to speed up progression of the issue.
The higher the light intensity the more demand on the plant. Thats not to say a healthy plant could not handle that par if its accurate.
so the soil plants are gen1 lights (two of them) the hydro side is one gen2... gen2 is said to be more grower friendly. i've been using them for a while now.
only a sheet of plywood seperate the two..
the soil plants have recently been topped for mainline. the three plants on the far right are the exact same age as the hydro plants, the rest are almost a week older...
the lights in the soil cab are at 50% right now and there are two lights.. 400w abouts...
i don't know how accurate my meter really is, i use it as a reference. at seedlings i don't want to get above 200. once i see five bladed leaves i keep it just under 600. once i flip i start to raise again.
just what i've done and no data to really show it just from gut growing..
Personally am confident on light intensity. Too many factors point that way. I don’t mean numbers i mean plant responses. Look at the petiole and how purple they are from anthocyanins, the expression of heat stress in the leaves. The extreme upward angle of the petolie,
I very much understand that the numbers if accurately represented by the meter would be upper limits for that small of plants but the physical responses say otherwise
i'll try lowering the intensity some more. i'll change the spectrum and give it a couple days... i honestly don't know what to say about the room numbers i just don't trust that IR gun. my controller data shows it more accurate i feel. this is data from the last week.. you can see the spikes once a day when i open the door. other than it's pretty steady. i have the leaf offset set to -4°
.
.
so with all that i'd love to hear your opinions and what i should do. i'm all for changing whatever to try anything...
Thanks!!!!!!!!!!!!
