Any guess to whats going on here?

any guess what the deficiency/tox is? PH is at 6.0 and PPM is around 715, i may lower the ppm back down to around 500 and see if the problem gets worse.

growing in DWC unit and using dyna grow liquid plant food, i mixed a bottle of grow/bloom 50/50 earlier this summer and have been using that because i havent had a chance to grab another bottle of grow. thinking it may be a p-k tox but im a bit unsure.

i also sprayed neem oil on it a few days ago because i had a yellow jacket hanging out, the neem oil coats the wings so it cant fly...so i sprayed it and then was able to kill it easier without getting stung.

I'd kick the ph down per scale

PH is not the issue..not going to develop issues in 2 days because PH is at 6.0 and not 5.8

A tox issue would only rear its head if ppm's were excessively high or if pH was completely out of range.

Question.

If you set the bucket ppm at 750ppm pH6. What does it test after 24hours?

i dont really set it, i filled up my rez and and ran around 500 PPM after the lil guy took root and started growing i increased PPM to around 700. PH has been reading between 5.7-6.0 for weeks now with no fluxuation.

using ditch master zone in rez as well. I have calibrated my pen and used a test strip just to double check and both of them indicate PH is in proper range.

also using tap water with a base PPM of around 350-400

from charts it almost looks like real early stages of MG/FE deficiency but my PH is in range for uptake of both of them. the dyna grow is supposed to have trace elements in it along with using well water i wouldnt think that would be the issue,

its 20 gal of water, maybe a 1/8th tsp or less of epsom salts? i dunno im at a stump here as like i said PH shouldnt be an issue at 6.0

I'm not overly concerned with your pH.

Its the increase or decrease of ppm which is what i would ideally like to know.

Your well water is quite high in ppm to begin with.

Do you know what its analysis is for minerals etc?

My tap water starts life at around 150ppm (0.2EC) made up of chlorine, nitrates, phosphates, calcium, magnesium, Flouride blah blah blah.

Something to consider is that excessive Ca can cause uptake issues and deficiency symptoms of Mg, Fe, B.

i could be off on the PPM i remember testing it a long time ago and it was high. it is well water.

ok so went and tested my PPM and it was 78, i guess i was way off.

like i said though im using a 50/50 mix of dyna gro bloom/veg so i guess now im thinking may be either too much P-K or a cal/mag issue...given the tap PPM is so low and i know there is chlorine in the water because we have a water system that requires the property owner to mix chlorox in with the water to sanatize the water before it is consumed.

78 is pretty good water.

Could be worthwhile bumping the ppm up to 200 with the calmag.

Then add your base nutes on top of that to around 500ppm or so.

Then test your ppm in the DWC bucket after 24 hours and watch what's happening to it.

If it decreases you can up the nutes.


If it increases then back off slightly eg 100ppm.

With such low ppm of your source water though I'm betting its just a Ca def starting as most nutes have enough Mg in them to sustain veg growth pretty well.

IRON-EYES
A-I'm getting high, and this is some sorta chattin web-ernet-y place y'all c'n' say shit

you think epsom salt would be ok in the rez, not much just a little? dont really have much for actual plant stuff for cal/mag i do have some supplimental pills that are for calcium and magnesium supliment for people, not sure if its broken down enough to work on plants though.

well went ahead and lowered the PPM to around 650, i know not much but....took one of the cal mag supliment pilss and disolved it into some water and added abount 1/2 of it, if shit starts going south ill empty rez and refill it.

It sounds calcium related to be honest so magnesium sulphate won't really help and could possibly make the Ca dec appear worse.


Stop adding extras until we see what happens to your ppm in 24 hours after you set it back to 650ppm.

not looking any worse this AM and if anything growth seems to be coming a bit faster than it has. I may still empty the rez and start with a fresh 400 PPM. going to look into a micro suppliment as well and get that ordered.

think something like this would be worth using in my rez full time given my tap PPM is extremely low for well water?

To be perfectly honest you should only really need to bump up the Ca and Mg content up to about 200ppm before adding your base nutes.

I didn't see the % of Mg in the jungle juice.
Ca was 5%.

Usually in hydro you only need 2% Ca and 1% Mg based on standard tap water containing Ca etc.

IMO it would better to get yourself a calmag supplement and add 122ppm of calmag to up your starting ppm to 200.

so you think i should just go with a camg only supliment? my issue is that i dont have a bunch of cash to spend on my project anymore. so if im going to buy something it would be more benificial to me to get a all in one so i dont have to concenr myself with buuying anything else down the road.

the dyna gro im using is supposed to have trace elements in it as well.

http://www.dyna-gro.com/3126.htm


as i said earlier the bottle i have is a 50/50 mix of the bloom and grow. they both claim to have cal and mag in them.

just a FYI the plant doesnt seem to be getting any worse and new growth seems fine...you think it could have been the neem oil?
