Can't get it right, nutes

[mrpuffins]

So I implore anyone really hoping to help to skim the short time line in my journal and I believe there you will see the problem truly unfolding

In short, any time I add nutes to these ladies, 1/2 or even 1/4 strength I seem to get burning across the board.

Pics below are 1 week apart after a full res change. Using half strength, actually even a shade less.

Now in addition to the burn I see addiction bunch of DISCOLOR?

really at my wits end and look for any help, again, please use my journal for context so any help offered is well based.

Thanks in advance crew!

Seems like your problem is the source of lighting here...try a 2 foot T-5 light so the plants have more energy to eat the soup...

 

[chemphlegm]

what "nutes" are you using? have you tested your water ppm?
what light/temps/humidity do you maintain ? do you have a ppm meter? what does your
res read with "quarter" nutes?

 

[Final Phase]

I have way more time on my hands than I need to get my work done... I actually read most of your journal. Your enthusiasm is top notch. It sounds like you have growing fever. You're doing great for a short run - The problem is this ain't a sprint race it's a fucking marathon. Good luck and have a great time growing yer herb...

Advice? The only thing I can think of is to make sure the plants have good drainage. Improper drainage will get you fungus that will bring fungus gnats. That will start yellowing at the bottom of the plants and leaves die off - fucking up the yield and ending up with tall jacked up plants...

Have fun!

Still playing with light options, you can see I had a six bulb set up before but I cannot agree this is ligjt related

Using general hydro 3 part

Yes I have a PH and tdm. And keep a close eye

Temps fair, little high but not terrible, acceptable res temp, played with PPM from 200 up to 600, they all seem to bring burn after a few days.

You can find most of this in the aforementioned journal

Always been a passion, thank you. I have no rush, it will be what it will be, but this is just escalating.

I drain and wipe out the res so I know it's clean. Had some alge in the beginning but all gone now.

Can you post a pic of the roots?

The "burn" looks more like rot. Lower older leaves yellowing and dying. You'd see nute burn all over, especially top growth... but yours is lush and healthy.

Either way, your lights aren't helping... the plants need ample energy to recover from their stresses.

Are you using any supplements in addition to GH 3 Part? ... like an enzyme, or bennie product?

No supplements.

Roots look good, not slimy or smelly...but it did get me thinking...

Res is pretty small, about 1.5 gallons due to it being a stealth box, do I need to prune the roots back some? They look healthy and don't think there is any lock out going on (also as the plants response is always with a res change.

Bump, still looking for some thoughts....

I have been using fox farm ocean forest and happy frog with great success only using 79cent r.o water from the store, use light nutes every other week and watering as needed and I no longer run into problems. It's a beautiful thing. Also using fox farm grow big for veg and big bloom for flower.

I think you have locked out cal. What are you using for ph up/ down.

I checked out your journal, and you could benefit from adding a y splitter so those CFLs are diagonal or replacing them with 19w LEDs with the defuser removed .
I have a diy light I built with three cfls and two LEDs it works great. Of course I mixed the spectrum like you did, so you're on the right track.
And I have a pretty good idea what's up with your nutes, but it is only a hunch till I get a little more information.

 

[mrpuffins]

General hydroponics brand.

I wonderd this, but how? Root mass is pretty big....

What you thinking?

 

[im4satori]

I have not looked at your journal...
I think you have a couple things going on

most of which is deficiency from under feeding

those plants are large enough to obsorb a full strength nutrient ratio

feed you GH 3part 6ml gro- 4ml micro- 2 ml bloom

second thing.. I think you Magnesium deficient... are you using Epsom salt or a cal/mag product?
the twisting and torching of the leaves is clear Mg def and the margins rising on edges of leaves as if leaf was a canoe or taco

I don't see calcium def which usually presents as red rust colored freckles so you might have enough calcium in your source water idk
therefore you might be able to get away with only using Epsom salt and not cal/mag since you may not actually need the calcium

GH 3 part is notoriously low on magnesium almost always requiring additions...

last... I might have spotted spider mites! do I see small tiny white pin hole sized white spots on the fan leaves? or is it just my eyes?

try using azamax combined with silica mixed together 1x per week
itll help with your pest and work against mildew

give them a quick flush with ph'd water and begin feeding full strength

Alright I was having some issues that looked like like yours , and I made some pH down sulfuric acid. Slowly add distilled water to sulfuric acid till you make a 5:1. Or10:1. Or 25:1 or. 50:1 ratio depending on how much water nute solution you need to pH.

When I added my calmag and my pH down in the same day the calmag would precipitate out.
@Yesdog helped me to make my sulfuric acid based down and never a problem since. If your interested let me know and I'll explain in detail

The biggest problem I have with reaching this conclusion is the reaction any time I feed them. If I go longer between feedings they look fine, but within a day of adding some the burn look starts.

But I am at the point where I have exhausted other paths aND just ordered a calmag supplement. Also going to using distilled water from now on, I think my water is too hard.

Thanks for the contribution all!

[im4satori]

feed them this

6ml per gallon grow
4ml per gallon micro
2ml per gallon bloom
2ml per gallon calmag
1 gram per gallon Epsom salt

that's about 0.7 to 0.8 EC...(600ppm to 700ppm) no way those will be burnt buy that and its a perfectly balanced ratio
