I cant get rid of these deficiencies!

[Kegdas216]

Started with just 1 plant during early flower. Thought was cal-mag related. Fed cal mag… no change. Ph in soil is 6.8 to 7
0…tried feeding her more (gaia green 2-8 4 powerbloom) no change. Tried giving her some gypsum (soil somewhat compacted), no change. I give up. Its forever deficient.

Info -
3 gallon fabric pots, happy frog soil
Gaia green amendments 4-4-4/2-8-4 (1tbs per gallon of soil every 2 to 3 weeks)
Tap water left out over night 175ppm /7.0ph
Led lights - 800 par 18/6 cycles
3x3 tent
Humidity 55% day/ night
Temp 75f - 80f

How bad will this crap effect the buds? What am I doing wrong?

It could be phosphorus deficiency. But it has progressed.

Too much calcium or built up calcium in the soil can cause phosphorus lockout. How much calmag are you using? Did/do you use a P/K booster? It could be from lockout or just a lack of phosphorus.

I assume that the deficiency started when you pushed flower?

800ppfd at 18 hours is 51 DLI. You’re pushing them hard with the light. That alone can cause deficiencies if your nutrients are up to snuff. Cut back the ppfd or shorten the light schedule. Ease up on the girls a bit.

If your nutrients are not up to snuff with the light intensity.

Autos don’t care the light schedule, but they still respond to total light received during lights on.

I've only fed her cal-mag twice at 3 ml per gallon. I stopped using it when I noticed it kept getting worse. For a K boost, I give it seaweed extract from Sea Queen (15 ml per liter of water) as the instructions on the package stated, once a week.



The only P I'm adding is from the Gaia Green amendments, flower/bloom. I decided to cut this top dressing back to 2 weeks (instead of 3 weeks) because I thought the same thing, possibly lacking P. (3tbs bloom, 2tbs veg per plant)



As for the lights, I turned them down to around 625-700 PAR. Should I go lower? This puts me at around 42-45 DLI.

Yes, these deficiencies showed up about the 2nd week of flower. Oddly enough, it's only happening to 1 plant. The runt of out the 4. Which also seems to be producing the biggest and most frostiest buds. Which i guess makes sense.

as of today I noticed that same plant is starting to slow down on the drinking. Her water base was the only one that was bone dry today when I filled her up.

 

[Kegdas216]

Will these buds be saveable? Or is it a wrap for the 1 plant showing these issues?

If it was a fungus, wouldn't it have spread to the other 3 plants? They rub up on each other everyday when I check on them. The other plants look great.

I'd like to correct the first post. "It started with 1 plant" its only showing up on 1 plant**** the other 3 are fine. All 4 are runtz autos from the same seed bank.

Yikes, that’s a mess. With all the sugar leaves burned up (which is where a fair amount of trichomes are) I’d trash this plant and concentrate on your other ones.

Could be any number of issues. Happy Frog is primarily wood chips (and doesn’t dry out well). You could add a truck load of organic fertilizer but if you don’t have a living soil (microbes) there’s no way for your plants to update the nutrients you add. I’d guess that your plants really aren’t getting any nutrients. (You can also pretty much ignore pH and ditch the “bloom mixes” in soil.)

Unless you have a good handle on organic growing (which is MUCH easier in the ground/outdoors) I’d go with one of the bottled synthetics in the 2-1-3 range.

Yea i was thinking the same thing. Just ditch it and focus on the others. I might try grow dots next in just coco or hp promix. Seems easy enough and hopefully will stop this gnat issue lol.

Anyone here have any luck with grow dots in coco or promix?

Gnats ruin the roots and makes it looks like a deficiency, get some Bti like mosquito dunks or similar product, and let the soil dry out before watering, over watering makes the gnats larva thrive in the soil .. also a 3 inch layer of perlite over the top of the soil helps keep the gnats bastards out of the root zone.

Looks like you are paying the price for over watering and forcing too much light in veg. She never had the need to develop a root system.. until you water properly, you'll continue to have this problem in the flowering stage.
Good news, it's not rust disease.

If you look closely at your leaves that are being affected, you will notice that this is happening in your new growth. The lower leaves don’t seem to be as affected. This is a clear sign of an immobile nutrient deficiency. Mobile nutrients can be pulled from older leaves to support new growth, while immobile nutrients will only affect newer growth. If your watering schedule involves any dry back period it may only be compounding the problem. Organic soil should keep a constant dampness to it. Not drenched but moist. To me this looks like a calcium deficiency. The intestines of LED lights can cause your plants to pull more available calcium out of the soil than there is available. My suggestion is to lower the light intensity by dimming, if the light doesn’t dim raise it higher and that will lower the intensity at the leaves level, and try to find a readily available source of calcium for your soil microbes to break down.

I apologize if anyone here has already suggested this, I didn’t read every response. Hopefully this helps with your grow.

Your eyes are broken, sir.

You don’t say?!

 

[BearWater]

Can you elaborate, please?

 

[MartyMcFly42oh]

I don’t know , I can only see what was posted. I don’t see much of it on the lower leaves, but do see it on the mid and upper leaves aka newer growth. I took a screenshot of one of the pictures and meant to post as an example but forgot to. So I’ll post it on this post.

I see healthy green leaves lower down, and lighter affected leaves higher up. I’m just giving my observations. Not trying to mislead anyone or misdiagnose anything. Very difficult to asses someone’s grow with only a few pictures and a basic description of their set up. Either way just trying to help.

Too much water even tho I'm using the ac infinity water base? It only moisten the bottom 2/3 of the pots.. barely through wicking round cloth shoe lace looking things.

 

[Kegdas216]

I'm pretty sure my light intensity is what caused the issue. I wasn't dimming the light enough during the stretch. Since turning the light down to around 600-700 PAR, it seems to have stopped progressing throughout the plant. I'm still debating whether I should toss the plant or not. If the buds are still smokable, I'd prefer to keep it. The other three are still doing pretty well, aside from a couple of yellowing leaves that died off on the bottom, but I think that's normal being a couple of weeks away from harvest.

Here is a couple pictures. The soil stays pretty dry up top when using the water base so I don't think over watering is the issue.

Another pic of the other plants. The back left one is the one with issues lol. Either way, not all bad. 3 out of 4. I'm happy with that.
