Organic Earth Juice Nutrients - Plant Problems

[Yadam]

Hi There, I tried posting this in the plant problems forum, but it was recommended that I try here because i'm using Earth Juice organic nutrients.


I keep having issues in flower. Every day my plants are looking worse and worse. I’m using Earth Juice Big 5 nutrients in a 2x4 tent. I have a HLG 260w 648 diablo light 24” above the plants. I originally thought this was light stress but I’ve dimmed my lights just below half way measuring around 22,000 lux and every morning the plants look worse and worse. Temps are between 77 and 80 during day and night, so it's not heat stress. I tried adding about a half gram of epsom salt per gallon to my last feeding and did an epsom foliar spray, but extra mag hasn’t worked.

I’m feeding the earth juice nutrients with every feeding per the instructions at a ph between 6.3 and 6.5. I’m entering my third week of flower and the plants will drink between 1.5 and 2L each, every 2nd or third day depending on how wet the soil is.

I'm following the instructions on the Earth Juice bottles i'm mixing about 4gals at a time using the combinations below;

All these amounts are the totals i put in about 4 gal of RO water.
2 Tablespoons Grow
2 Tablespoons Bloom
4 Teaspoons Mirco
4 Teaspoons Xatalyst
2 Teaspoons Meta-K
1 Tablespoon Cal/mag
1 Tablespoon Liquid Seaweed

I'm also aerating the nutrients at least over night to naturally bring the PH up.

Feeding every other day or every third day. I'll feed 500ml to each plant, wait 15 to 20 min then keep going until I see the plant saucers start to fill up. Usually it's been between 1L and 1.5L per plant.

Any ideas or suggestions would be greatly appreciated. I’m spending a lot of time on these ladies and they’re not showing any love back.

Maybe add what is your base soil and what your water is.

Hey thanks @myke.

Water is from a stealth hydro RO unit. I use the same water and nutrients for clones/veg and don't have any issues. It's only two or three weeks into flower where I start seeing this weird browning almost burnt looking on the fan leaves.

Base soil is FF Happy Frog mixed with a 20 to 30% ratio of perlite. I used about half of the soil from my past grow and half new out of the bag. The reused soil had the same mixture of perlite, used the same organic nutrients however, the issues i'm starting to see this time around looks a lot what happed during my last grow. I don't think it's some weird plant disease, but something is off and i'm spending so much time trying to figure out what's going on. I'm about to abandon organics or semi-organics all together.

Download that pdf file and have a look at the pics, I think yours looks like calcium deficiency but I could be wrong

Essential plant nutrients are needed at crop-specific concentrations to obtain optimum growth or yield. Plant tissue (foliar) analysis is the standard method for measuring those levels in crops. Symptoms of nutrient deficiency occur when those tissue concentrations fall to a level where growth...

I also have two co2 mushroom bags in the 2x4 tent but I doubt that's what is causing the issue. I have the bags strung on one side of the tent and 6" filter attached to a T6 cloud line fan on the other with hot air vented outside. A 4" cloud line is also on the bottom pulling air into the tent.

From the pics in the study it looks to me like calcium, the only other one that looks similar is manganese toxicity.

 

[Yadam]

thanks @JustBlazin. So you think the fix is just to add more cal/mag?

 

[JustBlazin]

That's just what the pics looked like to me when I compared them to that study, but it looks like you are putting 15 ml/gallon of calmag wich is 10 over what they say to put in on there bottle so I'm not so sure.

 

[Yadam]

Hey @JustBlazin those nutrient amounts are total in 4 gals of RO water. So i'm putting in less than a teaspoon or around 3 to 4mg of call/mag per gallon.

 

[myke]

Have you tried removing the xatalyst or meta K?

Edit. Do you add this stuff in veg? You said only problems once you go into flower.

 

[JustBlazin]

I usually think it's a potassium deficiency when i see the edges of the leaves all crispy like that but it should start at the bottom and your bottoms still look green I think

 

[JustBlazin]

That seems low since your in RO water, I think it's 5ml/gallon of water

 

[JustBlazin]

In ro I'm pretty sure you want more than the recommended does of Calmag, I guess they take into account everyone having calcium in their water that the ro filters out, so you need to put more

hey i haven’t tried that. I don’t use the meta-k during most of veg but I do start to add it a few weeks before the flip without issues. I use the xatalyst during the whole grow, but in slightly lower amounts in the beginning.

hey yeah the bottoms are green, i do trim a lot of the bottom before the flip though.

well thanks for the help. I’ll try adding a little more k and cal/mag during my next feeding and hope for the best.

I would ditch them both. My thoughts are if there’s not enough stuff in the grow,bloom and micro. Then use a different kind of fertilizer

 

[myke]

If you read about the meta K. It says for when you need more. Do you need more? I should hope not. You already have bloom nutes.

The problem is your soil mix has become inactive. Microbial activity is what governs ph in organic soil which is why giving npk is not working. Adding worm castings as a top dress or even better brew it in a tea will help your mix begin to work again as it should. The alternative is synthetic nutes...

I know you're bubbling it first. But are you adding a pH up after you bubble it to get it around 6.5? If so, what are you using?
