This is the "Base"

The drop I put in was Bio-Genesis: Mineral Matrix

Guaranteed analysis:

Soluble Potash (K20) 1.0%;
Water Soluble Magnesium (Mg) 0.5%
Sulfur (S); Combined 3.0%
Boron (B) 0.02%
Water Soluble Copper (Cu) 0.05%
Water Soluble Iron (Fe) 2.0%
Water Soluble Manganese (Mn) 2.0%
Molybdenum (Mo) 0.0005%
Water Soluble Zinc (Zn) 3.0%

derived from Langbeinite, Sodium Borate, Copper Sulfate, Ferrous Sulfate, Manganese Sulfate, Sodium Molybdate, Zinc Sulfate, Citric Acid is used as a chelating agent.

"BOTTLE SAYS"

For soil and soilless potting mix applications, use 1 teaspoon per gallon (5ml per 4L) along with your starter or transplant nutrients during planting or transplanting and soak media well. Or use as a supplement to a complete nutrient program, at the rate of 1 to 3 drops per gallon. Or add 1 tablespoon per gallon (15ml per 4L) and apply as a media drench to correct deficiencies. Repeat as necessary.

That's a hell lot of sulfate there........

Dude, those directions are fucked! Literally; cannabis don't need that dosage by far, let alone that is a lot of micros........ sulfur, iron magenese and zinc, that is where the toxcity is coming from.... that is a ton of micros dude.....

I would use 1/4 to 1/2 teaspoon weekly every 7 days.

You will need to flush it out, Still I am thinking the sulfur is what is possible causing the yellowing of the top part, too much of it; it's hard to see which kind , but normally when you have too much of something; the colors are reversed rather then the colors are of a deficiency is.

So since sulfur is on the petiols outwards and affected the entire leaf, the yellowing on the top is affecting inside only from petiols outwards and with all the sulfates that is in that bottle I am guessing it is being caused by that since this problem is acting like a sulfur problem but reversed.

I would flush them out if I were you, get rid of all the junk built up in there and not feed that dosage again.

I would use that once a week tops at 1/2 teaspoon per gallon until they get bigger.

the rest I would use 1/2 teaspoon per gallon and not use the LK for now if I were you.

FYI..I never gave them the Mineral Matrix before, ONLY THAT ONE DROP mentioned...Other than that the only Micros they are getting are from the "BASE" as pictured above.

I am talking about the base, not the matrix......

I flushed them tonight and I was getting between 400-475ppm with 110ppm water.

I have other nutes(EJ) that dont contain Micros that I will be giving them next feeding.

Also note that it's hard to tell when you burn plants with organics since they have low conductive properties.

Well things dont look to good again....i tried to not feed anything for a watering cycle..then they started to look like they did before.

March 24 Box temps spiked(Warm day) to 90F..Plants wilted

March 26 feed.

1tsp EJ GROW, 1tsp BIO-Grow, 1tsp Catlyst
Readings after mixing 450ppms @ 4.6

Daily temps are 79F-81F now....RH is 20%-30%

I just cant win this year...

 

[MynameStitch]

Go ahead and feed them then, how often do you water? How big are they now? You got updated pics?

 

[icky420]

I havent got to update this because I was off fighting Algae with my clones....

Now that I am better focused...Onward.

Here is a pic of 1 plant..They all look like this.

I just transplanted about 5 days ago into the 6in squares.
I Mixed 50/50 Happy Frog and Light Warrior with about 1/2tsp/gal Powdered Lime
