Problem with one plant out of the garden...

[Jahminded]

Hey Everyone!!

I'm having a problem with one plant in my garden. I've got a Bubba Kush run going and things are looking very green and lush with those girls. I took in a stray plant early in veg, not sure what strain it is, but it is having some issues. 32 days flower for the lot.

Here is the rundown...

Soilless mix for all
PH = 6.0
PH Runoff = 6.2-6.4
Room Temp = 68(night) to 80(Day)
Under a 1000W HPS ...about 24 inches under

I have been feeding all a bloom mix of about 800ppm. PBP Bloom, LK, Sweet and some Cal Mag because my water is pretty soft at 80ppm. They are watered about every 3 or 4 days. Soil runoff is within range depending on if I just fed or not.

Because the soilless mix I use has nothing in it I typically feed every other watering.

I'm thinking this strain has a lower tolerance to the ferts than my others and perhaps that is why it is acting up. This all happened within the past 10 days. Just thought I would run this by the group and see what others think. Thanks for taking a look.

Here are the pics. Forgive the quality....they are from my camera phone.

Ph in soilless should be 5.6-6.2 including your runnoff. Looks like too much of something.

The only thing I can think of would be the Cal Mag......but considering the softness of my tap water I'm just not sure. Maybe tap water at 80ppm does not need supplemental Calcium.....At 800ppm I wouldn't think the overall nute level would cause this....especially with the rest of the plants, again a different strain, are thriving.

buildup of salts there

flush out your nutrients

you using soft water? water from a water softner or RO water?

soiless mixtures can easily hold in salts, you need to flush her out and stop feeding every other watering, soiless mixtures mostly have peat moss which hold nutrients in

flush her out good and wait around a week to feed and dont be using all those, its overkill

bloom and cal mag is what you need for now, but i would also be using earthjuice microblast in place of the cal mag, if you get some microblast put al mag aside

earthjuice microblast has all micros cannabis needs and plenty of it which would be used every 2 weeks or once a week at 1 tsp per gallon of water mixed in with your vegg or bloom fert

but flush your plant out realy good with lots of water

what size pot is your plant in?

if you have a 5 gallon size pot use around 8 to 10 gallons of water to flush her out extra good

but if your watetr is soft coming from a water softner that contributed to your problem because sodium is toxic to plants, they take it in before other nutrients and it locks out causing vascular damage in the plant which inhibits uptake of water and nutrients

you will need fresh water without sodium in it to flush it out well and good neough to start the recover process

on your last flush if you can add a very small amount of superthrive or B1 your plants will recover faster

but im talking about a drop or 2 in agallon of water

superthrive is very powerfull

not sure the dosage on B1 or thrive alive, it would say on the back though

Interesting you should mention the build up of salts. I was concerned about that about 2 weeks ago and gave all the ladies a flush with Clearex. Obviously that didn't work so well with this one.

I'm using tap water....80ppm before any additions. I'm concerned that the tap water I am using isn't so great. Initially I thought it would work out well because it has such a low PPM, but obviously its that way because of all the treatment. I dont treat the water myself at all....just comes out of the tap. I do let it sit so the chlorine will burn off. Do you think I should go with an RO filter and supplement the calcium/magnesium?

I have the ladies in 2 gallon pots and they will finish in them.

I cant thank you enough for the insight Stitch...I appreciate your time. I'll follow your recommendations and give an update in a week or so. Thanks again.

Doesn't sound like your tap water is a problem. There should be calcium and magnesium in some shape or form in your fertilizer program anyway.

Im kinda curious to figure whats in the mix thats pulling the ph up? The run off ph seems a little high for soiless.

 

[Jahminded]

I wonder if there is a way to remove the sodium from the water without use of an RO filter? I can definitely buy one, but I would want to be confident it would fix the issue.

The soilless mix I am using is Sushine #4. Great stuff....drains extremely well with plenty of air for the roots.

I was trying to be frugal with the nutes...I mean 800ppm is not excessive...there has to be something with the tap water....Stitch has me intrigued with the sodium angle. I just am not sure how to fix the issue. I have a feeling the other plants will soon show similar signs if I dont get this under control.

RO or some water treatment to remove sodium?

I really appreciate everyones input....thanks.

Ahh...look what I found....you gotta love the internet.....this is a water quality report for the city I live in...

Initially I was hesitant to post this for security reasons, but Sunnyvale is not a small city and I'm legal with Prop. 215 Medical Marijuana....

If anyone could take a look at let me know what they think I would appreciate it. Page 2 has a rundown of the water specifics.

Thanks again..

 

[Jahminded]

Anyone able to do a quick water analysis? Thanks.

 

[Verite]

Well theres some obvious numbers there that make me wonder. At least I think the reason the ph is going up is because the avg ph is 7.6.

The real perplexer is why you measure 80ppm outta the tap when the city measures the avg at 433ppm [TDS]?? Is your water treated inside your house? Does the sink tap measure different tds levels than the other taps in your house?

Other than that you got plenty of calcium in the water, natural sodium levels arent too bad. Plenty of boron, enough magnesium to get you close to flowering [ mj likes boosted levels of mag from about one week before flowering to about two weeks from harvest.] Not sure about the chromium.

Heres a pdf to show you all of whats good for plants at the element level.

Verite....thank you. That is really what I needed was someone in the know to take a look at the levels in my water.

Yeah I was wondering why my ppm readings were so much lower than the reported levels. I'm renting this house and I dont see any water softeners installed. I've checked the levels from each source...bathrooms, kitchen sink...etc..etc.. and they all read the same. Interesting thing I noticed was that the readings are about 80ppm right from the tap....if I let the water sit it raises to 100ppm. Perphaps that is just a calculation error because of the temperature change.

So TDS and PPM are the same? I thought there was a formula for converting between them. If not, then I have a missing link somewhere. Why is my water so much softer than the reported levels. I really need to figure this out because it will determine if I need CAL-Mag...etc..etc in addition to the plants normal ferts.

In terms of the PH level.....I've noticed it creeping up.....with the soilless mix I use I was keeping the PH at 6.0..Runoff is now around 6.4 which I am sure is contributing to some sort of lockout...I will start using the lower end of the spectrum at 5.8 and flush a bit more with each watering to see if that helps.

I also just purchased a Dechlorinator filter which takes out over 85% of the Chlorine in tap water. It was only $50 so I'm interested in seeing if that helps at all.

Verite...again....I thank you for your time and effort. I wish I could roll one up for you or buy ya a beer. If you make it to the 420 event in Amsterdam next year I will do both...last year was a blast...even though it was "unofficial".
