What deficiency is this? (PICS)

[Ms.NatureFaerie]

Help! I need help diagnosing what is going on with these plants.

Possibly Needed Information:

Soil: FoxFarm Ocean Forest Potting Soil
Soil pH: Looks like around 7.0

• Test can be seen in the last pic

Water: Tap

• switching to distilled from here on out

Nutrients: Tiger Bloom, Grow Big, Big Bloom

• I have only used very small doses of big bloom and grow big so far in two feedings

This post disturbs me. That's like having a heart doctor say "yep...it looks like you're gonna die...but I really don't know yet..."

I'm watching this post though, cause I've had some leaves that look like that in the past with this plant. I thought it was from the slugs so I trimmed them off as best I could.

Yikes, that is a nasty looking problem. Can you run a PH test of your Fert solution and let us know the results?

Also, since you have the testing kit can you run a test on your Nitrogen, Phospherous, and Potassium levels in the soil, and let us know the results?

Are you adding Grow Big, Tiger Bloom, and Big Bloom all at the same time? If so, you should only use Grow Big during Veg, and Tiger Bloom during Flower. Big Bloom can be used during both veg and flower. Mixing all 3 at the same time can be toxic.

This should be a good start to try to figure out what is going on.

I am not adding the three together so that is definitely out. Do you mean test my water with nutes included or without? Is that how I test the Nitrogen, Phosphorous, and Potassium levels? Thanks for your help so far!

*edit: nevermind it has instructions for testing the Nitrogen, etc. I will test this and post back sometime tomorrow.

Glad to hear that you're not using all 3 ferts at the same time, so you're right, that is out as a possible problem.

To PH test your Fert solution, yes, you want to test the combination of water and ferts. I assume you probably have a gallon jug of water or something like that, and you have been adding ferts to it. Hopefully you have some sort of a PH test meter or even better, a liquid PH test kit.

All of the test results should provide a clearer picture of what is going on.

there is a pH lockout of nutes. Probably a few. pH test your runoff water and then adjust your watering water ( h20 + nutes) to have a pH of the runoff at about 6.5

Excellent pictures, that is the way to get some fast help, provided someone can diagnose your problem, lol


So here's what I see, and what I would do.


The PH level of your Fert solution looks perfect


The Potash looks to be within range


The Nitrogen looks to be very heavy


The Phosperous looks to be within range


My initial thoughts when looking at your pictures was a severe Calcium/Magnesium deficiency. The problem is the issue on some of your leaves is much too aggresive. In otherwords I have seen bad Calcium/Magnesium deficiencies, but the leaves of your plant were off the scale.


This leads us back the other way. Instead of a deficiency, you may have a toxic situation where your PH is perfectly in line, but because of that, all nutes are highly available. Based on the great pictures you posted, it is my opinion that your plants have a Nitrogen toxicity. The leaves are displaying all of the signs that they are getting burned from the inside out.


I would recommend that you flush your soil with 3 times the amount of water to soil, in an attempt to try to get to some level of stability. For instance, if your plant is in a 1 gallon pot, flush it with 3 gallons of PH correct water. Make sure you PH test the water before adding it to the soil, you don't want to compund the problem. The PH level should be right around 6.8 for soil.


Something else you can do in the meantime, this may seem useless but it could help. Get a bottle of PH correct plain water, and mist the leaves on your plant 3 times a day. If the leaves are in fact being radically burned, the plain water may help in slowing down the burn rate.


The bottom line is you are dealing with a potentially unknown problem. The easiest way is to get back to sqare one by flusing the plant and trying to stabilize it. There is no question your plant has a significant problem, if you do nothing, the problem will undoubtedly become worse. On the other hand you may be able to save the plant by taking some sort of defensive but neutral action.


Sorry this response is so long winded, but I'm very intrgued by the issue.

Please keep us posted and let us know what you find.

[Ms.NatureFaerie]

Thanks for your help once again

When you say flush you mean for me to run 3x pot size all at once? I have 5 gallon pots so that's a lot of water lol...but I will do it. Just waiting on your response so I know for sure how to flush.

[schmedrickk]

Hi,

Yes, when I say flush, I mean water your plant. 5 gallon containers are indeed large but you did the right thing if you are intending on growing some monster plants

So yes, if your plants are in 5 gallon containers of soil, you will want to water them (flush) with 15 gallons of water. I agree, that is a lot of water, lol

Regardless of what the problem is, flushing will almost always take your plant back to a neutral state. Then you can get your bearings and slowly back into ferts, and you should be OK. I should mention that after you flush your plants, you won't see the effects immediately. It will take about 5 - 7 days before you start to see a stabilization.

I'd really like to see those puppy's when they are fully mature in 5 gallon pots

[dijobo1]

I am anxiuosly awaiting the out come of this also. You're situation can really help others. I hope for the best for you and the pups. I will be following this also.

[Ms.NatureFaerie]

Flush complete...that was fucking tiring lol. I guess time will tell now. I will report back once it has been about a week to let everyone know what's going on. Thanks!

[schmedrickk]

Excellent, I know what you mean, I had to flush 2 gallon pots and that was a serious pain in the neck.

If you have a spray bottle, it certainly would not hurt to mist the leaves of your plant with PH correct plain water. As a foliar feeding, that should help to slow down the burn rate.

Within 5 - 7 days you will want to take a very close look at the medium to newer growth on the plant. If our calculations are correct you should not see any spreading of the problem. The leaves that have already been damaged will more than likely not recover, because the damage to the cellular structure of the leaves is too extensive.

You might want to consider taking a pair of very sharp shears or scissors, and clipping off the damaged leaves about 1/4" - 1/2" from the stalk. You don't want to clip the leaves too close to the stalk or it could restrict the flow of the nutrients to any branches that may be growing just above the damaged leaves.

Looking forward to your report in about a week.

[schmedrickk]

Oh, I meant to ask. Since you have successfully flushed your plant, can you run another Nitrogen test on the soil? I'm hoping the results won't be very purple like they were the first time around.

Thanks!
