****Name That Deficiency!!!!***

[Cann-i-grow]

Indoor grow using Roots Organic soil. Week 3 of Veg. Temp 72-79 RH 40-60%. Using Dr. Earths Organic compost and making tea. Nutes every week at 100% now. Using water straight from the well with a ph of 6.8 (sent sample of well water to be tested, should be here tomorrow).

After some research, here's what is being suggested:
• Nitrogen deficiency
• Nitrogen deficiency due to calcium lockout
• Zinc deficiency
• Iron deficiency due to pH imbalances making iron insoluble

Not all of the plants are like this but maybe 6 out of 29

Please let me know your thoughts, diagnosis, solutions, etc.

Thanks for your time!

Nitrogen usually starts bottom up. Maybe always starts bottom up? I don't think it's nitrogen. Probably Zinc or Iron.

I have a different list.....

zink

magnesium....

I dont think any of the others make much sense.... the leaves would be green on the tips light interior for iron....

 

[HighAndHappy]

Mg

Zinc Deficiencies:
Deficiencies appear as chlorosis in the inter-veinal areas of new leaves producing a banding appearance. This may be accompany reduction of leaf size and a shortening between internodes. Leaf margins are often distorted or wrinkled. Branch terminals of fruit will die back in severe cases.

In this case Im suspicious of the upper leaf sizes

I guess a pic of the bottom of the plant would help...cause you can't really tell what's going on down there. But ya its probably not Iron. I think most likely its Zinc.

Hey guys thanks for the input. Still waiting on the water test. And lights out for the night so I cant take a photo of the bottom until tom.
Looks like Dr. Earth is more of a balanced fertilizer and has a higher P count then needed in veg. I may be locking out other nutes with too much P. I flushed today and will wait to see what that does. I figure that will take care of nute locking as well as the possibility of over fertilizing. I also prefer not to just add things which could make it worse and ruin my chances of really figuring out the problem by adding more variables. SoI'll keep this updated with a new photo tom and the results from the water test and hopefully with all your help we can figure it out. Thanks again for the feedback.

Cheers.

are the lower leafs twisting? it's hard to tell from the pic. if so my guess is manganese. if you have a (MN) deficiency it's most likely you have a zinc deficiencies too.

foliar feed with a water soluble micro nutrient with mn chelate

next time you start a grow use some greensand that helps prevent MN and zinc deficiencies

good luck!

I have forgotten worse things ..like 2 years in Daytona beach...my ex reminded me how old I was on my birthday,,,,,,lol....yeehaw

Thanks for the help Mystic Funk. Yes the leaves twist a little at the bottom. So we have diagnosed the deficiency, now to find the cause. Is it due to the fact that I dont have enough mg/zinc in my current nutes or is it an excess of something else locking out the plant from taking in mg/zinc?

I have flushed and its been 2 days. I have not yet seen them recover. Should I do a 25% nute feeding with the mg chelate in addition? OR just a foliar feed of mg chelate?

Also, I use a super soil that cooks for 6-10 weeks. Will the greensand be added before or after the cooking process? And what does the greensand exactly do to prevent the mg and zinc deficiencies? (just so I fully understand)

Thanks again.

What nutes are you using at 100%?

 

[Cann-i-grow]

What nutes are you using at 100%?

I'm using Dr. Earth Organic: Natural Wonder. Making a compost tea and nuting every week. Feed, water, water.

AWESOME! Flowcharts are the best.

sorry i'm a little late.
hope they're doing ok?

yes add the green sand when you build your soil mix to help release the manganese. green sand is to prevent manganese deficiencies it's too late to add it now because it takes some time to break down.

manganese deficiencies are rare. the first thing I would look into is PH of your soil mix. do a soil PH test not a run off test.

take 1 cup of soil from half way down the pot and add it to 2 cups PURE water. less then 100ppm with a neutral PH of 7. them shake well for a couple minutes let the dirt settle to the bottom of the jar. then take some of that water out and PH test that. your PH should be around 6 to 7ph. I like mine at 6.5ph.
