Grand Daddy Black Grows A Stack

[Grand Daddy Black]

Hello growers.

It's Flip + 40 for the Clones.

To date, the Kera clone has been problem-free, but no longer. She is showing leaf discoloration that seems to be related to a nutrient deficiency. I'm still working on my diagnostic skills so I'm not sure what the leaves are showing me. I'm guessing the increase in potash released by the Dots at this stage may be screwing with the manganese and/or iron levels. If that's the case then all roads lead to a need for calcium.

Then there's a side of me that wonders why only one of the three Dot-fed plants would do this. Why not all three?

So I've prepared a slurry mix of her soil that I'll be measuring in a few hours.

If the soil PH is okay I will mix a special feed for her that contains organic calmag @ 10ml per gallon.

If anyone thinks this is a bad move, please do not hesitate to say so! I'm not easily offended.

This is the kind of stuff I hoped to avoid by using the Dots. Alas, it is not to be.

Thanks for looking in.

Peace.

Maybe this is the exception that proves the rule!

Hello again gang.

I did the slurry test of the soil of the ailing Kera clone. It's at 6.2 so no issue.

Now I'm back to thinking about why this is happening to only 1 of 3 of the Dotted plants. Rather than prep a special calmag blend for the Kera alone maybe I should just give that same feed to all three, like kind of a preemptive strike for the other 2 plants in case they're heading toward the same condition.

This grow is straying from the relaxing, thought-free grow the old Benz Diesel (my brain) was hoping for!

Try looking up phosphorus def? I'm not perfect at this but it looks it to me.

I doubt it's iron or the whole leaves would be pale and manganese deficiency would show black dead spots. An excess of potassium would show as leaves burning at the edges rather than yellowing like yours.

Are the stems newly purple? That would make it a phosphorus deficiency as Otter mentioned. It's possible that that plant in flower has a higher need for P than the others.

This is why I'm hesitant to offer my diagnosis. I'm always wrong!

I usually look and my leaf deficiency chart, where all the pics look about the same to me. Then I scratch my bald spot for a while and go to the Mulder's Chart, where all the lines seem to indicate Calcium is the key to any problem. Then I scratch my bald spot some more before announcing to myself, "I've got it!" But usually I ain't got it.

Thanks for you input gents.

I'm not going to fret about the Kera just yet. My short-term memory kicked in and I recalled that a short while back the other 2 Dot-fed plants did the same yellowing thing as a result (probably) of the nitrogen diminishing in the feed. At the time I noted that the Kera remained completely green. So now I'm thinking she's just now reacting to the N reduction, just a little later than the others.

So I'll just sit tight and see what happens next.

Here are the girls this morning:

And here is the MC-fed Black Domina clone. I dropped her MC down to 4.g (from 5.5) and added 1g of Calmag Pro(8-0-0) in an attempt to address her yellowing.

Thanks for looking in.

Peace.

Sounds like me.

Very interesting and informative thread you have here, one could say you could likely start at the beginning and witness the progression of our mastery until the present. When do you expect that there will be a change, and do you think those leaves will recover or are you simply trying to stop the spread of said deficiency? It's been a long minute since I dabbled in soil so my memories fuzzy.

Hello Addo. Thanks for your interest and kind words.

I expect (hope) that the yellowing will not spread much more -- that this is just a temporary adjustment to the way the nutrients are formulated to time release and have now dropped the Nitrogen down to a low level.

Those leaves will not recover. They will eventually die and fall off or get plucked off.

Hello growers.

I looked in the tent this morning to see some long branches flopping down towards the floor. The two largest plants (the Kera Bgum and the trained Black Cherry clones) were badly in need of some support.

I put some bungees on their pots and inserted bamboo sticks, then proceeded to tie some of the floppers to the sticks. And since I had them out, I took some solo pics.

All are on Flip + 43.

untrained Black Cherry Pie clone:
This one is low maintenance and kind of interesting to watch. I've never let one grow naturally before!

Trained Black Cherry Pie clone:
She's doing well, just flopping!

Kera Bubblegum clone:
The tallest one was really hangdog. I had to tie her in about 5 different spots. The yellowing of her leaves has abated through no action on my part. Seems that the yellowing was just a reaction to diminished Nitrogen in the feed.

Black Domina clone:
I'm still trying to get rid of the yellowing on this MC-fed one, but she's not cooperating.

Tent Pic:

That's a wrap.

Thanks for looking in.

Peace.

Great looking buds on everything, GDB. I'm doing a natural short veg grow now. They fill out nicely.

Thanks Stinker.

I see they fill out nicely!

Sorry I missed this from the get-go. I'm going to go back and play catch-up!

The untrained Black Cherry Pie clone looks nice but the Trained Black Cherry Pie clone is truly spearalicious!

Love the spiral staircase on the Kera clone and great news on the yellowing taking care of itself. Noted for next time so you can worry less if you see it again.

I'm still trying to get rid of the yellowing on this MC-fed one

You and everyone else on MC in later flower. Unless you have a source that's only nitrogen I wouldn't chase the fix.

What do you mean, just feed her Nitrogen and nothing else?

 

[InTheShed]

If you had a source of N only, yes. Or maybe some magnesium nitrate (since MC could use a bit more Mg). Most N sources are cal-mag, and MC doesn't need any more Ca.

I have some magnesium nitrate. What dosage would you recommend at this stage?

Is your MC the 9-6-17? What are you feeding it now?

I'm feeding at 4g per gallon.

That's all? Are you adding supplements?
