Another Tabletop Crop: Carmen's Spring Grow With Vipar Spectra XS 1500 Pro

Highya Carmen,

I still think it's a cal/mag deficiency. I thought that the first time you showed us the leaves. I had it this year, using SIP planters. Only time I grow in pots. May limp through the next couple weeks to harvest.
Those buds/colas are gorgeous! Big buds overshadow deficiences, in my opinion. Looks really fine! Great job with the Chocodope and the Blueberry Auto.
I hate when we can't figure things out like that! But smoke a bowl and relax!! Happy Smokin'

Wouldn't that be a thing hey, if it is a calmag deficiency. I have been careful to avoid calmag, so it is not out of the realms of the possible. I'm going to think on this some more. Thank you Bode. I hope you are having an awesome start to Monday :passitleft:

Hey Chomsa. As many others have said, I wouldn't worry about it now. I think you have enough green to get you through. Those buds don't look like they are taking strain either. Have a happy day

Thank you :) Hopefully I can get the two new ones through to the finish without blemish. Have a lekker evening.

Public service announcement:

Anyone who wants to test their soil pH using the runoff should follow the scientifically proven "pour thru method" outlined here in a pdf from Cornell University.

Testing your runoff any other way is as accurate as calibrating your pH meter using tarot cards. Oh yeah, use a calibrated pH meter if you test.

For those who don't trust pdf files, here are the instructions:

Steps for the PourThru method
1. water containers to saturation (so that a few drops of water come out of the
bottom of the container) with the normal irrigation water they have been receiving
2. after container has drained for one hour, place a saucer under the container
3. pour enough distilled water on the surface of the container to get 50 mL (1.5
fluid ounces) of leachate to come out of the bottom of the container
4. collect leachate for pH testing
5. calibrate pH meter
6. measure pH of samples

Thank you for pointing out the correct way of measuring runoff to determine soil pH.

Question. When I do my runoff tests I use RO rather than distilled. Is that ok or have I been doing it wrong and should I specifically use distilled water?

You have plenty of nutrients in the medium and most nutrient deficiencies are pH related with plenty of nutrients and complete plant foods. You're in mid to late flower so my guess is your pH is getting on the lower side? Do you keep track and measure pH of your runoff water?

Could it be that some of the deficiencies are related to input ratios in the media antagonizing others as far as availability?

As I recall the only replacement for distilled in pH tests is deionized water but I won't swear to that, nor do I know where you'd get it. Not sure where you are but distilled water is really cheap here.

From what I know both distilled and RO generally have the same pH(7.0) and are demineralized. The only difference is in how they are derived. If I'm using it for testing soil pH the only real thing that should matter is the pH of the control water since both have been demineralized.

Given how cheap distilled water is, why make that assumption? I have never seen RO water mentioned in any of my pH test research (and I've had to do more than I ever wanted to), so run it with distilled would be my recommendation. We don't usually try to cheap-out on our grows so why start with something that costs $1.25/gallon.

That's not a very practical way to use runoff as a measure to dial in pH. You should ideally use runoff to spot pH drift and get a curve on how things are moving and changing throughout the grow. When you've run a couple of cycles of the same strain you get a good recipe and blueprint for growth and a good idea on how to compensate for pH fluctuations.

It's not a good idea to flush the medium with distilled or RH water to take a scientific point of reference, that's not what we should use the runoff for IMO. You will only cause pH fluctuations in containers because there's nothing to buffer the solution going in the medium. Other possible issues from flushing the medium are nutrient deficiencies.

If you're taking that approach I think the traditional slurry test is a better and less "invasive" approach to take a pH reading of the medium without having a proper soil pH meter.

Excellent points. I've used the slurry test method also. Looks like that's what I'll be doing if I do periodic checks.

If I run into any deficiency issues then I'll run the distilled water process.

Also to be done with distilled water. Just go get a gallon so I can stop talking about it! :)

Simply a little happier after looking at all those flowers, Carmen.

Those flowers are really stacking well! If my autos can be like that I will be 100% happy. :)
 
Highya Carmen,

Love looking at those colas! Gorgeous looking buds with all that frost! Very nice work, Carmen! Happy Smokin

P.S. The malady in the leaves didn't look so bad. Is it getting better?

I think it is still progressing but it's a fairly slow progression. It is affecting leaves that were previously unaffected. I think it is different to a calmag deficiency. The discoloration is on the very margins of the leaves and usually with calmag the leaf tissue goes a blueish color before it browns off. This looks more like a Potassium issue to my eyes. I think that the root soak idea would be good practice, but I don't have the physical strength to lift the plant when it is soaking, so it isn't going to happen, unfortunately. I could do a proper flush but I hate to do that. It shocks the plant in my experience. My thinking with this plant is that as long as there is enough green in the leaves to carry it the next three to four weeks to harvest, the plant should be ok, fingers crossed.
 
Is this plant ready for harvest? It stopped drinking a few days ago. The trichomes are too small to photograph with my camera lens and I have not mastered how to use a loupe. I am not seeing any amber trichomes but they look mostly cloudy to my eyes.
