What the hell?

What the hell?

What the hell just happened?

Where's sproutco?

Oh my god. <panics>

no....really <panics more>

MUCH more calm now

Well I'm going to continue to document progress for the good of the community.

After 3 days, she looks like this:




Definitely you can see the green creeping back in! Now, the tops are still yellow as are the upper fans as of this am. I wonder what I should do. After panicing I researched one of my questions and found that hot water will help dissolve gypsum. I will try this at the next watering.
I'm still wondering about pruning most of the fans on the other phenos to max yields/light penetration.

4.5 weeks

4.5 weeks

Here we are now at 4.5 weeks. The yellowing leveled off but the upper flower fans are still yellowing and "v-ing" up a tad. With the lower bud sites and fans so green, wondering if its deficient with some more immobile elements.
Attempted a foliar application of 1/4tsp epsom per qt directly to fans (both sides) only. This had little effect after 48 hrs. The last shot is the rest of the cab with the skunkxrudy hybrids, progressing as usual, no matter what they are fed.

What's your PH of the nute solution and the runoff? Most micro problems are PH or nute lockout related...

 

[Guest]

No meter, stuck with strips, I'll check both over the next watering and flush.
Thanks for checkin it out. She is in an unusually small pot (8") as she was just a tester, now I'm sorry I didnt go bigger! Hooray for cuttings!!

 

[Guest]

Going to attempt to adjust a little more this evening.
Going to raise the Ca by adding CaCl at around 69ppm along with the usual feed of Jack's at 1/2tsp/gal and the 1/4tsp/gal epsom salts. I'll Ph this before feeding and also Ph the run off, and if things look dif when the cab gets opened tonite I'll post more pics.
Additionally I may try increasing the spray application of epsom to 1 TBSP/qt for the fan leaves.

Ph'd Solution prior to administering, around the middle sixes (shitty test strips, I need to get ones that go lower). Run-off much more acidic as it was bright yellow beyond the colormetric chart.

Here are some additional pics pre-CaCl/nutes application:

Some additional spotting:


But still frosting nicely:

Going to get better test equipment today for Ph. Also, I have been neglecting to show the rest of the cab in order to keep this thread documenting only the "sick" plant for educational purposes. However, as they are being fed the same thing, (minus the CaCl), it makes for an interesting comparison of the different phenos.

I feel the 1/2 tsp of Jacks could be upped to a full tsp in comparison of the old greenlight blossom booster I used feed (which had inappropriately low Potassium/N ratios). Next feed, the others will get that, and the Mango will get it tonite in flush fashion. Yellowing is really staying to just the kola fans. Some of the brown spotting I have noticed, I believe was from the last foliar application of the epsom during mid lighting period. Too bad I didnt read the post on lamp burn and when to spray, although I never had a problem foliar feeding at anytime with the other girls.lamp burn

 

[Guest]

Still having some trouble finding lower end pH strips, testers. Gonna have to bite the bullet and go digital.

Noticing some increased upward leaf curl around edges of fans. Any ideas? Hows my light distance (400wHPS):



Distance about 12":

Looks like a little heat/moisture stress...what are the temps, airflow and RH%?

 

[Guest]

Air temps at the canopy are around 82 degrees. There is a pc fan providing airflow across the bottom of lamp glass which is also aircooled by the cabinet ventilation. Havn't taken an RH. I'll place the unit inside to obtain. None of the others in the cab seem to mind the current conditions which have been constant over the last 3 grows. Will report back in the next few hours.

RH in the mid canopy is around 40% apx 6 hours into the dark cycle. This seems low however it has not been an issue with previous grows. I will update with a light cycle reading this evening.

I also purchased an inexpensive two probe redox pH and Fertility meter. Soil pH is around 6.5 for all planters, although I'm doubtful of the usefulness of the fertility reading which measures NPK in the form of low ideal or high. It is reading in the low range which is not indicative of the levels at which I'm feeding.

I have noticed that one of the Sativa hybrids is exhibiting stretch of individual calyx clusters on the dominant cola. (pics to follow later)

The mango with yellowing fans is showing some additional brown spotting as in the above photo yet buds still seem to continue to frost and are VERY fragrant.

just FYI...Those two probe shove in the dirt meters are junk.
Go back to using pH litmus paper...much more accurate than that ripoff toy meter.
or bite the bullet and get a real digital pH meter.

How far along are they into flowering right now ?
waiting for the additional pictures.

Hate to repeat - but it's that important.

those soil probe meters will read the same if you cooked the garden - they give you a false sense of security and make the garden vulnerable. I know a good digi meter isn't cheap,,, but for what it will teach you,,, you can't afford not to.

I say that because in a couple months - you won't hardly use the meter until you change your regiment.

eBay is a great source for digi meters and anything else you can think of.

 

[Guest]

HAHA yeah I figured it was shit. It was so cheap I thru it in the basket while picking up some more MG organic mix for my clones as they got started too early. They are in pint cups and about 8"s and screaming. I'm gonna have to top em' as I have a few weeks left for the flower cab.

I saw a koi pond digi meter for like 57 bucks, full range, looks solid and as it measures liquids it should be much more accurate.

(sorry I hate linking direclty)
Any input?

The dual probe piece I'm going to deliberately run some QC's on to see just who accurate it really is with pH just for fun. Hopefully I can show what a piece of crap they really are.

Oh, I'll put some pics up later we are approaching 6 weeks of flower.

 

[CaptJamesTKirk]

Your Koi pond Ph meter looks fine.

Do a search on eBay too - look for a good deal from an estalished seller - they have new and used available.

Whatever you do - make sure you get pH 4.0 and 7.0 calibration fluids - a good meter ain't worth squat if it's not calibrated.

Shine on!

I did a quick searck on eBAy -
http://cgi.ebay.com/Hanna-pHep4-Dig...2QQihZ007QQcategoryZ58191QQrdZ1QQcmdZViewItem

seller has 15 THOUSAND feedbacks, 100% positive - that's strong!.

a used one with a TDS meter - and fluids!
http://cgi.ebay.com/TDS-METER-PH-TE...1QQihZ006QQcategoryZ42291QQrdZ1QQcmdZViewItem

Swimming pool and aquarium stores should have resealable bottles of calibration fluid - those packets are good for a couple days - if your lucky. (or a big mess)

I wouldnt go near any used pH meters...no friggin way!

But I'd absolutely endorse the hanna pHep4 all day long.
It's an excellent meter and a much better meter (and deal) than that koi pond source you showed

 

[Verite]

I second that on the used ph meters. The probes are made with stuff [ electrodes ] that only is good for a period of time and stops working well after something like five years or so depending on how well its maintained. Kinda like a plasma tv.

That is why there is a PH and TDS meter set for about $35 - if they calibrate and repeat - they are accurate enough to improve the garden - and for that price - a couple harvests and you can afford new stuff.

For $35 - I'm tempted to get it and I don't need it.

 

[Guest]

Liked the hanna model and reasonable especially considering the electrodes can be replaced.

Didnt have time to snap more pics (sorry no eyecandy) but the mango is not getting excessivley worse in yellowing although that brown spotting on the fans as in the above photos is still progressing. Definitely going to also get a shot of the crazy bud fingers. This happened on the last grow too to some extent. Mom might be getting near replacement.

I transplanted all the mango clones and moms. Tried MG's "organic" potting mix this time...gotta say, vs the original I'm impressed with the quality thus far.
Pics WILL eventually follow
