Not too worried about it, but it's really too early for yellowing.

Techaflora Recipe for Sucess; I Feed-Water-Water.

1 TBS Boost
1 TBS Grow
1/2 tea Thrive Alive RED
1/2 tea MagiCal
1 tea KoolBloom
1 TBS Black Strap Molasses.


Any ideas?

The other Swiss Cheese has no issues

[t looks like cal/mag def and possible nitrogen def.If she has stopped has stopped vert growth than start using your flower nutes.

Using FLOWER nutes. She's been feed FLOWER nutes now for 30 days. Should I add CaliMagic in the watering along with the Feed?

Her vertical growth has stopped @ two weeks ago.
 
Yes feed cal/mag along with your reg feed.Iwould still use some veg nutes at a reduced rate to see if that helps with your yellowing leaves.Unlees your using a lighter dose of flower nutes I would feed every other watering.
 
Hi Baylee- I think there's a couple things going on here,... looks like we have scattered spotting that smacks of Ca defc., and upper leaves that are yellowing, veins included in the more advanced symptoms, which hints at an immobile nute' defc.,... (LOL! -sorry Nammy, I think N defc. is out because of this,...)... Likely it's Fe, or less so, Sulphur (these two are so close in symptoms, it's hard to make a call with just a pic or two, but S defc. is rare),... muddying the water is the fact that leaves getting tapped out of all goodies also go overall-pale like this, including the veins, BUT usually, it's the lower leaves that get tapped first, not ones so high up,...which makes me think defc.; pH in is fine going in, but it's the actual soil pH that would tell us the most, especially for Fe, which starts to get locked out very fast when the soil pH starts getting into the upper 6's,... (that first pic show something very uncommon: veins going pale with interveinal spaces still green!- :dunno: that's diagnostic of something, but I'm not sure of what; almost always, the spaces in between go pale long before the veins color fades out) *** Okay, I dug around some more; looks like S defc. is more likely to cause the veins to pale-out than Fe defc.,... So to cover bases, treat for the Ca defc. with your Ca-Mg supp', and try some epsom salts (MgSO4) for the S defc. (1 level tsp/qt),... this far into budding, I hesistate to recommend foliar, even though this is the fastest way into the plant, and bypasses any potential soil pH issues-- (residues and mold issues).... *** as to why one of the same strain is fine, the other troubled,... pheno diff's can do this, and more likely, pH diff's in the soil... each pot is it's own micro-environment, and can drift a different way from another, despite near-identical treatments and conditions,...
 
What is the pH of your run off?
 
The last feed was 6.0 (IN) 6.4 (OUT)

So you're probably around 6.7 - 6.8. A little high but okay. Cal and mag are available in that range so I'd have to agree on the cal/mag deficiency. They are pretty common and it's not a bad idea to give them a teaspoon per gallon from week 5 on. I'd suggest giving them 2 teaspoons the next feed and then 1 teaspoon after that.

I always take Muddy's advise....consider it done.
