New Grower Super Skunk, help needed

[sturgex]

This is my second grow and I decided to run some nutes with watering this round. All has been going fine and my Super Skunk and Northern Lights have been growing like crazy, but today I came home to find the leaves of the Super Skunk with some issues. They were not like this this morning.

Last watering was Monday, about 1 liter with FloraNova Bloom at 3 tsp per gallon.



This doesn't seem to be happening on the lower leaves, just the ones that are about half way up and higher.

I'm thinking it's just too much fertilizer so I'm going to water clean tomorrow and maybe the next time as well to see if it clears up. Thoughts?

I will be back in a sec I am gathering more info. New laptop, so I have to re aquire information

 

[Eekman]

OKay those are some charts for youz guys and gals to stash away for later. Sorry bout the leaf chart, but you can google a bigger image I am sure.

Make sure it isn't pests or molds get in there with 40x loupe or magnifier glass, or a camera on the under side of the leaves.

It looks like calcium and or mag deficiency IMHO. but we would need to know more. PH of your medium? In and out would be nice, do you have a ph meter? It could actually be locking out those nutes that it needs.

get back to us and let us know

---------Edit----------
I forgot to add that the charts do give an idea that Mo is missing from your medium, which is Molybdenum.
I use a product called excelerite. or Azomite.

the chances of having any of the lesser known def.'s get slimmer with this in your soil.

With that being said, I doubt it is that Molybdenum. I have never heard of anyone having that deficiency before.

later

Thanks, Eekman. The condition is more stippling than yellowing, but maybe I just don't have my terminology right. Also kinda weird that the Northern Lights right next to it, which has the exact same set up and treatment, isn't showing any signs of this. But maybe that strain is more tolerant.

 

[Eekman]

Yeah that is probably strain dependent stuff like you say. So you have to adjust and get in there and see what it needs.

How about the PH and the Calcium and Magnesium levels? How's your temperatures and ventilation?

Check out the feed schedule. You most likely are overfeeding. 1.5 tsp per gallon is MAX recommended dosage. This plant is so small that it requires about .5 tsp per gallon.. Your PPM's are probably 2400 if you used 3 tsp.

If you did giver 3tsp you should probably flush with several gallons of ph neutral water.. Give her a few days then add correct amt of nutes.

Holy crap, guess I should have checked the website. That's not at all what it says on the bottle.

I'll continue to flush today and see how she does.

Thanks for the link!

The Northern Lights is starting to show the same symptoms today, I guess it just took a bit longer to hit.

Eek, temps usually stay in the upper 70s (F) in the room, and they're not in a box or tent so they get plenty of ventilation. Just bought a PH meter (HM Digital) haven't done the test yet. Figured I'd flush and see how it goes then follow with testing if things don't correct themselves.

Sturg'- ..when I first looked at the damage, I though thrips,... but it not, thankfully! (stippling is the right word bro', that's exactly what thrip damage looks like),.... the next pic showed clearer symptoms,... I think you have a Ca defc. going,... what makes me think that this is Ca defc., very often, the spotting and discoloring starts along those lateral veins, and that it's hitting mid to upper leaves.... the whitish color is atypical, as is the shape of them,.. usually, it's fine red-brown spots and necrotic patches,... could be a pH thing involved here too, which can alter the symptoms from the typical sometimes,... without a proper pH reading of the soil, I don't recommend flushing... it's stripping away Ca and other nute's, plus waterlogging the soil like that is a stress source itself, smothering the roots and gas exchange,...Do you have a Ca-Mg supplement? try a full dose of that to start with,.. Ca is poorly mobile within the plant, so results may take a few days,.... a foliar spray would be faster.. ask if you want to try this, as it needs to be done right to be effective... here's a link to run-off testing for soil pH... that said, I dislike this method of testing because it has several potential sources of measurement error inherent with it,... best thing to have is an Accurate 8 soil pH probe, which will measure soil pH directly at that spot!... no "estimating".... https://www.autoflower.org/index.php?threads/another-quickie-reference-for-run-off-testing-and-ph-estimation.41733/
.... feel free to post up at the Live Help Thread, or Infirmary... these are the best places to go for such issues!

Hey Waira, thanks for the through reply! I already flushed but only ran about a gallon and a half through each on Friday. They're both almost dry already.

I do have some Ca-Mg so I'll give that a try.

I've always heard the soil ph meters aren't very accurate, but I can definitely see how much room for error there would be using the runoff method. I'll pick up the soil meter you suggests so I'm doubly covered.

Thanks again for the help, everyone! This place is awesome.
