Skittlez strain
Long veg cycle 100 days so far.
Ocean forest soil
Water Ph between 6.2 and 6.5
Soil Ph 6.8
Calmag 120ppm
Also has hyd lime ammendment

I continue to trim leaves and adjust Ph and calcium. Using neem in case is was rust mold.
Any ideas ?

I have 4 girls in the tent but only this one has this issue.

I see a cal/mag deficiency (the rust looking spots) and the color change says low temps to me.
Maybe a low ph as well but I'm not positive of that.

Definitely looks cal mag, what's your overall PPM, might be experiencing some lock out? If I vegged for 100 days in hydro I'd have a 7ft plant when flipping lol.

 

[DanielWesterfield]

All nutrients have been eaten up in your soil mate. Definitely by day 100.
You need amendments.

Thank you
I'll try increasing calmag.
There is a 30deg temp drop when lights go off ??
I don't mind the color change and slow growth tho

Is cal mag the only thing you're feeding them? As someone said above, if so they are hungry and need more than just cal mag, they are pretty light green as well and look like they want some nitrogen as well.

When I see rust spots on the leaves I spray them with WD40. Works great, the squeaking stopped almost immediately.

Humor alert, don’t try this at home.

Was giving them a light feeding of AIO Grow 2-1-3......100ppm
I backed off when the rust started.

I started autos at the same time as these. I kept these small by design until I had room. Overall ppm is 350-375

They are probably hungry for everything, I don't grow in soil but that seems low to me for a plant that size. I would think like 700PPM?

Looks like a combination of CalMag and nitrogen deficiencies to me

I run flora Nova it's easy to use great results my light runs hot anyway so fans keeps my temp around 80 85 right now at night 70 doing the 18 and 6 thing . But yeah calcium for sure and more nutes..

Do you usually let the water sit on the bottom like that when you water? If you have that much water on the bottom you watered too much, even if it reabsorbs in the same day the bottom of the pot will be moist for quite some time. The rest might be nute depravation related but this right here is a classic sign of overwatering;

Also the tips pointing downwards like that can only mean 3 things, underwatering (no because I can see the water on the bottom), N toxicity (could be if you were feeding them and it started then but if theyre N depraved it wont be the case) and overwatering. If its underwatering they go back to normal, if its overwatering they will go back to normal unless the overwatering goes for more than once, then they will keep that shape, and with N toxicity is irreversible aswell. The paleness could also be water related, are all your stems red or purple by any chance?

Your plants look hungry to me. I’m not familiar with what you’re feeding them but they’re going to need more than that. I use MegaCrop and like @smoker0420 mentioned, FloraNova is an awesome line too. I do have to agree with @Eledin that they look overwatered. Letting your soil dry out a bit between waterings will help get some better oxygen to your roots.

If you’re using a CalMag product like CAliMAGic, you should be administering around a teaspoon per gallon or 1ml / L.

100ppm is nothing, it probably started showing signs of hunger right when you started feeding it just by chance and you took that as the plant burning from nutes, but I dont think you can burn them with such a low dose and the tips and edges are not crispy like they would be if you had nute burn.
So you have 3 other girls, and all of them are okay so far without feeding or are you giving them 100ppm? I honestly dont meassure by PPM when feeding but I think up to 600-800 should be fine for early flower, maybe even more, someone who meassures ppm in soil can tell you.

I read plants and skip the ppm’s too.

I go with the flow too hahaha but I go organic so with all the buffering and stuff is pretty easy to read your plants once you know how. Dont mind me if I burn a couple of tips though . That said I understand why people do it for hydro and I would probably do it aswell.

I think you can push them all higher, can we get pics from the others?

If they ain’t a little burnt, you ain’t tryin’
