Deficient?

[Zenocide]

What is going on with this baby, It topped its self as a seedling and I've been LST'ing and FIM'ing.

Temps all normal, Soil PH in tolerance including run off.

I'm guessing the potting medium ran out of juice but what deficiency does this look like?

What is the medium ur using?, looks a touch dense to me... No visible airation/drainage...and a bottom tray.

Did the soil have any food added? If peat based did it have dolomite lime added?

Looks to me like it's just as you said out of gas.

because Cannabis requires so muck calcium, magnesium , nitrogen ,phosphorus and potassium with a balanced level to actually be able to absorb I would start either some sort of feed program or top dress on a light sprinkle of a complete feed.

If you have some Epson salts about the house that would quick fix some of your micro nutrient deficiencies till you acquire a proper feed.

Foliaring on some of the feed right before you feed the roots will encourage the plant to take them up faster. Add a small amount of straight water will buffer the roots against their first food too.

Good luck, and try to get peak health before flower or it will be much harder for the plant to resist pests and disease in the early flower set phase...

Thanks you for you quick reply, The medium is Jacks Magic with Seaweed extract peat based, I did mix some perlite in with it at 20/80 ratio, The soil you see on the top was a top dressing (from the local garden store) I added at the start of last week that has compacted down with watering.

The plate/tray at the bottom is what I catch the run off in and I never let the plant sit in any run off.

I gave the plant a feed of some 4-4-4 2 days ago that I had lying around probably not the best but will have to do for now, I do have some Epsom Salts I will add a table spoon full to some of this remaining pre mixed feed I have left (4lts) from the other day.

Hopefully it will get better soon!

If you have a small sprayer I would also highly recommend spraying a bit of the feed on the leaves with a few drops of dish soap to help it stick. It will bring more feed from the roots and let in minerals that might be locked out in the soil to get right in the leaf. Very effective and fast acting, I do a few a week even on healthy rooms and I find my leaves get thicker and softer and all my stems are bigger yet more flexible without snapping...

Good luck, your plant looks very nice other wise, so I know you've been babying her!

Thank you also, I added a couple of drops of dish soap to a spare mister and filled it with some feed and Epsom salts and treated all the leaves hopefully I've caught the deficiency in time but if worse come to worse I will have to give it a flush.

Magnesium. Rust spots and yellowing and dying of leaves from the bottom up. Epsom will fix that quickly. You caught it in plenty of time to recover.

Yep you are 100% correct a dose of Epsom salts in with a premix feed and misting of the leaves has perked her right up I can see unaffected leaves turning green again and the effected leaves have halted their ultimate demise.

Mmmmm magnesium foliar is a great patch to the system. However, with that said, Mg on the soil is often an invisible no no. Usually low Mg is due to the lack of Ca and P, not the lack of Mg. In fact, when Mg is high in the soil, it is often deficient in the plant. The reason is that Mg closes down a soil, makes it tight, hold water, hold salts, etc.. making for water logging, less air, anaerobic environment and general lack of roots.

99.9% of the grows are calcium deficient. If you see Mg deficiency, by all means apply Mg to the leaves, but think twice about dousing a soil.

Back in my Overgrow days years ago..... I played sick plants mentor....

SOme of your pics of spots show calcium def....... The way I learned that some spots are calcium def..... is that a darker ring will be around the spot.....

Some of your spots have that going on.....

 

[slownickel]

I agree whole heartedly. Everyone on this forum has a calcium problem. EVERYONE.

Plant is hungry at all. Ca is immobile and always, always affect first new growth. Rusty spots, blotchy necrotic with some yellowing thats K def. But plant just want to eat, new growth is yellow and all kind deficiency starts.

 

[slownickel]

Maim,

Calcium affects all growth. No roots, no K uptake. No roots, no Mg uptake. When Ca is low, everything is low.

Yes, when EXTREMELY Ca deficient, new growth is the easiest to point out.
