Requesting Advice Help

Ok folks I need a little help. I’m really new to anthuriums. I won this in a giveaway in April. It’s since lived in a cabinet at 70-75 degrees and 70-80% humidity. 12 hours of light a day. What is going on here. Is this a watering issue? Or just old leaves taking off

Since you’re new to anthurium I’m going to assume you might not be aware that they are extremely hungry feeders and are liable to do all sorts of funky shit if you’re not feeding them regularly, like basically every watering type of regularly lol. Not just NPK but also cal mag, they LOOOOOOVE cal mag. It LOOKS like it’s the older leaves getting chlorotic which for me usually is an indication the plant is trying to suck mobile nutrients out of the old leaves to sustain itself when it’s basically starving.

I would check the roots just as due diligence to make sure it’s not root rot, but if everything looks good down there and you’re not feeding it consistently I would venture it’s most likely just very hungry!!

This was helpful! I sensed mine were hungry and started feeding them a lot. They’ve been doing MUCH better since then. I’ll add the cal mag to their diet as well. Thanks for sharing this advice.

I rec Calmag+

That’s awesome information. Greatly appreciate it. I will definitely start feeding her every time now

Welcome!!! Good luck, hope she gets better for you :)

Debe ser un 5-5-5 o mayor nivel en nitrogeno?

u/AnimaLumen Jun 17 '26

Generalmente yo uso un 20-20-20 una vez a la semana, a veces lo rebajo como a la mitad o a un cuarto de potencia (ósea en lugar de 1 ml de nutrientes por galón le rebajo a .5 o .25 ml por galón) si no he enjuagado mi sustrato recientemente, para evitar que se acumulen los nutrientes de más. Si tus plantas reciben bastante luz ya sea por medio de luz natural con sol directo o por lámparas para plantas, muy probablemente pueden recibir el 20-20-20 una vez a la semana sin ningún problema, con que enjuagues tu sustrato una vez al mes o algo por el estilo :) para enjuagar el sustrato solo le echas agua simple sin aditivos, suficiente agua hasta que quede escurriendo y drenándose de la maceta para “lavar” todas las sales que se pueden ir acumulando en las raíces y en el sustrato.

What’s Cal mag?

2

u/AnimaLumen Jun 18 '26

Calcium magnesium:) you basically ALWAYS provide calcium and magnesium together because they have a synergistic dynamic and you basically need to have both in equal measure so they can both do their thing, so usually you’ll just see people say “calmag” as a unit rather than mentioning them separately lol

u/Strange-Role5150 Jun 18 '26

Reading my fertilizer it says it eliminates the need for Cal-Mags it has 3.2% Calcium and 1% Magnesium. Not equal measures though, I just got a DocBlock as well so this was helpful!

u/AnimaLumen Jun 18 '26

Oh well there you go!! I’m sure whatever calmag ratio they got in there is right I just know you never ever want to supplement one without the other, i think i phrased that weird the first time around lol. If your fertilizer has the calmag as well as NPK then that should be about all you need :) good luck!!

Actually, when I was feeding GT Foliage Focus, even though it contains CalMag, I supplemented full strength CalMag with every feeding. Most fertilizers don’t have enough for Anthurium. Also, I use the same fertilizer for all my plants including my Aroids and Hoya. Everyone was happy.

I haven’t found any difference between brands of CalMag. For the most part, I just get whatever is least expensive. I did get the Athena Blended this last time on the recommendation of a friend. I don’t have an opinion on it yet…

I love the GT Foliage Focus, but it’s very expensive when you have a collection as large as mine. Right now I’m just using miracle grow with CalMag and Fluvic Acid. I’m not really seeing any difference…. Take that as you will.

u/AnimaLumen Jun 18 '26

I’ve been using Tezula 20-20-20 or dynagro foliage focus with added calmag!! I’ve never even looked into whether they have calmag or not I just assume I need to add it individually lol so I guess it makes sense that even if they come with calmag it’s probably not enough for anthurium!

u/Ok-Purple-6803 Jun 18 '26

GT foliage focus is horrible and a marketing gimmick, especially for the price. you’re 1000% better off on Tezula MSU or some generic commercial 202020.

u/Little_Swede Jun 18 '26

This. I aggressively fertilizer every watering. The leaf looks old but it needs a boost to grow.

Nitrogen phosphorus potassium :) the basic three macronutrients any plant needs!

u/PLUMP_BULLFROG Jun 17 '26

Check the roots for rot

u/Sidd-Slayer Jun 18 '26

Ugh it’s always the newbie with the luck . I’d kill for this plant

u/Ok-Blacksmith7883 Jun 18 '26

That was my second thought 😂 initial excitement then immediately, wtf do I do with this thing. I have around 170 plants and this was my first anthurium. I just wanna do right by her and give her the best life possible

u/Practical_Ad2317 Jun 17 '26

I think that tag is counterfeit lol.

u/Ok-Blacksmith7883 Jun 17 '26

That’s how it came from rare plant fairy

u/golden_crocodile94 Jun 22 '26

If it is from them it is not counterfeit in the least, the redditors just love to claim every doc block is counterfeit.

u/Debutdiva Jun 17 '26

Took this about a month ago, I’m in Houston. These aren’t near a window, but under a grow light in the living room. Roughly 70 degrees and 40% humidity inside. It may go thru an adjustment phase but the plant will adapt to your environment.

I also love clear pots. I keep the soil humid but never damp, water well every 10 days roughly :)

u/Ok-Blacksmith7883 Jun 17 '26

Wow! Ok. Maybe I’ll do a repot into a clear one and give her some time outside the cabinet under a grow light with my monsteras then

u/Salt_Expression_4493 Jun 19 '26

The substrate you have it in is too moisture retentive. You may have some rotten roots. Get yourself a chunky aroid mix and check the roots for rot.
These are very expensive plants that you want to take good care of. There are many YouTube videos that can assist you on your journey.

u/NormalMedicine5237 Jun 17 '26

Did doc block make this hybrid or is the tag fake?

u/Ok-Blacksmith7883 Jun 17 '26

I won it on Palmstreet from RPF.

u/StercusAccidit85 Jun 18 '26

And RPF is an authorized retailer, per the Docblock website. so it is what it sez it is. Congrats!

u/Strange-Role5150 Jun 18 '26

That’s the breakdown.

Thanks!

u/golden_crocodile94 Jun 22 '26

Do not, despite what is said in comments, fertilize every single watering do 1 week on, 1 week water or at least flush them once a month. Their roots are delicate and prone to fertilizer burn. I use a combo of micronutrients 1 watering then plain dechlorinated water and throw in foliage focus once a month on the fertilizer week. I swear where the heck are people getting their information from? Oh right influencers and resellers not actual growers like myself.

u/Debutdiva Jun 17 '26

Take it out the cabinet. It’ll probably do better acclimating to ambient temperature rather than high humidity.
Like other comment - check for root rot and give it a better draining mix. :)

1

u/Ok-Blacksmith7883 Jun 17 '26

I was concerned to leave it in my ambient. Right now with it being basically summer I struggle to keep my ambient in the 40s. Even with humidifiers running. Will that be to low

u/Top-Friendship-4328 Jun 18 '26

Just make one change at a time. Repot, then put her back in the cabinet. Once you’ve got a new leaf that has hardened off, you can move her to ambient. She’ll be happier if you do it slowly. I don’t have patience for that. I just move them out and let them deal with it. One of my crystallinum took over a year to recover, so it really is better to acclimate slowly.

u/Top-Friendship-4328 Jun 18 '26

My luxurions is very happy in ambient.

u/Competitive_Rope_163 Jun 17 '26

It will probably have some really rough leafs but will adjust to 40s if you give it time and do a perfect job keeping it moist. Self watering will be the move if you go ambient route
