Are these chlorosis? If they are, what type?
#Monstera
The bleached effect on the 1st photo appears only on new leaves and decreases as the leaves get older but the leaves still look different than the much older, original leaves.

The mottling in the 2nd photo is rather new. I've noticed a few splotches here and there before but this is the first time I see it on almost the entire leaf. Again, this is a new leaf - 2nd newest. The newest leaf (still unfurling) doesn't seem to have it.

I've also just noticed the yellowing/bleaching on the lower tips of some leaves (3rd photo). These are the medium leaves.

I've checked for pests and there aren't any. Grow lights give them about 500-700fc for 12 hours daily. I've also read several journal articles for mineral deficiencies but nothing seems to match.

The plant has doubled its height and some more since I got it (the plant card shows the original height when I just bought it in May). New leaves appear so quickly one after another but they don't get big anymore.

1st and 2nd pic. This looks quite a bit like interveinal chlorosis to me, and since it is on new growth I would say its an iron deficiency. You could try repotting as the the new soil might have some minerals in there for the plant. A low strength fertilizer could also help this plant out, just make sure the fertilizer includes Iron (Fe) and other micronutrients.

3rd pic. Improper watering, both under-watering and overwatering, can lead to issues with Monstera plant leaves turning yellow. If the leaves feel dry and brittle, then they are likely dying due to underwatering.
Dang, Orked! You know what you're talkin about! You have definitely done your research. I think you should know @ForFoxSake - y'all both know a lot about plants on a whole different level!

When I look at the leaves of your plant, it reminds me of my Adansonii wide form when it was getting too much light.

The leaves would start out getting small spots on them and them eventually the whole leaf would either recover ir go completely yellow.

Once I moved it back from the light, it really settled into growing great, green, beautiful leaves!

I wonder if decreasing the amount of light will help. I'm sure @ForFoxSake can help, too.

Now, if you'll excuse me, I have to go look up "chlorlsis".
I forgot my pictures. (:
@KikiGoldblatt now that u mention repotting, I actually had repotted it in late June and I did cut back the soil portion in the potting mix because I thought I wanted to experiment with the new recipe. Now I feel silly for forgetting that 🀣🀣🀣. I don't think I'd repot again for the rest of this year so I'm gonna try to reassess the fertilizer situation.

The texture of this plant puzzles me. They are neither crispy dry nor waterlogged. If I could compare it with another material, it'd be like taffeta. Is that how it should be? The yellow parts don't feel any different than the green parts (maybe not yet). But I do have another question in relation to watering. I use a transparent (but frosted) plastic pot for this plant and I water only when I see (through the pot wall) that there is no water vapor left. Am I doing it right or am I actually depriving my plant?
@sarahsalith oh you're too nice with your compliments, but thank you! Unlike @ForFoxSake, my knowledge doesn't really translate in my plant care practice because I'm always struggling with my babies so I really do appreciate all the help that I could get! 🀭

I've seen your photos and I could see the same streaks? on the lower leaves of mine. Speaking of lighting, I also think that I've been giving mine too much light because the problematic leaves do get more light than the ones at the base (where it's more dappled and shaded) BUT my lighting is only 20% than that of in the nursery so that makes me doubt the overexposure theory. How quick did it take for yours to recover after you move it back from the light?
@Orked I could tell within a few months that the leaves stopped yellowing.
@sarahsalith I thought you were going to say weeks πŸ₯²! Months is a long time for me but I'd sacrifice my impatience for this plant 🀭. Thanks so much for your replies! You and @KikiGoldblatt have been super helpful in troubleshooting this problematic plant of mine and I think Greg should allow more than 1 best answer.
Plants can go downhill pretty fast, but they take a long time to recover. The sun can burn a plant and it can look really bad the next day, however, it can take months to recover.

A bad example is like breaking a bone: the break happens immediately, but it takes a while for it to heal. οΏΌ

I know it's hard to wait, but I like think of house plants more like bonsais (a labor of love that can sometimes take years to cultivate but I can pass on to someone else) οΏΌand less like something plastic.

Plants sure do teach me patience and understanding. πŸ˜‰
I like to add a small bit of chelated iron to the soil. Make sure to check ideal pH for the plant as the more iron the more acidic the soil.
But... If you need a more acidic soil chelated iron is really fantastic.
@sarahsalith that bonsai analogy makes me see houseplants in a different light. I think I struggle a lot because I'm too afraid to try and always reluctant to wait and that will have to change. Instead of stressing over the challenges, I should enjoy them as part of learning. At least if the plant dies before its time from the trials and errors, I can always try again with a new plant and better knowledge rather than restarting with the same uncertainties. Thanks! 😘
@ZarfHope the ideal pH would be 5.5-7 and now I'm at 7ish. So yes I still have room for a little more acidity. Thank you!!!
@Orked ABSOLUTELY! Do you have how many plants I've killed? I sure as heck don't. πŸ˜‰

This is a wonderful journey of finding out what works for you. (:

For instance, it took me a WHILE to get the courage to cut a plant back- now I do it all the time! I know that with most of my plants, when I cut a stem, it will BRANCH! (Usually with the thicker stems or branches.)

I chopped up my HUGE Monstera because of reasons and now it's AMAZING! It's going to be a whole MESS of plant by next spring! Five thick stems have two or THREE new growth points which will all end up being new stems with new sets of leaves! I'm going to have to think about how I'm going to care for this beast and I'm so excited!

Plants are usually very forgiving over time ... and it helps to have a whole bunch of people who have been there and done that. (:
@sarahsalith wow that's amazing! This monstera adansonii of mine is grown from 1 single vine and instead of chopping it and making the plant bushy, I keep it long because I'm afraid I'd kill it 🀭 i really do wanna pop that fear bubble so I'm gonna take a small cutting and then proceed to other possible treatments. How exciting!
@orked what kind of water are you using?
@angelw1975 i use ground water but it doesn't leave lime scale on the leaves except occasionally so I guess it's not too hard. Why do u ask?
@orked thought maybe your water could be high or low in some chemicals/minerals as well. A foilar spray feeding could speed up the green...for us impatient plant people!
@angelw1975 I've never tested the water composition so yes i do agree with u on the possibility of mineral imbalance. As pointed out by @KikiGoldblatt, I'm gonna say it's lacking in iron (among other elements). I might consider foliar feeding because I think I already have it somewhere in my supplies but I'm gonna need to read more on chelated iron as @ZarfHope mentioned and see if I should use only one of these methods or if I could combine both. Thanks for ur insight!
