Any idea what's wrong here?

I'm having a problem with a few plants, what does this look like to you? They're currently under a 600 watt mh which is raised up pretty high, temps are between 73 and 79, humidity is around 50 and up to 80 at times, watering with declorinated oxygen enriched tap water, medium is a soil mix with a little bone/blood meal, humates, mycoriaza, tiny bit of sheep/cow manure, bat guano, perlite, they're watered a little with seaweed/fish guts tea (lightly once in a while).

The leaves feel flimsy on these ones, not exactly crispy but dry. I do have other plants in the tent (not weed) and had issues with a few damping off.

Could the soil be too rich? That's what i'm leaning towards but am not sure, it's only a few of the plants. I'm just worried it's something that can spread so i put these ones away from the others but still in the tent.

Any suggestions are appreciated.

btw my ph is 7, just misted them with b1/yucca in case it's a disease.

the droopy leaves look like overwatering. the yellowing on the bottom and those spots look like nutrient or micro nutrien deficiency. good luck

Thanks, could quite possible be over watering but they have plenty of nutrients, I was thinking it was maybe too much. Guess I could folior feed them and see if that helps or makes them worse. Thanks again

papary leaves, slow growth, slightly pale foliage, yellowing and leaf necrosis?

Diagnosis: humidty and heat too high, leafs cant breathe.


Ventilation.

you can have all the nutres in the world, but if the leaves cant move air in and out, they cant do shit. get some air in their, drop your humidity to ~50% to 60% max, and get your temps down to ~70ish

over watering for sure, and possible light burn on those lowers. did you spray under the lights about a week or two ago?
dont feed them anything for 2 weeks. that soil looks rich.

The damping off tells me that you're environment is too wet.

In my experience, those cups are bad for plants. They tend to bottleneck water at the bottom, the soil stays waterlogged and the roots suffocate. Looks like a couple issues which are probably a result of soggy soil. I would repot them, water to ensure even moisture then let them dry out evenly. While you may not be watering frequently, you still are overwatering because the soil never dries out.


I don't like humidity over 50%. Too many potential problems with no real benefit.

Thanks for all the info and i agree with all of it, it's too humid and i have been overwatering, also do mist them often but the lights are off then the humidity gets ridiculous. I'm going to repot these ones and go easier on the half drunk over watering in the middle of the night lol, i should have known better. Thanks fellas.

my growroom is between 78 and 85 sometimes and my plants are fine and get plenty of air, do you have an exhaust system? i think the temp is fine, my humidity is low tho, highest it goes it like 30% its in a basement as well.


those spots on the one plant is most def a nutrient or micro nutrient deficency. keep RH down. good luck

Thanks man.

Stop misting as well.

Here's how to solve your problem. Spend some money and get black plastic pots with holes at the bottom for good drainage. I reccommend Sunshine Mix #4 it's a great soiless mix and has good aeration. You need to let your pots dry out pretty well before you water again. I water every 2 days. Stick you finger into the soil, if it's wet DO NOT WATER. Wait until you stick your entire finger in there and it feels bone dry, then you can water. A good way is the finger test and actually lifting the plant up, if you lift it up and almost hit yourself in the face because it weighs nothing then you can water Don't be afraid to let your pots dry out, they will thank you with amazing growth and the leaves will be pointing straight up like they are praying. a PH of 7 is too high. 6.5 for soil mixes is perfect. Just follow the basics, good aeration, good drainage, stable temps and great airflow. Humidity should be 50% MAX. 40% is better. When I say I water every 2 days that is for my flowering plants that are 2.5-3 feet tall and growing fast and producing big buds. You may not have to water for an entire week depending on your situation.

this is also what i do, every morning/day i go in my room the first thing i do is pick up all my plants, i can tell by their weight if its time to water or not, place a few holes in the bottom jut to be sure nothing is just chilling downthere, like dude above me said, stick your finger in the soil like 2 or 3 inches, it should be dry or at least mostly dry with a small amount of moist and then you can water.


Put is this way, its much much easier to over water cannabis and all plants in general than it is to under water them, and when they are underwatered, you will know immediatley they do not like it and will droop badly letting you know.

If I were you i would drill holes in the bottom if you havent already and stick a fan in there maybe when the light is on to try and dry it up in there, I wouldnt even go near those pots with any water at all, you might not have to water for 4 or 5 days if its wet enough. My plants are about 3 to 3 and a half ft tall, 3-4 week flower very nice size buds in 5 gallon pots, i have to water pretty much every 24 hours, if I give a good watering more than avg. than I can get away with 36hrs-2days without watering, but after that eh, its anyones guess, you will get a feel for it as time goes on, dont worry. Like I said, i made it a habit to open my tent everyday or whenever maintence work was to be done and the very first thing that i did was lift plants and stick my finger in the soil, I dont need ph meters, i dont need ppm meters even anymore, I have both, but rarley use them, basically once in a great while ill have a small def. or small over nute and only then will I inquire about my ph and ppm (EC) levels. Now, im not recomending you do this as like I said, I have been at this for a decade or two lol. I used metering equipment when I first started out to, especially when I grew aero or dwc. I prefer soil these days only because I live in an area with unfavorable water but even still I use no equip. with my soil girls and have NO problems at all. I use basic GH nutes and even sometimes cheap NPK shit from the store and it works awesome, I can promise my buds have the MOST amount of crystals I have seen in ages with only 25 days or so flower. If i was doing hydro I prob. would use my metering equip more, just my 2 cents man, I hope i said something that can help you, and like the gentlemen above me and I said, use the finger trick and as you do this you will get a knack for it, I promise, Good luck dude..
