Is my plant stunted?

Well you are not watering correctly for a soilless context. 1) Always fertigate and get 10% runoff 2) wait for top layer to start to dry and repeat. you should be providing 100% of nutritional need every irrigation. It should have 10% runoff or more every irrigation to avoid buildup over time. You do not whimsically choose the volume nor the increment of time between. You give what is needed and you react to some minimal dryback that avoids problems in rootzone. Why is it 'different' There is genetic variety even among a single strain. Also, you may not be giving as much light or as well of a controlled environment. Your poor watering habits may have slowed it down, too. Maybe the fertilizer you have isn't as well-rounded as it should be? There really are numerous and seemingly endless reasons as to why one garden has different results than another. is that an outdoor plant? if shifting between outdoor and indoor that's going to be hard on the plant. if it adapts to the sun, the lights willb e too weak, and if it adapts to the light the sun will be too strong (usually.. depends on region). The funky lower leaves are probably related to the odd watering habits.

Why everyone gotta complicate shit with coco lol. The amount of airflow one needs to cause the windburn is substantial, she is altering the leaf structure to make them more aerodynamic to better deal with the stress you are putting her through. I know from experience how much airflow that requires. Increased movement of the air around a plant will result in a much higher transpiration rate. The rate at which the plant releases water in one way or another should match what's going into the medium, what goes in must come out. Should never blanket watering just because. How often you wayer should be based on a number of variables, but I wouldn't expect oxygen to be a problem In coco bit something is disrupting her release. I'd love to know your ec of medium and both your day and night temps and rh%, with that I'd be able to better understand what's going on under the hood. But right now all I see is a plant under too much prolonged stress from too much airflow. When the stomata senses high airflow it increases transpiration, while increased airflow can help to increase Vapor Pressure Deficit (VPD), it's not a direct causal relationship. Airflow primarily affects the boundary layer around plants, influencing how they experience humidity and therefore VPD. Plant is experiencing extremely high vpd this triggers the signalling of guard cells to close stomata to protect plant from major environmental water loss. With gas exchange slowed/crippled, waters not leaving plant through daytime transpiration this will slow everything down. Eventually if waters not moving, salts not moving and your entire pot is at the mercy of evaporation, that is entirely dependant on the environment you set for yourself. Anything above 60%rh indoors will not promote evaporation. As soon as transpiration runs into a problem. We all have problem. Gluck

Definitely agree with everyone else you are giving too much water poke you finger into the soil about the first knuckle deep or so and see how it feels in that first inch of soil if it’s still moist don’t water when you feel the soil and it is dry you want to water also I recommend picking up your pots on a daily until you get an idea of what a put full of water weighs vs one that is empty I really hope that helps your plant out gromie.

Perlite + Coco ist too much staying water !! Stop giving them too much water, just wait few days after u give them water. Give them next time 1 time water with correct ph 5,5 on coco

I would check Leaf temps , soil temps and going to guess it doesn't get direct light for 6-10 hrs? On the plant + pot ? Little over watering Cut the watering ,let it dry back 80-90% then water and leave don't water untill nearly dry again. Use back of your hand or fingers ,dig down into the soil a few inches ,if it's cold it's wet (doesn't need watering) If dry and warm (needs watering ) Learn the weight of your pot when fully wet and nearly dried back then you only have to lift it up to check if it needs watering or not Get that bitch in some sunlight

You Need to give the plant water only when It Needs It and sometimes even e dry period. You only water when the soil if Its dry in the whole pot or at least 80% dry. I grow indoor and outdoor and if i over water this happens to me because some phenos drink a lot of water and some dont want any at all like my Pound cake grow i only water every 8/10 days outdoors

I would guess too much water. But Im newbie, so wait for other opinions.
