95%-99% of a plant's water use is cooling, other 1-5% is split for its hydrogen and used for growth and metabolic functions. As the plant cools its leaves during photosynthesis, evaporation occurs; the tiny stomata on leaves perform gas exchange: CO2 in, O2 out; this creates a suction pressure called "transpiration pull" (which results in turgor pressure). In order for the plant to maintain this transpiration stream, it must balance its "OSMOTIC POTENTIAL" in the root zones, which is heavily influenced by "EC". EC.............not just a measurement of feed, but the key driver of the osmotic gradient between two zones (inside the roots and the surrounding soil solution). IF EC goes too high, water flow stops. If EC gets too low, water flow slows down and nutrient uptake stops. EC reflects the concentration of salts dissolved in water. As your medium dries, if the plant is not uptaking salts at the same rate or higher, then salts will accumulate and remain trapped. There is iirc 3x-6x more transpiration happening at 86F than at 70F; that's just temps alone due to the exponential increase in Vapor Pressure Deficit (VPD); now you add airflow x7x8. If your plant has 3,4,5 times the transpiration load in its lifetime, then it's going to move 4-5 times the water in the same timeframe. A plant hit with low environmental demand for its entire life is going to have far less developed xylem and phloem channels than the plant that was getting consistent high-airflow demand its entire life, purely because the amount of water it had to move was 4,5,6x more in the same timeframe. You will find it hard to make your little plants stand up erect without adequate root pressure or transpiration; you would need to crank up the temps to force a much higher level of transpiration. This would create more transpiration pull, and the plant could use the resulting turgor pressure to make its leaves look all sharp and pinpoint, but it's not necessarily a good sign, merely an indicator of stress (high volume of water flow) in plastic pots with such a lack of oxygen. Your plants would only be able to handle high temps for a couple of hours before they crashed; they need much bigger pots and far more oxygen for root respiration. Then you could crank up the environmentals and watch her dance. If you were to conceptualize the plant as a construction site, water is the delivery solvent, transpiration is how fast the "elevator" works, and it has the potential to move massive amounts of nutrients. 5x water =5x potential nutrients, simplistic but applicable. All the best to you and yours.

Plants drooping and recovering usually points to the watering cycle, not a mistake. Droop right after watering means too wet, so let the pot dry more. Droop with a light pot means thirsty. Lift the pot and only water when it feels light, and give it a few days between waterings. If leaves look healthy and perk up again, you're fine.

Doesn't look too bad, not time to worry yet :) Try this: First make sure you have more room for run-off than in those little saucers SLOWLY water with around 1/3 of the pot size, so if those are 11L pots water with 3-4L, add 2ml Bio-Grow and 1ml Bio-Bloom per liter water Once the run-off has stopped move them back in the tent, throw the run-off out When the pots begin to feel light again when you lift them, repeat the process (probably around every 3rd day - follow chart as it shifts towards higher Bio-Bloom ratio) This way you fully saturate the medium which is paramount in soil growing.

Also fill pots to the top or your creating a sweaty mess down bellow....mico climate

Watering to frequent.. the pot and plant size dictates how much water is given but you wan to water once and let dry out enough so the pots are much lighter to lift, keeping the soil wet with dry pockets is giving a bad root structure...

so many different reasons are possible... - too much light, even if they seem okay for a period of time, can cause droopiness. This will hapen mostly at the end of the light cycle. Might get droppy for 1-2 horus before lights go out. This can happen with no light damage visible on leaves and can take up to a couple weeks to display from the onset of providing too much. Not only can a take a while to display visible symptoms, but when you fix it, it can take a week or two to fully snap out of any slow growth, too. Droop alone is a less severe case and should clear up within 1-2 days of fixing it. -Roots drowning is definitely another potential cause.. this would obviously happen when the roots are soaking in standing water etc or the pot remains too wet with no wet-dry cycle (too frequent with irrigations) -Extreme climate. High vpd will make the plant transpire too much.. might cause stomata to close up during day or cause excess uptake of nutrients due to the increased transpiration. I can't see the RH, but 23c is certainly not a problem... only if RH is extremely low and VPD is pushing 1.8-2.0 and higher. Bugbee says over 2.0 kPa, but in my experience 1.8 kPa for prolonged period along with high intensity light will definitely make a plant droopy or even stall out if not fixed. Looks like someone else knows the RH is a bit on low side? so this is definitely a possibility. 1.7kPa is still on the high side, though if that's based on atmospheric temp, you need to offset for leaf temp.. recalc vpd based on air temp minus 1 or 2 C. Leaf surface is cooler due to evaporation occuring. -Poor watering habits... like choosing a volume to give rather than simply giving enough to accomplish the task. This can result in inconsistent moisture in the medium and promote superficial root growth. For that, i'd simply refer you to your own question 5 days ago. Based your description in this question you didn't take mine and others' advice about proper irrigation practices, which is fine.. please, do as you want, but if you continue to have inconsistent outcomes, might want to rethink those strategies. growdiaries.com/grow-questions/93879-drenaje It might not be the poor irrigation practices, but eventually your way of irrigating will inevitably run into problems or at minimum less-than-ideal outcomes.

Hey growmie! 🌱💚 I took a look at your diary and there's something that catches my attention: the relative humidity is quite low. With 23 °C and 39–40% humidity, you have a VPD of about 1.7 kPa, assuming the leaves are at the same temperature as the air. That's pretty high for this stage and could be contributing to the leaves looking droopy. I would try to raise the humidity a bit and also check the weight of the pots before watering, to rule out any watering issues. From the photos, it doesn't seem too serious, but I think it's worth checking both factors. 🌿👍 Happy growing! 💚

Do you lift pots to understand when to water ? There is no predetermined schedule in soil grows, you have to water when pots are light to lift. Why quantities are different ? You have to saturate pots well, without any dry pockets. Collect run off, dont let pots to stand in it or reabsorb it. In diary, plant on right side or in last photo shows clawing of leaves, means too much of Nitrogen. Get into good watering regime and keep feed/ plain water/feed/ plain water regime, which you did right. They will br good.
