Droop Central

Thank you all so much! I'm still learning and this is all very helpful. After reading through the solutions, I think I have been underwatering, which feels good because I thought the claw down was an overwater. I have been under-nuteing because these are autos and I want to prevent burning them again after a terrible mistake in week 3. I will water following some of the guidelines you've shared. I purchased an autopot system this weekend and look forward to setting it up for my next run, but I need to take care of these ladies first and foremost. THANK YOU!👽

these are underwatered based on your description of recentn behaviour. why are you "drying out" a plant? so.. better irrigation practices in soil --- irrigate fully each time. minimal runoff is a good idea to ensure the entire pot gets wet. you don't ant re-occuring dry pockets that could build up minerals over time due to that dynamic that is easily avoided if fully wet. Wait for top 1" to dry, then repeat the process. any runoff should be thrown outside or down a drain.. don't let a plant sit in it's own swill (runoff). Now, if you also feel the weight of the pot, this is a bette signal fo irigation once you learn it... no more dipping finger into substrate needed. just a simple lift to feel weight... when you water at same point (weight) you will use a similar volume of water and makes planning / mixing fetilizer easier with less waste or carryover... you can accurately mix up what you need. do not arbitrarily choose a volume of water to give a plant... this is the wrong way. you give what is necessary to fully saturate it.. if you do this at same loss of weight, it will be a similar volume each time.. you can only know in hindsight, but if you use same components for substrate in future, it'll be similar. also, i'd suggest a 50/50 mix of perlite and soil. you roots will thank you... this will increase irrigation frequency, fyi, but will be beneficial. research backs this up. so, after you correct irrigation issues... some of the other symptoms should abate. You may need to tweak your mix further relative to plant health, of course, but i'd wait until you water it poperly a couple cycles before assuming what you see isn't caused by the previous irrigation habits.. 58% isn't low humidity.. that's fine. Depending on temps you may want to adjust RH... vpd relative to stage of life being the determining factor of what to do with RH/temps. keep RH below 65% to avoid molds and such... though early on with seedlings or clones it's often better to have higher RH / lower VPD.

A combination of over feeding and exhaustion from growing at 24/0. All cannabis plants NEED sleep to finish their daily photosynthesis cycle and have a properly functioning metabolism. A plant with an incorrectly functioning metabolism will NEVER grow to its full potential. The MYTH that it is ok to grow cannabis for weeks/months without sleep needs to be removed from history ASAP! For the sake of yor plants health, please go to 18/6 and give them the sleep that they need. A deep watering to run off would probably help too.

I've seen this caused by a calcium deficiency, and by amino acid overdose. Could it be that they're drying back too far and the Calcium has consiquently become partially unavailable? If there is a salt component to your fertiliser, the salt concentration in the soil increases as moisture decreases - could be salt induced osmotic stress from a dry back?
