You list the weight of your water but you don't mention the pH? And you don't have a PPM meter which you need; I'd recommend you get a pH and PPM meter asap & go from thereHello all,
This is my firs grow and it's not going very well so far. I have feminized Bubba Kush seeds that germinated right away and sprouted out of the soil the day after I planted them. After that it's been down hill. See pics below.
Below is my set up, I am using a 3 x 3 tent in the basement which is very dry 35% humidity normally. I had to add a electric oil heater to get the temp's up to 71 deg F. I have a humidifier which is on 24/ 7 (unless I don't get to it in time to fill it up) but still humidity is only increased to 40-45%.
My exhaust fan 6" is on lowest setting the fan controller can go, but even on low it seems to suck all the humidity out of the tent too fast. If I turn off the fan it will climb to 50% fast, but then I am not getting the air exchange.
I am not sure if the drooping/ slow growth is due to over watering, under watering or light too close or soil is too hot?
Water - is filtered through a Pro-Pur gravity water filter. It is supposed to remove chlorine and other toxic chemicals. It is not RO though so I don't know the PPM as I don't have a meter.

Soil - Pro Mix Organic Vegetable and Herb Mix. https://www.promixgardening.com/en/product/detail/promix-premium-organic-vegetable-herb-mix
Pots - Seedlings are in a small pot that has openings at the bottom that is supposed air prune a good root system. It's called a root maker pot.

Light - LED Apolo 10, 450W Claimed Draw (I don't have a way to measure) 337 - 364W
Fan - 6" with controller turned all the way down to lwoest setting.
Intake - passive, one 8" one 6"
Fan - 7.5" oscillating sitting on the ground for now.
Humidifier - on always
Heater - Oil electric heater keeping temps from 70 - 73deg f
I initially thought I was over watering but then thought I may be under watering as the soil will dry out fast I assume due to the low humidity?
I started weighing the pots before and after water as follows. I filled one pot with just soil out of the bag and it weighted 183g. The pots with the plants in them I would wait until they were dry and weighted 150g, then watered with 150g of water to a watered weight of 260g. Wait until they are down to 150g and water again,.
Control pot:
Filled with soil out of the bag 183g
Pot 1:
Watered 263g - Dry 151g
Pot 2:
Watered 265g - Dry 156g
I developed this method to make sure the soil was actually dry before watering.
Light - manufacturer says 30 inches from plants for first 7 days
Day 7 - stretch 24"
Stretch16-18" from top of plants
Flowering 12-16" from top of plants.
I was following this but the thought maybe the light is too much for them and that is the reason for slow growth and curling leaves? I then raised the light to 30" and now it is at 35".
Lux Meter (phone app) is showing 23,000 at the top of the plants even at the 35" distance. Is this too much light? Is the phone app on my S7 accurate?
Below are the pics of the plants and the set up.
Please let me know your thought's on what is causing them to droop and grow slow?

Any help is greatly appreciated.
I recognize the fan , is it an elicent brand ?
The grey filter inline fan on top.....
Aim that black fan on the left somewhere else, bad habit , in my opinion to direct air on top of young plants...
The whole temp management thing you got going , heat , hum , etc could be a little rough, might need a different tactic...
down size your filter fan combo while you veg,in veg temps up to 85 and humidity the same is a good thing,so turn the exhaust off be what id do,unless smell is a issue and i dont see that as a problem since your filter isnt hooked up.that oil heater is too close to plants and i would only run it lights off,what is your plan for getting them plants out of the pot you have them in ,ive never seen anything like that,and see a big problem getting out for a transplant.
your soil is fine but loaded with nutes for 3 months,so id suggest taking it easy when you do think you need to feed,far as the dry thing,pro mix is peat moss,let me state this difrently,i dont let pro mix dry or coco,with both there should be a exchange of air and nutes daily IN MY OPINION,be surprised with the arguments hahahah back on track,but your weighing your pots,that cool ,are you adding cal mag with your water ,i see you have a system to take out minerals those have to be replaced so when you water check your ppm it should be 100 to 25o ppm at the seedling stage you are at,if your drainage is correct and you have adequit air flow you should water daily in pro mix and coco,it need the exchange of airto your roots,again this is my opinion,the drainage should have your media moist but not soaked if you dig,the heater for sure needs moved away from the plants,the plants need to be off the floor and on something they get cold,turn off exhaust and run your humy,maybe that enough to throw around in your head ,maybe use some of it ,good luck mate
I am not sure about the slow growth/droopiness but I do struggle with humidity issues especially in the winter when the fire place is going. When I am in veg I have been turning off my exhaust fan and then I put a small clip-on fan in one of the side holes on the tent. This seems to allow for good air exchange but not so much that it pulls all of the humidity out.
You list the weight of your water but you don't mention the pH? And you don't have a PPM meter which you need; I'd recommend you get a pH and PPM meter asap & go from there
My mistake i thought it said dehumidifierHey thc monster, dj said he has a humidifer running , not a de humidifier
And he said his humidity is 45 to 50 %
i work at a Hydroponic Store and would like to throw my 2 cents in if you'll let me!
First thought is that 35% humidity is way to low for veg, you should be shooting for 40-45%... If you have really good air flow then shoot for 50% really! I would stop running the dehumidifier for Veg! Your leaves need the moisture! But make sure u have really good air flow... Run a couple wall fans (not just your inline exhaust).
The drooping I could probably say is two possible reasons
1) the humidity is too low and your dehumidifier is literally pulling out the moisture to your leaves, if your leaves fell kind of rough to the touch then this is probably the issuw
2) chances are your over watering or under watering, if they are not dry when they droop then you are over watering them but usually over watering causes leaves to curl inward (the opposite of an eagles claw)
Limit the amount of water you give your plants! I cant tell you how many customers of mine come in with problems and its because they are trying to water their plants like they are trees when they are really just tiny little plants!
Unless you are giving them liquid nutrients/fertilizer i wouldnt flood them with water when you water! Being in promix you want to give them just enough water to get through 2-3 days tops, 3 days still being pretty long in my opinion! You have an LED thats why you are having problems with heat. Cause they dont produce much heat they are harder to grow effectively in the winter time with!
Just try to bump up the temps to around 75-77 if you can.
DEFINITELY Bring up your humidity for Veg 35% is WAY to low.
And get more ambient air flow (wall fans) to dry your plants out quicker
And limit the amount of water you feed your plants, give them just enough to get them past 1-2 days. They will grow better and faster! Do a flush every 3rd or 4th day.
Hope this helps!
