-Temperature-
Are you swinging your temps? At 82 you are pushing limits on temperature without CO2 supplement.
I ran a hot grow my first run with a CO2 bag. Growth was fast, but if I ever swung above 82, she stunted. My lows were mid to high 70s. Growth was noticeable at night temps in the 70s and slowed or stopped during the lights on hot temps of 80+.
With that being said, there needs to be a swing. Temps need to be lower than 82. Humidity will be high with high temps whether you like it or not, dropping temps is the only way to keep humidity in check. Swing 5-10 degrees but stay below 80 max temps.
Someone said something to me along my beginnings “use or create a grow space that Does Not have a steady temperature and naturally swings without intermission”.
-This is why a room in a house with central air is a poor area to grow. You must create the swings yourself and makes it incredibly hard to manage.
To achieve this in a room with central air you must use dehumidifiers and A/C units and shut your vents to that room.
-Nutrients-
I’ll say it because I use it and it’s foolproof,
General Hydroponics Nutrients. Their feed schedule is fool proof. Follow it to a T and you can’t be wrong if your soil is basic soil. Coco will just make you sick of growing, mixing soil is not for beginners or anyone looking for a dank grow without experience. These products are fairly cheap and you only need 4 of them to complete a grow. Add more products as you go to get better buds. (Given Temperatures are in control). Last thing anybody needs is deficiencies/toxicity from failed mixology.
-Light-
Your lights are fine, but you must control the temperature they are creating. That is key for the type of light you use. Forget about PPFD, that technical crap will have you chasing numbers. Wait until your environment is handled before you go down those rabbit holes of chasing technical stuff.
-Find the proper light distance for the type of light used and Maintain! it. Measure that distance every day and move that light up if she grows an inch.
-Airflow-
This is not just airflow or wind creation. This is induction and exhausting. You want negative pressure, which requires more outflow from the room than inflow. This also creates a more stable environment when you want to maintain temperatures, by altering the intake and exhaust fan speeds, being able to lower heat (increased exhaust) or increasing temps (lowering exhaust). You can play with these two fans while used in unison to stabilize a temperature target and maintain negative pressure. Ie: 4”intake 6” exhaust or 6” intake 8” exhaust. The floor fan is only to be used for balancing the air within the room and keeping the whole room the same temperature, with no hot spots. It is not a cooling device.
It isn’t the plant, it is the conditions for which she is being grown. Focus all these items, focus feed and do not touch them. Enjoy great weed if you stay focused only on these listed principals. Nobody can give you better advice. This is the truth of success, everything else is too specific and you shouldn’t base your success on a few suggestions. Although these guys know what they are doing, your experience level and $$ investment is not allowing you to make hefty changes that would create ease of growing.
Temps temps temps. That’s your challenge in a room in the middle of the house. 75degrees/50 or less RH veg or flower, foolproof feed chart and nutrients and you have chronic.
