I did not anticipate as many problems occurring as they are. First nitrogen deficiency, then what seemed like a mag./sulphur def., and now whatever it is that's affecting my plant (I have no idea).
How many issues did you encounter when you did your first grow? Is this normal for a grower to experience this many problems when they grow pot? I chose soil to try and absolve myself of more responsibility, and now I'm not sure if I made the right choice..
used to have a lot of issues. Mostly they came from not being able to keep the nutes consistant, and from not using a live soil designed for cannabis.
There are great tutorials here, and many seed banks also have great tutorials on their websites.
I did not have consistantly good results until I started giving the plants what the plant needed.
Every aspect of your grow is critical. It is called weed, but it only grows like one under the right conditions.
I will name some brands, but there are others just as good.
So what are the right conditions?
The right soil.
What gives me the best results for indoor is FoxFarm (FF) Ocean Forest mixed with FF Happy Frog and perlite. It both holds water easily and flushes well, and has the perfect blend of organic nutrients to feed a plant through the first 30 days.
The right water.
At a minimum, you must stay between 6.2 and 6.8 pH. To acidic or too alkaline will prevent some nutrients from being picked up by the roots. Keeping the water pH balanced will allow the roots to do their jobs.
I use a reverse ozmosis filter for my water. Its really unnbelievable how many little issues with nutrients that solved. My water comes out at 6.4 pH every time, and without all the aditives and trace elements, there is nothing that I do not account for in the nute mix.
You have to keep the roots wet, but not soaked. When they are too dry, they cannot absorb anything, and if kept too wet in soil they will rot. Use the fabric bags, and water till there is the first trace of runoff. Water when the soil feels dry two inches down.
Nutrients.
Use liquid organic nutrients that are formulated for cannabis. Start the nutes at day 20 on the light feeding schedule. At day 30 move to medium feeding schedule. Use nute mixes formulated for the stage the plant is in. Veg food, flowering food, and extra Cal-Mag or straight Mag from first sign of flowering.
Again, there are a lot of brands that are good. I use FF Grow Big for Veg phase, Big Bloom and Tiger Bloom, and FF Bushwacker Cal-Mag during flowering. I also use the original Bud Candy.
I feed two waterings out of three, and start the Bud Candy when I switch lighting if photo or at first sign of flowering if auto. The Cal-Mag is once a week.
Humidity and temp
Pot has an optimum growing temperature range, but as long as there is sufficient air movement and the humidity is right a little out of temp range can still work. Absolutely the grow room humidity must be between 40% and 65% RH. Use a dehumidifier, oscilating fans, and a good exhaust fan.
Lighting.
Get a high quality LED bank with a flowering coverage 1 foot larger than your space. There is no such thing as too much light density. You want corner measurements of at least 1100 lumens at 20". If possible get a light that has a veg setting and a flowering setting. I use a grow tent to control both inside and outside light. If you cant get a tent, line all surfaces in the room with mylar.
Just following those steps will eliminate all the issues you have had. If the idea is to be responsibility free, growing might not be your gig. If the idea is to keep it simple, using a single brand for as much as possible will reduce chances of nute imbalances.
If you do all this, it can be simple. However, it is a daily task. Every single day.
Two other common issues are mildew/mold/rot and insects. If fungus issues arise, go to a nursery and get a bacterial antifungal spray. Safe to the day of harvest. Bacteria that can only eat fungus, spores, and mitachondria eat till its gone and die. No residue.
If you get bugs, buy ladybugs or preying mantis.
Other than that, read as many tutorials as you can. I've grown since the '70s and am still learning. It does get easier...
