My best growing tip would be to have patience. I know you want to get i n the garden and do stuff. Sometimes you just have to LITFA. Also, most new growers are very excited for their first crop and may chop too early. Just be patient and it will most certainly be better.
Seeds produced outdoors have tons of vigor, you can also put your clones outside into the earth for the summer and take cuttings for reinvigorated clones indoors.
When you think your soil is dry, lift the pot and feel it. Water it slowly but thoroughly. I like to fill a 5 gallon bucket and use a solo cup to water with. Add your water very slowly, a cupful at a time, and give it a few minutes to soak in before adding more. Otherwise it will run right out the bottom before it gets a chance to absorb. Once everything is soaked up, lift the pot and compare the two. A lightweight pot needs more water than a heavy one.
If the top is crusty, it’s probably overloaded with salts. Remove it and add fresh potting mix. If the rootball constantly draws away from the sides and you’re watering daily, you might consider repotting it.
My tip would be to invest in good lighting above all. Before overgrow, I used to tell people to invest in good genetics, but now I know there’s amazing stuff by members on here for free.
Best tip I have is that you have to resist the urge to fuck around with the plant when you are bored, just let it grow and feed it as it requires, not as you want to.
Let your fresh cut clones soak in a cup of water/clone mix for a couple hours, before you put them into the rooting medium.
You gonna be able to write a grow guide from all the great tips on this thread @PhlizonGrowLight !

My advice is that cal-mag is not the only solution to calcium/magnesium problems. Gypsum (calcium sulfate) and Epsom salts (magnesium sulfate) are two great ways of adding calcium or magnesium separately to address deficiencies.
