Yes, FF green bag and BioBizz... I have some Plagron shipping ^^ and want to test that.. just for fun. No supplier local.. I wouldn't wanna depend on Post Office.
That is rather simple.. as I like to feed rather more then less. I watch the tips of the leaves. They tell me when to go water but at the end is learning a strain.. not learning to grow. You can do a dialed in grow on your first run of a new strain you test.. but that is rather unlikely. In general you need a few to get all the "special" parts of the strain.
But my general routine is daily. I lift each pot to know who needs water. If I have the same strains in a tray, I usually just lift the most thirsty and not so thirsty. That tells me to mix a bucket or no. Tray feeding makes the feeding simple.. not helping to really get a perfect result. If you aim for the best, you have to give each plant a few seconds of your time a day. The Gelato I played with now, has its own tricky part.. can't over feed them or they revolt. So cut down 25% nutes on those an had a very smooth sail. never gave 4ml of anything.. beside the flowering stimulators
As I feed each time i water, I expect more to run into over feeding issues, then under feeding. So the first change is always pure water. That deals with the over feeding symptoms for your feeding solution. Next 2 you can run into is Mg and Ca deficiency... you find pictures on the web.. Ca can also relate to white dots forming on the leaves.. not as easy to find, so I add it. Internet pictures should be your first go to. Or make some close ups and post here.. if in doubt. Not often you run into Fe issues.. fresh soil, you never ever should. Mg comes up most, if not one of your NPK culprits. Ca behind.. Fe.. you really have to use strange stuff
Once you grew a strain for a few times, you will actually learn yourself what to do and what they dislike. Is the reason I run grow sheets.. to know where to look, if I run into troubles. Once I am happy with my result.. I also don't run a grow sheet anymore on that strain and just use the information i learned before.. I am just a amateur at the end and have fun with what I am doing.
When you start racing a car.. you don't hop in and after 2 laps you challenge a F1 Pro. You do laps and improve, the more you do on the same track, the better you become. The more tracks you drive, the better you get on those tracks. And dude.. you will crash some cars, if you want to become a professional racing driver Experience helps... after a few hundred plants.. thank god, some mistakes I learned to avoid
My first go to is always the internet picture section.. you know how your issue looks like.. search and trust your eyes. On the way you learn a lot more as just how to solve your issue. You read and judge if it just makes sense.. common sense is all you need growing weed.
Indoor you can mess up a lot more as outdoor.. strange but true Crap light.. crap results. Crap ventilation.. crap results. Crap climate.. crap results. Indoor you have to check a lot more factors then outdoor... so you just add those to the indoor checklist for the strain
