Beginner indoor

Can you specify what piece of advice you need? Could be anything honestly and its way too complex of a topic to give you a general answer on what to do here. I would say watch some youtube videos or read a book if you have no idea in general, otherwise please specify your question and make a grow report.

What advice do you need?

i'd add more perlite to the ocean forest stuff. soil is like riding a bike, so take note of what you are doing and when you are doing it. the soil will probably feed your plants well for 4-6 weeks or more. then you have to slow ramp up fertilization to supplement it. this is the learning to balance part. if you want do it conservatively, start with 1/4 strength when you start to see a hint of deficiency on lower leaves. take note of how many days or weeks into grow... keep adjusting up only if you see a deficiency creeping in. It's always easier to add more and incredibly more difficult to deal with a toxicity. After the grow you adjust the timing of your ramp up to hopefully avoid any issues creeping in over time... seeenig the true outcome of our fertilization choices sometimes take a week or even several weeks to see the full outcome of that adjustment. the slower moving the symptoms are, the smaler the adjustment necessary. just gotta do it.. with soil, too many local variables are different to give a one-sized-fits-all on exactly how to fertilize.
