I've had great luck with slow release nutrients, because it's water soluble as long as you don't over water your plants, you don't over feed them. I probably would have gone with the seed starting soil in a smaller pot then transplanted into the mg organic once it was a little bigger and could handle nutes.weed is essentially a weed and does not need slow release nutrients it just needs normal soil and nutrients when needed.
if it's the plan in the picture probably not, you won't need to water for a few days. it really depends on the type of soil, the lights, the temps, how big your plant is, how big your roots are. a good rule of thumb is to wait until the plant droops a little bit, then you know it needs water. pick up the pot and see how heavy it is when the plant starts to droop, now you know what it feels like when it needs water. then after you water until you get a little run off feel how heavy the pot is and you know what it feels like when it doesn't need water.should i water the 1 in my closet? its been a day?
I agree with the part about the perlite. Disagree with the MG. Nothing wrong with it; it's cheap, it does the job, it has nutes in it and you can find it just about any place that sells soil. Whats so bad about that?Get rid of that MG soil dude get yourself a quality soil..... added perilite is always good that soil you have now is way too compact ....
