high man, first let me say welcome to the hobby and let me also assure you it is well worth the effort required to learn to grow successfully and reliably.
...now, as a brand new grower the first lesson is for you to understand, in your gut, that this grow isn't important except as a learning experience, even if that means you've learned some of what NOT to do, so long as you learn from this experience, it won't have been wasted time, even if it ends in 'failure' you will still have yielded much knowledge and experience.
anyway, you should know that Miracle Grow isn't so good for cannabis, some do ok with it but some have tremendous trouble, especially the inexperienced and being new i'm sure you struggle with when to feed them and such, ...in the beginning it can be awfully confusing.
so my advice is for you to take a mulligan of sorts and switch your style from a sometimes unforgiving soil grow to a stable and easy to run passive hydro technique called 'hempy buckets' which are an adaptation of ancient Roman technology that is brain dead easy to run and will produce some amazing results, more importantly, because they are so easy and stable to run, you will have the time to relax and learn to watch and read your plants.
anyway, here are a couple of links to supply's that you can have shipped from Amazon for small money that will do the job nicely for you as they have for me these last several years.
...and some examples grown in coco hempy's that were fed nothing but MaxiBloom from rooted clone right up to the pre-harvest flush.

note also that these were grown in 2liters of coco only, that first pic is a pair of White Rhino's that yielded nearly 2zipz each.

anyway, if you do some research you will find much information on the technique, be sure to avoid any advice from anyone who seems wedded too deeply in dogma, the technique was introduced by a guy who calls himself '
hempy' or '
dalaihempy' and while he has some skills, there are some sycophants who are best ignored, generally speaking, they take issue with ANY deviation and create trollish turmoil thereafter.
peace, SOG
