@sgtPeppercorn I've been a grower for 7 years in the legal industry and I have BS in Botany and Chemistry. I've also been a wholesale nursery manager for several years of my life. I frequently hit 25%-30% THC but what do I know?
Just because I only have a few posts doesn't mean I don't know my shit. I've been lurking on this site for a while and only recently became active, but egos like yours make me not want to share the tricks I've learned. Go smoke a bowl and check your attitude friend. We're all here to help her and you are kind of being a dick to me for offering help. You might learn something if you drop your shields.
7.0 (neutral) is still too high. She said she was using RO water if I remember correctly. RO has no nutrients in it whatsoever and its pH sways wildly. You can get away with a week or two of no nutrients on city tap water but if you want your plant to actually grow then you've got to give them something to eat. Obviously growing in soil and hydro are two different animals, I've done both successfully. pH is critical at every stage of a plant's growth. Improper pH can cause the roots to not be able to uptake nutrients and can even make the osmotic balance reverse so that water flows out of the roots instead of into them, causing them to dry and die, killing the plant.
@ThatCrazyStonerChick If you want to have great bud with minimal effort, always pH your feed solution as well as the runoff. If you aren't collecting data, and something funny happens to your plants, you won't be able to figure out what it is and it will be harder for this forum to help you. You sound like you need this run to really be successful. You can trust that guy, or somebody with experience, your choice,
Simple Soil That Worked For My First & Future Grows
A pH of 8.59 is way out of safe limits. I promise, aim for anywhere between 5.7-6.3 with a light feeding of N, P, K, Ca, Mg; aim for ~200 ppm TDS. The soil should have the rest.
