sounds fun sseems everybody is just busy busy everywhere i look i see shit to do, literally every w-h-e-r-e!!! well except spiffy shes perfect no need to fix anything on her, (and im going to omit the trashy lewd remark about tweaking stuff under her hood)
hopefully your brother will be so happy to be home he is a good boi and hab had a positive effect on him!! no not "hopefully" im sure thats how it will be im just gonna be 100% positive there!!
im not sure there bud , if all tests are in the green zone i would be wondering about my ph meter, i have 4 ways to test ph so i "know" my reading is right, i always do an enviro check,pests,disease, etc, i had a problem a while back that was making me nuts i was having die off rapid, yellowing and necrosis overnight every test was good ,then i was sitting there watching my blueberry gums die before my eyes, i looked down at the tea bucket water fresh and still and i noticed "oil rainbows" on the surface then i noticed the lower 1/3rd of the 5 gal homie bucket was discolored upon close examination i discovered the plastic was deteriorating evidently releasing toxic thalytes or bpa or something oily, so i swapped out for a new one and after a few days things got better, so my guess these was something toxic to plants was leeching into my tea, now i get a new bucket everytime it starts changing color, ultimately i am going to get some food grade plastic or better yet a couple glass 5 -7 gal carboys (used for beer brewing) hmm i just remembered i have a 5 gallon fish tank, perhaps i should use that,
as far as i know using ro water should not be a problem ,but if you do see a calmag type issue its good to add a little calmag, i always use a little garden lime the stuff from homie d, and i use tap water, im growing in coco so there are some specifics for use, i dont know if your in soil or coco, if soil what brand? as for trade i dont really have any soil beyond some "earth gro" cheapo from homie d, i use for veggies outside, , are you using root magic or some other form of mykos, to break down the organic nutes? they will not perform well without them,
i think if you started a few plants out following the bpn schedule in a good quality soil or coco, you would be pretty happy with the results, thats when i really saw how good they are was a fresh start new beans/clones,soil,follow the plan, and a little communication with corey and i was a happy camper, hope that helps and you get it all ironed out
