At the very tops I have some red rust looking spots, Iโm not sure if itโs cause I canโt pull the light any higher so they are within 10 inches of the light or if itโs a deficiency, started adding cal mag as I have only been using water this grow. Any ideas what the red spots are?
humm.... pull on the sugarleaves, if they easy to pull out you are having some budrot going on
first sign are the sugarleavfes, disccoloring, getting brown
i hope it is anything elase
Normally i would say its a overnuking with nutes , but i have to look closer
older pictures are in purple light, haard to see anything, but i wouldd go with an imbalance in your grow.
mainly in nutrients.
but pull on the sugarleaves, if they gget loose very easy it is budrot,
