Your EC is way too high and she's struggling... plus, the ratio between the Flora Gro, Bloom and Micro is off .... it should be 1 part Gro, 2 parts Micro and 3 parts Bloom... and your pH is a bit too high... dial that back to 6.0 max. Good luck! Nice looking grow if you can get the EC and pH under control!

Issues with trace elements/minor nutrients (immobile nutrients) like manganese, zinc, iron, copper, sulfur etc, show up in the new growth first. Issues with macro nutrients (mobile nutrients) like nitrogen, phosphorous and potassium, show up in the oldest leaves first. I would say you have an issue with not enough potassium for this stage of grow.

My guess is a manganese deficiency or lock, due to a ph too high.. Manganese is best absorbed in an acid solution and it's immobile, so you see the problem on the old leaves. My advice is to turn pH under 5,8 for 3-4 days at least and then swing between 5,8 and 6,3 max. Good Luck

Does anyone think that my girl will recover from the recent nutrient burn? Has anyone got any tips or advice they could give to help her continue to grow consistently? Thanks.

White Widow runoff water tests at 2440 PPM, but seems happy still and is only showing very slight signs of burning. This still seems extremely high, so I've backed off on feeding for now and watered with some Cal Mag. Should I wait for the PPM to drop or keep feeding her at 1/4?

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

The lower leaves of some plants are yellow, then die. I'm very light with nutrients, there is no bugs into the grow room, what can it be ? pH between 6 and 7, lower it with few drops of lemon juice but bought a 3aciddown bottle. And are the buds supposed to be that big already ?

I have uploaded a few more pictures - getting worries as the yellowing is continuing. Any ideas? pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down.
