If your tds remains stable and have a downward trending ph, it sounds to me like you have a strong reaction between your nutrients looking for equilibrium at a lower ph. The byproducts of these reactions are most likely insoluble and therefore the plants start to show deficiencies.
I would suggest trying to eliminate one nute at a time untill the problem goes away. Also, oxygenating the water speeds up these reactions, sometimes.

When to start my flush (lots of close up pics)I'm curious when I should to begin flushing one of my plants. I know I don't have a diary for her, but she's in her 6th week of flowering starting her 7th week on Wednesday (August 5th) and from what I've read Dread Bread takes between 8-9 weeks to finish. Any opinions?Other. General questions

Brown spots on bud sites leavesHi all,
I’ve been getting these brown spots in the past 2 weeks, mainly on the top leaves located nead bud sites.
What could this be? Ph is ok, I’ve already tried to flush her, Rh is around 45%.
This is day 65, ~20 more to go. Will this affect the bud formation or quality?

Proper feeding questionQuick question. How do you outdoor growers feed. Ex.g,
Say I feed a gallon of mixed PHed nutes to my crop. Do you water as well? What if the soil is already wet like from a rain? If so before or after the nutes? I've looked online EVERYWHERE and cannot find an answer. ThankWeek 23

Did I give too much fertilizer??So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).4 years ago

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.5 years ago
