Low Ph Run Off

Hey all. Thanks in advance for reading this through and your input. I have a Magnum Auto in week 4 of flower using Happy Frog Soil. I started feeding Humboldt Secrets 4 weeks into veg using less than 1/4 the recommended dosage. Starting seeing signs of nute burn but also some possible potassium issues after the last feeding.
I ran some water ph’d to about 6.5. The run off was significantly lower at around 5.2. Ppm is around 200 and 2900 out.
In fear of losing her, I’m deciding not to give anymore nutrients for the rest of the grow. I guess I have a few questions.
is feeding no more nutrients a good idea? I want to get the maximum yield I can out of her.
What can cause low Ph run off? High makes since if it’s nute burn due to salt buildup, but low Ph?
is there a recommendation for an additive I can top the soil with in assisting flower development?
Thanks All!

Low pH can be caused by a few problems. Perhaps most often. it is caused by "Over Acidity". That may be from your Nutes, or from the soil itself. I would reccomend a little Garden Lime, top dressed. If you add too much that can cause an "Over Reaction", and your pH will "Teeter Totter" back and forth untill you find the balance point.

To avoid this problem, start out with a very small amount - maybe just a teaspoon full (about 5 ml.). If that's not enough try 10 ml., then 20 ml., etc.. But go cautiously at this point. Gauge the amount of Lime you add according to the pH results you are getting. Once you have "Over Reacted" , it's not that easy to come back!
