Hi there, my plant is on on week 3 of flower, grown in a 50/50 happy farms ocean floor/happy frog mix. After recently feeding it 3mL of general hydroponics grow, 8ml micro,14mL Bloom in 1 gallonof tap water they are beginning to show signs of a nutrient deficiency/toxicity. I water without nutes at ph7 but then runoff is consistantly ph5. Do i add ph up to balance this out or continue watering nornally at ph7? (First grow)

Have you ever flushed they may have salt lock out a flush may help but it also maybe cal mag or even light burn.
I have been growing long time in soil never once have i ever added a ph up or down only in hydro.
And even though you said you feed them they may need more also.
At three weeks are when plants really start to take up potassium and phosphorus.
Calcium and magnesium also.
I personally use tiger bloom in happy frog and nothing else not even big bloom i feel it messes the uptake.

Thanks for your input! I have never flushed my plant but i think there may be a salt buildup or something of the sort and it may be called for. If the runoff is at ph5 that would also lockout n-p-k as well as cal-mag. Do you think a flush 3 weeks into flower would be incredibly detrimental? The plant seems to be getting worse very quickly starting at the bottom of the plant.
