High PH soil how to fix it?

Para bajarlo, con algo ácido sra vinagre o limon, tu elijes. Sugiero hacer como um lavado de raízes con pH6.5. Hasta que veas que el Runoff sale igual a ló que lê metes, En este caso, 6.5! Aun asi, acuerda-te que tambien puedes corregir el substrato com humos y hongos benéficos que te ayudan a mantener el suelo perfect. Para medir el pH del suelo con más detalles, echale um poco de substrato En un recipiente y com 2 partes de água destilada, dejalo que repose mínimo 12h, filtralo y mide el pH 💪 espero haberte ayudado

My water PH is 7.4... I use just under 2ml of lemon juice to 1000ml water (1litre) never had a problem since... and I'm ready harvest in 2 days

@NobodyBuds thanks. I tend not to allow any run off since they started, and that is probably what has happened is its not running anything off the soil and allowing it to sit within the soil. I'll water properly with a little run off wait tell that 1" becomes dry and repeat while taking a reading to see how things are while watching her respond to it. Hopefully it balances out then begin the feeding schedule again.

definitely fix pH before reacting to symptoms. any acid will do. distilled white vinegar, for example... much cheaper than "ph-down" products. i wouldn't 'flush.' Keep irrigating, but ph-down the solution lower than your target... see what runoff reads.. a few soil slurry samples - not just off top, in fact top is worst place due to extra evaporation, i bet. use same volume of 7pH water and same mass of soil. In both cases, the reading will be inaccurate... context should dictate whether it's actually beyond or short of the reading. runoff is just imprecise... irrigation habits? just in case -- always saturate soil with a little runoff waste. ensures no dry pockets whose impacts get much worse with time - e.g. pH or nute concentrations. Wait for top 1" to dry.. repeat.. keep whatever fertilization schedule you had... and once pH is hammered out, see how it heals... judge new growth for health. remember, it's a logrithmic scale relative to 7... just 1 integer lower is 10x more h3o+:oh-... 2 is 100:1. Try 6pH irrigation or fertilization? while low, it should average out in a safe range. observe results and adjust if needed. N tends to be more available at higher pH, so could reduce that temporarily while you work on pH. could be what you are seeing with the dark green leaves and maybe a bit glossy? if you apply neem oil, can look glossy on its own.
