I accidentally gave my plant too much pH Down, due to a faulty soil meter. I got a lot of help to get the pH to higher. pH was 4.98 and I found out it had nutrient lock out. Yesterday, I, guided by a pro, leached this with several gallons of spring water (7.8 pH), and took pH readings of gallons, and I saved a litre of spring water and added 1ml FF Grow Big, to feed a little after leaching. Next time I water, it will be with a dose of just all spring water. Fingers crossed, it recovers.
