Hello my Friends, I have three Afghan Kush plants growing outdoors in 5 gal fabric pots, and FFOF soil. the plants started turning yellow, leaves dried up and falling off, over a month ago, if is very frustrating. I always ph the water to 6.5, have around 10% run off. was feeding every 3rd watering with FF Trio, 1/2 strength, then tried boosting it to full strength, that didn't do anything. i did a flush about 3 weeks ago, didn't change anything. but one thing i didn't do, was check the run off water. so last night, i did another flush, i ran the garden hose for 8 minutes with medium pressure, so I would say I ran at least 8 gallons through each plant. i measured the hose water, it was 8.3, and after the 8 minutes, i put the pot in a container, to catch the run off water. all three were different, the lowest was 6.48, the highest 6.8. so what do you think the soil PH was before flushing 8 + gallons of tap water through them? i think the PH at the roots must have been so lower, the plants weren't absorbing any nutes. side note, I one one plant thats in the ground. same watering/feeding schedule, and its beautiful. any thoughts / advice?
