Watering and darkness before harvestI've been giving them just water for 2 weeks but I only let them get about 10% runoff. I want to put them in 48hrs darkness but not if they've just been watered. Looking for opinions: flush to 80% runoff now and harvest on Wed or leave them in darkness and cut them down on Wed?5y ago

what EC do you feed and how often?I've been giving 6.5 pH water once and the next time I add nutrients until I get an EC of 1mS/cm. This was ok before (runoff didn't show many nutrients on soil). Now I water 2.5L/day but the plant leaves nutrients in soil (runoff EC increases rapidly!) It's in week 4 of flower.5y ago

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.5y ago

Soil pH not adjusting even after watering pH water.So Far I've been 6.5-7 pH water, & organic ferts BioThrive Grow, Bloom & CalMag. The soil pH doesn't seen to go any below 6.5; even though I've been feeding 5 pH water to make it lower. Why is this happening? What to do? Does organics in the soil auto-adjust the pH all by itself2y ago
