After 3 months of veg I flipped to flower making this the last week of month 2 of flower so it shouldn’t be to much long till I can chop them down. One plant looks pretty solid and they just need to stack on a bit more weight but the other three still need a couple more weeks. Had a lock out issue for a week or two around week 16 so I did a heavy flush and got it down to a decent ppm on the run off and since then I’ve been feeding them at 1/4 strength and have been doing much better with the run off and leaf issues. I would only imagine the roots are fully root bound by now and have sucked all the original nutrients out of the soil and is strictly feeding on what I’ve been giving them. I’ve been bouncing week to week from just feeding them dual fuel 1 + 2 one week and the full 2 part nutrient line the next week.
