You should know within the first week when you give the plants the Verti
nutrients if the plants will survive. You should see a drastic change if it works. I’ve used M Grow once and never successfully gone to a full cycle when plants showed signs of deficiency. MGrow works great in the seedling stage up to maybe 1 ft then but it doesn’t have what’s needed for massive fruiting. I start the Verti nutrients. Still keep your fingers crossed it should work since you don’t have a lot of fruit forming.
Keep some suckers on clip the browning leaves keep the yellowing leaves if they look healthy as they will let you know if the VG nutrients are working.
In case you see within the first week no change in plants when switching to VG you can still salvage some things. You can clip the longer suckers put the stem in rockwool cube and put them in the
aeroponic seed starter you built with a little bit of nutrients. They will form roots quickly so you will save yourself 45 + days with work if starting from seed.
