Hey Weedhound,
Ok ill stop flushing and put the pump back on the timer... I flushed three times with each time consisting of one gallon phed to 5.8...My reservoir had 12 gallons of R/O water so I looked at the firefox hydro feeding schedule and it said to mix 2 tsp/gal of grow big and 1tbl/gal of big bloom so I did the math out and got 120 ml of GB and 180ml of BB. Then I didn't want to do full strength so I did half... as for the calmag it said to use 5-10ml/gal so I use 5 and got 60ml for the 12 gallons (halved that too). So after the flushing of the three extra gallons it is at 15 now and the ppm is 420, ec is 835, pH is 5.75 and temp is 68. These plants are now 28 days old since the sprout broke through the rockwool and im not sure what kind it is... I got the seeds from a friend who grows outdoors (could that be the problem?). They are asleep right now but they still look good... they are still growing larger every day, like its growing away from the problem area. Ill post some pics tomorrow Later
