I am growing in rockwool in a modified flood and drain system with a 20 gallon reservoir feeding 8, 3 foot trays. they are lit by 2 1000 watt hps. My water is 0 ppm from a RO unit. my nutes are GH, i am using 5 ml of micro and 7.5 ml of bloom per gallon of water. my feed solution ph fluctuates between 5.6 and 6.0. the plants are from seed and they are approx 2.5 weeks old. the ones showing the browning and spotting are strictly the bogglegums.
the rockwool was soaked and rinsed per grodans instructions.
here are a couple pics, please let me know if i am missing any information.
