i have a few sprouts growing in a waterfarm system. they are under 2 40wt cfls(8in away) and a 150w hps (20in away). as of now they are being fed just ph'd water (5.8-6.0) and the room temp is roughly 80 degrees. they are exactly three days from seed and now seem to be getting little white spots which almost looks like salt water was dripped on them?? has anyone encounterd this before or have any suggestions. any and all comments/tips greatly apprecitaed. thanks in advance,
