Hi, check out my trainwreck (pic below), @ 16 days from seed!!! no jokes.
this only being my second grow pretty chuffed so far, just hoping it stays that way.

I started the seeds on formulex with ro water at a ph of 6
once germed and grown literally just 4 leafs (excuse my terminology its been quite a while) i transfered them straight into flood & drain hydros with a ppm of 10 and ph of 5.7. within just 4 days in hydros they seemed to be florishing quickly so i up'd the ppm to 12,000 and ph down to 5.5. now 16 days from seed ive now up'd the ppm to 15,000 and got the ph stable at 5.2. no signs of any nutrient burn what so ever and is it just me or are most of them huge for just 16 days from seed? another 5 days and ill up it to 18,000 ppm

Equiptment

esoteric hydropod flood n drain
2x400 hps in cool tubes
5" silenced ducting, fan, silencer, 6" huge carbon filter with 5" reducer,
