Heres the rundown I am growing in FFOF soil, 20/4, 150watt hps with 2 23 watt cfl, water every 2-3 days, but I recently attempted to flush them so they are definitly overwatered currently. I used a very small amount of big bloom with my last watering, the ph is around 7.8 I am trying to get it down by using API ph down.

Now to the problem the plant is porbable 16 days old from seed and it has severe yellowing on the first leaves with lots of purple in the middle and edges. The next set are green but I can tell its starting to glaze over. The stem is also red.

stop using the big bloom for now.
That FF OF is naturally hot i believe for seedlings. Best if used for transplanting into bigger pots with bigger plants. Your plants are burnt man, you need to get that soil flushed after it dries out a bit.
How high is the light from it? You should really only use flouro's for seedlings, unless you keep the light far away. But then you'll have stretching. Use the Flouro's you have for this part.
Save the HID for later.

The plants definitely arent being burnt by the light I have two other plants one which is growing very fast and another thats doing ok. This one is the only one thats hurting right now. I only used 1 tsp for a 1 gal container of water and I havent seen any change good or bad from it so far.
