anything but water + vitamins = nute burn. seeds needs a chance to build the root system before then can successfully take up nutrients. usually till the first set of "true leaves" (personally all i use is superthrive and water till the 2nd set is just about done.

first off they are too young for a HID bulb. get a fluro on them. you can tell you have a highpressure sodium bulb there with those black lines

I just learned this the hard way... they're all pretty much right. Take it "slow and low" with nutes, especially with seedlings.

+1 rep if this helps?

I tend to wait until I start to see signs of nutrient deficiency before I feed to avoid burning (you can always add more, but you can't take out). That being said, using the GH Flora Series and following their schedule, I have never had a problem with nutes.

when i sprouted mine, it was a while before i added nutrients. about 2 weeks maybe. My water is usually a little over 100ppm and the first dose i did totaled around 200-300 ppm. the following week when i changed water, i went up to 600ppm. The past week they've been at about 700-800ppm. Mine grow pretty quickly though. They have been under a 400W MH from the day i planted them in rockwool.

I hope this can at least answer a little about your nutrient questions, even though i'm using flood+drain.

see my thread here.

Bro you said you have drip system right? maybe the timing if off maybe you need to have water running more often? im not too familiar with drip systems but I run DWC and when I first started i didnt put enought water in the res and my plants looked exactly like yours until the roots found there way to the bottom of the netpot into the res water if that means anything? so basically im saying you might need more water lol
