Your soil starts with:
100-250 mg/l N
100-250 mg/l P
150-350 mg/l K.
Even though that isn't very much at all, You may have started nutes too early.
That's really all I can think of.
Or it's your water.
100-250 mg/l N
100-250 mg/l P
150-350 mg/l K.

... that's not nute burn, it would show on nearly all the tips, especially at the tops.... likely underfed, long tern,.. 1ml is very weak dosing.... Oh, that RH%, you're sure on that? It's waaaay too low, this can cause stress and stunting on younger plants,.... tip browning is fairly generic symptom for several possible issues,....

well, the low RH% forces the seedling to work like hell to move water and keep up with the over-rapid transpiration rates,.. nutes can get dragged along and that can overwhelm the plant as well, too much accumulating and not getting utilized in time,.. this can in turn mimic nute burn symptoms,...
it's more complex than this, so look up the vapor pressure deficit (VPD) article in the Reference section to see what I mean,...

Hey mate,
Don't trust so much in my opinion, I'm currently on my first grow, so I'm a noob still learning on the job.
But you probably have an issue with your RH. I've tried to keep mine between 55-70% during the first two weeks. On day 14 I gave a small feed of 1ml cal mag, 1ml silic boost and 0,5ml of standard npk (6-2-4) per liter. All the watering was tap water. I don't have ph meter.
I haven't fed again, I'm growing an auto in soil with npk basis and I don't see any nute deficiency so far.
I have a 600w led (136 actual watts) and I keep it around 18-20". She's growing shorty and bushy with short internodes and I'm loving it.
These pictures are from yesterday, day 17.
Hope you don't mind my noob opinion.

Is that where you always take your humidity readings from? With the meter right on the soil surface? That might be tricking you into thinking your humidity is higher than it really is. Just something I noticed in your pics and nobody else pointed out. Not sure if it has to do with the sick looking plant or not though.
