New Grower HELP - AN Coco Coir - Start of nutrient burn or something else more serious?

Hello everyone!

Today, my plant is 22 days old since it sprouted. It's a bag seed of an unknown strain, hoping for a female of course. :lol: I'm currently using some Botanicare Coco Coir w/ Advanced Nutrients pH Perfect Technology Sensi Coco Grow A&B @ 140 PPM. This pH's my R/O water to 6.2 according to my pH meter (not calibrated yet). My current runoff is around 130 PPM w/ pH @ 6.4. I have an iPower 600W MH Air Cooled Hood at about 18" away from the top of the plant.

Temperatures range from 79°F - 86°F throughout the day. Running a 20/4 light schedule. Humidity ranges from 50% - 60%. I'm planning on keeping it in the veg stage for 7 - 8 weeks.

I started feeding since I planted the seed at a VERY low dosage in tap water which runs @ 180 PPM just so the pH perfect technology pH'd my water since that is the only way I can adjust my pH.. According to my pH meter it wasn't doing much since it was such a low amount of nutes. This made me up the PPMs a little too high because I'm a noob. Wasn't being careful & was running the nutrient mix at 300, then 450, then 600 PPM (w/ tap @ 180 PPM though) way too early and noticed some brown/yellowing tips, and holes in some leaves. Since then I switch to R/O water and lowered the mix to 140 PPM and I've been using that for the past 3 days now.

Just looking for some good advice on what to do to help & is this plant looking any good? Is this just some nute burn or something I should worry about? I'll have some pictures below:

(Looks to me in this one that the leaves are canoeing upwards a little? Maybe not, I don't have the trained eye for this yet. Also, there looks to be a little bit of yellowing on the leaf blades. Newer Growth)

(Same leaf, burnt yellow tip. Very slight yellowing on leaf.)

(Attempted to FIM plant a couple days ago)

(Can see more burning of the leaf edges of this lower leaf, & a better view of what looks to be some canoeing upward up top.)

(This leaf has some yellow spotting/burning)

(This leaf is kind of weird, isn't looking THAT bad, but has a blade that grew tucking inward. I don't know what that's all about)

(This lower growth has yellowing on edges with burnt holes.)

(This first true set of leaf is somewhat withering away at the tip. Also a look at some inner growth)

(Inner growth look any better?)

Once again just looking for some good advice from experienced people that can help keep this plant looking healthy. Much is appreciated, THANK YOU!

Great pictures...I think the pot could be better,one that is bigger at the base.I use protek and botanicare cal/mag along with GH flora,grow,micro,bloom mix.All in 7 gallon smart pots sittin in the green house,all plants look great.The larger pots allow for wet/dry periods between watering.

Well I was hoping I could keep it in the 1 gallon until it at least preflowers so I can find out whether it's a male or female. I don't want to transplant into the 5 gallon and have to waste all the extra water & nutes if it turns out male.. BUT, the roots are already poking out of the bottom (the root system establishes quite a bit in a coco hydro grow) So should I just transplant into the 5 gallon now?
 
Looks like light burn, and over watering with to high ph. Did u water right b4 u took the pics? Definitely calibrate ur ph meter, no point in using it if you don't. Flush with 1/4 nute solution and water ph'd @5.8. and let it dry out completely b4 watering again cannabis like the wet dry cycle.

Sure up plant now...it can only help correct the condition of the soil.I also remove all ugly leaf/damaged leaf.

Yes these pictures were taken right after watering.
