Persistent nutrient burn or deficiency?

Some background

I posted pictures not long ago and the overwhelming response was I had nutrient burn.

I did read the sticky post "read this first" but all the pictures are blank for me. So it didn't quite help as much as it should.

My setup

I'm running a 90w ufo LED in a decent size cabinet. I also have a few 23w CFL's on the side of the cabinet for supplemental lighting. I don't have much ventilation just yet, though I am running a good size oscillating fan through the back of the cab. It keep it relatively cool in there (not monitoring temps yet unfortunately). I would say it's cooler in there than in my last cabs which always turned out well.

I'm using FFOF. The babies have been in the soil for almost 5 weeks, although at about week 2-3 I used some more FFOF to bury the stems further in the container. Also once in week 2-3 I watered with some guano company super tea, which I was told (says right on the package) will not burn seedlings. I water with pH tap water (left sit in an open container for 24hours).

After getting a report of nute burn, I went out and bought 10 gallons of distilled water. I flushed with about 3x the volume of the container (they're 0.5 gallons, so about 1.5 gallons).

I don't know what else I should tell you guys, so here are the pictures.







If you need more information, I'd be more than happy to give it to you.

Thanks in advance.
 
No expert by any means, but I've been having alot of issues with my plants. Do you have a PH for the soil? Seems like that would be the first place to start

The new growth seems to be yellowing too, so that would tell me that maybe the PH is off somewhat, or you may have a lockout. What kind of soil is that? Looks kinda woody.

I don't have an exact pH, but I water with 6.3-6.8pH water each time. I should probably catch some run off this next water and see what comes out the other side.

The soil is Fox Farm Ocean Forest.

I only used the tea once, at around week 2. I flushed last week, should it have started correcting nute burn by now? FFOF shouldn't really have enough nutes to keep going for 5 weeks could it? Even though I re-added soil, I would think that if more than half of the soil is 5 weeks old it shouldn't be hot enough to burn.

I could be wrong though.

Thanks everyone

Whelp...

My pH run-off is around 5... :(

Can I raise my pH by watering with high pH'd water, instead of around neutral? or do I have to use something like lime?

Lime or ph up to 7.3
somewhere in that range ,
if you top fed,,,your soil is probly hot !
You just want your run off 6.5- ish range
then watch new growth
