Nute Burn?

She's a 3 weeks old and I started her on 15% technaflora boost + grow + the rest of the starter nutes. I'm noticing some yellowing tips, edges curling up a bit & even a few small brown spots on the edge. She's still putting out new growth though, and getting taller each day. Is this something I should be worried about?

It's more than nute burn, is your pH in proper range? I would definitely be thinking about it, it's likely to progress...

I keep the PH right around 6.0. minimum of about 5.8 and max of 6.1 and change. I calibrate my meter every few days so I think that's pretty accurate. TDS is right around 450 - 350 of which is due to my hard water. Only about 100 PPM of nutes. I'm on an Ebb & Flow schedule of 15 minutes every 4 hours.

Nute temp is right at 70 consistently. Ambient air temp is around 72-75 and drops to about 65 while the lights are off.

Ugh, I hope it doesn't progress. She was doing so well!

I've also been top-watering this one with plain PH'ed water, 6.0, thinking it may flush her out if the nutes are causing problems. Twice per day.

Could it be TMV? I do smoke tobacco in the adjacent room, but they're in a tent with highly circulated air. I've seen some posts about TMV and it's got me worried.

I'm not familiar with your nutes but 100 ppm isn't much for a plant that size. I thinking your under feeding it and that's the problem! I would be give it 400-500 ppm's at least!

Interesting... I'll try adding a bit more nute to see what happens. So, my filtered tap water starts at 350 PPM. If I add 200 PPM of nute it will put me at 550 - will that be OK? My only concern is I have one that's really doing well and is completely green. I don't want to take it in the wrong direction and mess her up, too.
