I have three plants currently growing under a 600 watt hps, 2 seedsman white widow and 1 dina fem critical +. they're 34 days old from seed. I started noticing last week that the bottom leaves were starting to get brown spots and they were very brittle. The temps in my tent stay under 80 and I'm only feeding them half strength nutes. Has anyone seen this before any info would help. The lights come on in 15 minutes some I'll post some pics soon.

I just fed them yesterday so I'll have to wait a while to try that. I am feeding them with grow big and big bloom every other water which is every 4-5 days,depending how dry the soil is.

Have you tried giving them a good flush? Nutrient lock out will present the same as a nutrient deficiency, but adding more nutes will only worsen the issue.

Haven't tried that yet. I transplanted them 8 days ago 1 into a 5 gallon bag and the other into a 3 gallon bag.

Its completely possible they got locked out, I'm not saying it is the problem, but its often something safe to try that can make a big difference.

Honestly you can do a flush at any time as long as your soil has drainage. The flush process should wick air into the root zone again as long as you have drainage and aren't gonna leave them in a swamp.

So should I flush them today? And is it ok to do it with regular tap water in the tub?

You want to flush with clean PH'd water and in the tub works just fine. You want to flush 2 times the volume of the pot they are in. So 3 gallon pot flush with 5-6 gallons of water.
