am I using the right amount of nutes for my mom plant...

in rock wool.

I use the general hydroponics 3 part solution.

I use a 32 gallon trash can with 68 degree water, 100 PPM.

24 teaspons Grow
16 Teaspoons micro
8 teasponns bloom

the plant is looking sort of rough, a few leafs dieing off, browing/yellowing etc..

Have any pictures?

Pics for sure, sounds like it could be nute lock. So hard to tell with such little info. The mix you're using should be good for your veg cycle.

How big is this mother? You're ppm should be more like 900. This does not include the ppm of your water. You have to measeure that, and subtract it from your reading. I like 900 ppm of nutes, and have it 1200 because my water is 300.

Make up a new batch of nutes, in phd water, if your using tap water ph it, then let it sit for 36 hours then test ph and adjust.
then empty the res, flush and clean with 80/20 water/bleach. Now your plants will be getting an "air bath" which can produce kickass growth in days following.
Get a spray bottle and fill with some of your nute solution. Shake it to create airbubbles and really mixing the nutes - lift up res lid and spray the roots of your plants liberally, give them about 2 - 3 mins then refill your res.

Should give your mom a good kick in the but..

Good luck bud

the mom is huge, 4-5 foot tall, 3 or 4 feet wide, cant even fit my hands around the stalk.

I am thinking it may have to do with the temps, about 83-88 24 hour a day light.

I will try and get pics.

plants will grow at that heat bro

here ya go.

As mentioned probably not the heat. If your lamp is to close you could be cooking them up a little.The that I can see it seems to be the mid to upper affected. If I had to guess I would lean towards nute burn or lock out. What are your roots and ph like? Also maybe she'd like a little more food. 100ppm seems a little low imo.

100pm is the ppm of the tap water I use. The PPM is higher when I mix the nutes in. How important is it to let the tap water dechlorinate? I usually just use the water directly out of the tap, without it sitting over night. My PH is 6.0-6.5

whats your PPM with the nutes? that is the important number. $10 says lock out.

I made an investment on an ro, so I can't really say. If you have an extra 100 or so check out ebay seller purewater club. Pretty sure thats the name, I grabbed a 100gpd, 6 stage di. I think that there maybe others chems than chlorine in you water. Not to say that there aren't people having success with tap water, just was able to fit it in my budget so I did.http://www.ewg.org/tap-water/welcome Try this link to have an idea of what you're dealing with.
