Ppm rise i give up!

So I have been growing 38 plants in 4" rockwool, on top of a co co mat in hydroton, under one 1000 watt hps on a light track. I am in week 6 of flowering.

My ppm has been rising the whole time. I raised the height of my floods, I added a cover to my reservoir, and none of that has seemed to work. I also have a small thrip problem. My roots look fine.

I am using botanicare's organic nutes, humboldt county products, and some advanced nutrients.

I am up to around 700 ppm in week 6! I have some leaf curl and my plants are not in perfect health. My ppms have not dropped at all, it's like my plants never feed and I am always adding water. I have flushed my plants with clearex about three-four times now.

My buds continue to grow and are getting decently danky, but I am sure they would be bigger if they took in more nutrients?

Any other suggestions? I can't afford a crappy harvest.

Am I just screwed and should I just wait it out? It is a 8-9 week Indica. . . . . .

700 Ppm's seems a bit low for week 6. At week 6 I mix my nutrient to be around 1000. At week 7 I'm at 800 and for the final week I'm at 300. I guess it all depends on what kind of nutrients your using.
I'm wondering how big your resevoir is for those 32 plants? That might be the reason. If I had 32 plants I would probably be using 4 resevoirs feeding 8 plants each. Or 2 - 55 gallon drums feeding 16 plants each.
Plus how often do you change your nutrient?
This is my feeding scedule:
Week 1 - 800 Ppm's
Week 2 - 1000 Ppm's
Week 3,4 - 1200 Ppm's
Week 5,6 - 1000 Ppm's
Week 7 - 800 Ppm's
Week 8 - 300 Ppm's

My low ppm is exactly my point. How can I increase the nutrients when it's always on the rise? I am using a 50 gal reservoir which is more then enough water to flood the table. The longest I have gone without changing it is two weeks, but I have to add fresh RO water all the time to keep the ppms from rising. After one week I take at least 10% of the water out and add fresh nutrients or h20. Should I just raise my nutes anyways? I usually will change it every week and I have flushed about 3-4 times already with clearex . . . . .



The biggest plants is under three feet tall and they are not too bushy, mostly main colas . . . .

there just drinking what they want,u cant make them eat more....what strain is it?.and what lights?? also temp/RH???

damnet eat more you stubborn plants! Temp today was 77 and humidity at a gay 65%
Could it be my high humidity?

As far as the strain goes I have no clue. I got the seeds from a friend who got them from Cali.

All I know is the buds grow dense, smell really, really, really, strong like a skunk, and grow a lot of trichomes, almost white looking. I am pretty damn sure it's bred for the outdoors . . . . .

It's wierd though, cause my buddy is growing the same strain and is feeding more? We are using the same base nutrients, but I am using flower enhancers. I am using a co co, rock wool, and hydroton and he is just using hydroton.
I also vegged my plants longer then he did.

My lighting is one 1000 watt hps on a light track.

hows ur buddy growing his??-set up?...if its satvia its said that they dont like too much nutes,and i think plants use more water during flowering..

He has 80 clones/1week veg mix in hydoton ebb and flow under two 600 watters. I am growing with one 1000 watt on a light track with 38 plants around 3-4 weeks veg (bush master kept their height in check) with a co co mat, rock wool, and hydroton. We are both using Botanicare's pureblend series. I am using the whole series and a few other flower enhnacers (small amounts) while he is just using the base nutrients.

We are both growing in a 4' x 6' table. My plants are a lot more crowded then his, so my lower branches are not getting adequete light. He has main colas vs the majority of mine have a few branches.

Last week I looked at his and my buds were actually fatter and danker looking but his plants looks healthier.

It is for sure Indica dominant. The buds are small and hard as a rock. I have noticed sativa buds are a lot more fluffy.
