Personally, the reason I use ppm counts is to track the strengh of the nute solution. I don't see it any different than saying that you are using 1/4, 1/2, 3/4 or full strength. And yes, this ppm count habit that ive fallen into was something that I kept from my years of hydro growing..... It's just a different method of tracking your nute solution is all......
Cool. Some folks are a bit over-zealous with the necessity for ultra-pure water. But isn't the ppm guide usually related to hydro grows, or do you need to alter it for soil quantities? In other words...does it take you the same quantity of nutrients to get the same hydro ppm's as (let's say) a 1 tsp per gallon recommendation for soil?
The ppm guide is for sure a hydro necessity. I, like you said, "morphed" this over into my soil nute regimen. No, I don't alter the ppm's from a usual hydro application specifically for soil. Just like I would hydro, I start off with light nutes and work up as the plant(s) grow.Quote:

I track ppm's just so I know I'm not over feeding.
I was using the numbers compatitively. Rephrased: If it takes 1 tsp per gallon to get to your hydro ppm goal, is 1 tsp per gallon used in soil also? You answered already, but I am wondering the advantage of using a meter rather than a cheap teaspoon. But if it's a habit, I think I understand, lol. Being in soil all my life, teaspoons are a necessity.
I have what looks like the same problem and am also using Fox Farm.
Hi guys I am having a similar problem, I am using a 250w mh/hps switchable using FFOF I am using florilux nutes (B.C. grow ect) my water ph is about 6.5 and same with nutes. I was using my tap water but had to change to spring water because my water has a ph of like 9. I have been using spring water for about a week. Temps are about 75 day 70 nite. I\\\'m getting a leaf problem first the leaves look dry then they start to get some brown spots. It ends up just spreading and the whole leaf curls turns brown and yellow. I can post some pics if anyone could give me a reply. I have some plants that are doing this and some have been fed with nutes and some have not. Can a lack of something in the air like lack of co2 thats could do this or even too much co2 because my rooms in the basement with the furnace. Some one please help me. I had filled out the full trouble shooting form under another post under leaves curling yellow brown spots please help me :( so someone please help me first time grower :) If you need more info just ask I have tried about everything that people have suggested. thanx in advance for the help
c.strife-
Read the beginning of the thread where I was told to copy and paste. Fill that out so you can get help 2.
I will keep updating once in awhile on my own grow. Just got the grow bible so I think that will help as well. Thanks again guys-
Greetings.
Your pics look like overfert. Very dark green in some areas, which probably indicates to much N. I don't think it's the quality of water necessarily, but r/o should be good to use. Distilled water is also good to use. With all the fert you put in there, it should be enough for a while without any more added. The problem with these liquid ferts is that while the company will give instructions on the back as to how much to mix with water, they don't tell you how often to feed. I know there are feeding schedules but when problems like this develop, you've got to wonder just how accurate these schedules are. Foxfarm makes powder ferts that come in boxes that solves this problem. Make sure you read labels on back of the container and see what ferts are in there. Plants usually need 11 to 16 different fert components to grow and ideally you fert with a product that has as much as possible. Just not too often, eh?
Regarding the teaspoon and ppm/tds discussion, I would think they're essentially the same, but a meter allows for a more precise measurement and will help a grower understand fert content per unit of water when the two are mixed together.
4 Weeks. How's she look?
Show off. :thumbsup: Looks great. However, need white light, not sodium to see it properly and a close up of some leaves would be great to see how they look individually.
