:lol:


Can we get a little more info on your setup? Sounds like possibly nutrient burn, but it could be 1000 different things without knowing.

Ok, my fruits are definately not reaching their full potential.  The problem seems to start with a mild browning at the end of the leaves and the fruits are stringy and not dense.  I get six ounces of dried material that looks unimpressive off of a 600 watt H.P.S.


1. Are you growing from seed or clones?

Clones.

2. How old are your plants?

About eight weeks.

3. How tall are your plants?

About 18 inches.

4. What type of hydro system are you using?

Ebb and flow.

5. What brand/type of nutrients are you using?

Flora Nova.

6. What is the Ph of your nutrient solution?

5.8


7. What is the PPM/EC of your tap water?

About 250 ppm.

8. What is the PPM/EC of your nutrient solution?

About 1450 ppm.

9. What is the temperature of your nutrient solution?

About 75 degrees.

10. Does your PPM/EC show a rise or fall when you do your daily PPM check?

I've seen it do both.

11. Does your pH show a rise or fall when you do your daily check?

Neither.  It is a very expensive and precise meter that sticks on one reading.

12. Do you foliar feed or spray your plants with anything?

No.

13. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")

600 watt H.P.S. with expensive Son Agro "full-spectrum" bulb.

14. How close are your lights to the plants?

About six inches.  My hood is air-cooled by being vented.

15. What size is your grow space in square feet?

My table is 36 in. x 36 in.  My space is an entire room about 10 x 15 feet.


16. What is the temperature and humidity in your grow space?

Varies.  Usually about 80.  Humidity the same as outside (temperate deciduous climate).

17. Have you noticed any insect activity in your grow space?

No.

18. How much experience do you have growing?

A decent amount.

Your water is super hard, most of that 250ppm will be in the form of Calcium then to run another 1200ppm seems like A LOT. Using synthetic hydro nutes I typically don't want to go over 1300ppm regardless of strain and often times I cut it down to 1000-1150ppm this is using RO or distilled water with ~10ppm so I know exactly what's in my mix. With any strain I'd be very careful exceeding 1300ppm with Floranova when knowing exactly what my plants are getting.

Do you have pictures ?

No, I do not have a digital camera.

I was very careful not to go over 1,600 ppm with this batch (whereas I have not been so nazi-like on my last batches).  So, you are saying that if I carefully add water and nutrients throughout the fruiting cycle and keep my ppm at about 1,100 then things will end up better?  I am set to harvest in three days and this batch is a lost cause.  The stringy buds (if you can call them that) are worthless. 

This is utterly frustrating.  I don't think plants like me.  :shrug:  I think I'm just going to go back to soil.  It requires nothing except watering them once a week.

1450-1600 PPM is a lot especially when you don't know what exactly is found in your water. A lot of your tap water's 250ppm is calcium which is A LOT I'd for sure want to use a hardwater formula if my tap water was that hard. I actually would try to do anything to lower the PPM of my tap water, perhaps a brita, a column of charcoal, or anything really.

I try to stick to ~1300ppm or 2.0 EC I believe 1300ppm at the .7 conversion is 2.3 EC 1100 being over 2.0 this is also knowing my water source which varies, I've use tap water, RO, Distilled but I make sure the PPMs are low.

Well, I just ppm'ed my tap water and I got 350 this time.  It's official...I have super hard water.

I think I am going to have to haul in distilled and R.O.'ed water.  It will be a pain in the ass, but I can't keep throwing money down the toilet with nutes and rockwool and getting nothing in return.  It is going to look shady bringing in big blue Culligan containers and distilled water all of the time, but it looks like that is what I am going to have to do.

So, just to make sure: if I have low ppm water, add nutes until my solution is at about 1100 ppm, and have a PH of 5.8 will I FINALLY get a decent yield?  Is there anything else I should know or do?  Will I have to add calcium and magnesium as additives to my resevoir for example?

Grrrrr!!!  :grin:


P.S.  I have a 40 gallon resevoir.  Would it be better to do 10 gallons of my tap water (which has tons of minerals in it at 350 ppm) and then the other 30 gallons of R.O.'ed water and distilled water?  That way my ppm's would probably be about 100 and I wouldn't have to add any minerals and such...?

It sounds like you should invest in an RO filter and make the water yourself. It would pay for itself after you had to buy bottled water for a 40 gallon res a few times.

I've heard that R.O. filters take a long time to filter just one gallon.  I'd rather buy some Culligan drinking water and a bunch of gallons of distilled water than sit there all day waiting for one of those filters to spit out the appropriate amount of water.

A good RO system doesn't take much time at all to filter a gallon. I think you are thinking of the filter pitchers?

Well, keep in mind I have a 40 gallon resevoir.  How many hours of screwing around will it take to get 40 gallons of water?  I think I'd rather just buy jugs of water and save time.

I have a 240 GPD RO system. That means it could fill your entire res in just 2 hours. Honestly not too bad IMO, just turn it on, set an alarm for an hour and 55 minutes and then go watch TV or something

Quick search of a 240 gallon per day R.O. machine - $940.

Yikes.

You can exceed this, I go anywhere from 1100-1300 and sometimes higher if the strain is still hungry which isn't often. I used to slam my plants until I got signs of burn and back off but now I feed so that my plants look healthy and adjust from there.


, and have a PH of 5.8 will I FINALLY get a decent yield?  Is there anything else I should know or do?  Will I have to add calcium and magnesium as additives to my resevoir for example?

I use a pH of 5.5 and I don't think you will need cal/mag but it depends on the strain and your nutes. I run GH flora and if you need more calcium you just add a bit more micro and it works great.

As for yields, of course something else could go wrong but you seem to have a handle on things and it's just your tapwater that is the problem... but I don't know as you don't have pictures. I can say for sure if you fix your water and have lower ppms you're going to be on the right track.

also if you're bringing in your water by jugs you might want to look into top offs and seriously consider going to gh flora as it's easier to adjust your nutrient mix.

top offs are to save water and nutrients, essentially if your goal was 1300ppm when your res reaches 1000 ppm you would add back nutrients to reach 1300ppm which would depend on how much water is displaced in your reservoir. If you save the distilled water from your AC and dehumidifier this can make for a very efficient grow.

i dunno koons, when you top up like that for too long your water gets really toxic
the chelates that most of your minerals are attached to dont get absorbed by the plant, eventually the concentration of EDTA and such gets too high.

ive been using a little PUR faucet filter lately and it seems to work,
each one does 100gals and you can get 3 of them for like $40
i havent been using a PPM meter tho, but my tap water comes in around 300ppm, at least when i checked it 3 months ago...

Lugging water like that is really time consuming and back breaking work IMO.
