GH Water Farm

did as you said and upped the times that the plants were being watered. Now my leaves are starting to curl sideways and some are beginning to get dark points on the new growth. too much water, right? what about the leaves curling so strangely?

The only way to over water with a waterfarm is fill the resevior up past the hydroton (and that's just a guess as I've never tried it), you only add water to the white water line on the blue drain tube.

If you don't run the pumps 24/7 then that's your problem. You seem dead set on using the waterfarm incorrectly, and if so it probably won't work properly.

I've had 3 grows (with a wf), and I'm on my 4th now and have never had the air pumps off, and the only problems i've ever had were created by me (nute burn, deficencies, pH etc.).

This isnt even remotely like growing in soil, you cannot over water if you use the wf properly. Besides the fact that once your roots hit the water in the resevior, those roots are now in DWC (Deep Water Culture) and if you don't aerate that water, by running the air pumps, you may be drowning them, I don't know the answer to that. Before the roots hit the resevior its an aerated drip, so some of your roots will always get aerated drip, while others get dwc.

So if there is a problem, then it's with you and how your running your set up, nutes, turning off the pumps or whatever your doing diffently.

I've never had dark spots at the leaf tips, nute burn at tips but that is lighter (a pic would help diagnose your issue) but depending on which way the leaves are curling it could be heat stress, nute deficiency or something else.

I would suggest you use the wf as it's intended.

P.S edited to add, I hope you bought a better air pump because the one that comes with the waterfarm is a POS, as well as drilling dozens more holes in the pot portion of the wf.

This will be my last attempt to explain it, hopefully you understand,

You obviously come from a soil growing backround, since your so concerned about over watering. The medium in a soil grow is soil, the medium in hydro is water.

You would'nt pull your plants roots out of the soil (it's medium) during a grow, would you? Well you don't in a waterfarm either.

Keep your air pump going 24/7 for the duration of your grow.

Get a better air pump.

Run an airstone in the rez 24/7.

Drill more holes in your waterfarm pot, to allow for more and better dispersed root growth.

Check your pH and nutes everyday.

Read as much as you can on here and other informative websites, like national cannagraphic, grasscity and 420.com, and learn about what your doing, which will make you a better grower.

If you do these things you will be rewarded with a faster grow, more weight and basically a better end product.

The choice is yours bud.

Thank man.....appreciate the insight.....I'm a soil grower converting so my mind set has to change.....I did get an airstone in there 24/7 and am checking my ph daily......got new air pumps, etc.....will drill more holes in the holder next plant....

the only thing I guess that is different in mine than yours is that my clones are rooted in 2" rockwool cubes and they retain water. yours are seedlings straight in the medium and has nothing to hold water.....I'm simply trying to 'adjust' for that variable.....I don't do seeds, I clone cuttings....

Thanks again for your help.....peace

Here, I just typed into the search bar at top waterfarm rockwool, and found 13 pages of threads that contain info on both. Here's a few to get you started.
