i actually think your problem is root rot from too much water, not enough air. ive had similar problems. now i make sure the roots have six inches of air from netpot to water. the pot stays dry and the plant gets what it needs. Check your roots. are they brown? If so, foliar feed them, cut your...

ive had a hermie polinate several varietals i had in my room. all the subesequent seeds were feminized. Hermies are great!

nute burn. lower your concentration of ferts. flush with water, repot in a larger container to give the roots some room to grow so it can get bigger.

what kind of nutes are you using? you should try keeping the ferts at about 400ppm for a while. make sure your ph balancing your solution....5.5 I cant imagine what the problem is...do you let your roots dry out sufficiently? I just use a dwc. I let the roots hang in water with bubblers and make...

it all depends on so many factors. You need to fertilize them though, if even just foliarly. Phosphoric acid is often used to lower ph. you need to invest in a ph meter. , or get a simple ph fish drip test ($5 at petco) Ive used vinegar before too.

check for fast moving larvae like critters. They are called thrips. you will notice they move quickly on the bottom of the leaves. they leave a shiny film on top of the leaves and attack the veins, which is probably why they are turning brown. Spider mites will not do that. you know you have...

if the leaves are just slightly browned, and yellowed and only on the tips, and they curl down slightly it was an overnute problem. This is a good indicator that your feeding them just about the right amount of nutes. Just cut back a bit and keep feeding them normally. Flushing is always good...

your problem is your soil. it needs to be mixed with draining materials like sand. the leaves are turning yellow because the roots are rotting and the plant cant take any nutes at all. it really doesnt matter what you feed them at this point, they have no way of taking up food. They are probably...

let them go from completely soaked to almost completely dry. These are weeds. They will like the fluctuation and it gives them time to recoup. I would recommend changing your soil to coco or at least some compost/dirt/sand mix. I dont like having those white chunks of fertilizer. they burn the...

could be burn from foliar spraying, or if you are overnuting them they will burn like that. Ph test your solution, make sure your only using 1/4 nutes, add a couple drops of superthrive and they should be ok. That is not bug damage. are you foliar spraying? Try lowering your concentration. I had...

make sure your tanks are completely blacked out to keep light from growing algae, which will take the o2 out of the water and promote other problems. I use construction plastic, or white/black 7 mil plastic. Make sure the outside is wrapped in a reflective material though, so the light doesnt...

you may be overwatering, though you would think it is hard to do. You will know if you are overwatering in a hydro setup if your roots begin to turn brown and die at an abnormal rate. The first sign you will see in the leaves is yellowing older fan leaves and dying lower leaves, as the plant...

CANNA nutrients are the shit. they come in two part solutions for growth, and two for bloom. Also check out rhizotonic, which is great for root development. invest in a PH meter and keep them at 5.5 Ive used lots of nutes, but canna is the best.

sounds like your tank is too small. 2 gal? I use 25 gal rubbermaids for 2-3 plants so each has sufficient water so ph and ppm does not fluctuate too much. The most important thing ive found about dwc is letting the roots get plenty of air. The water level should always be 6" below the netpots...

try using canna products. ive found amazing improvements in quality from previous systems. Very easy to use, and it contains a buffering agent so the PH is much more stable. Once I adjust the PH, it only requires attention every 48 hours or so. This of course depends on your resevoir system, but...
