Medium is coco 2 gal smart pots. Just watered with 600 ppm solution once I seen it start to form pots were not fully dry. Seems like they take awhile to dry like 5 or 6 days. All the growth is starting to fade in a yellowish green. I believe this was caused from lack of food and possible over watering. How long should it take them to bounce back I was wanting to put into. flower but gonna wait till they get green and healthy looking again

over watering kills more plants than anything. let the upper layer of the soil get dry and then water. don't go by time as many factors affect how long it takes for the soil to dry. next grow possibly use a lighter potting mixture.

definitely give it a feeding. I'd also give them some Epsom salt by soil and foliar if possible. that would green it up more quickly. GL

cal/mag also works great
 
I have been feeding cns 17 grow as my base nutrient. I just gave them 670 ppm the other day of cns 17 hydrogaurd fulvex and a little drip CleaN. The runoff ph was were it should be so we're the ppms so I'm positive it's not lock out from salt build up or ph. I just gave them the full dose yesterday so it might take them a few days to start to green up. I don't know what the problem is unless it's just lack of food

Its been mentioned already but you need to supplement some magnesium along with your cns17, it alone probably doesn't have enough magnesium. As far as over-watering goes, I find its hard to do in coco from my own experience, but thats just me. I believe you could feed them a little stronger with a little magnesium supplement.

looking at the first pic back left hand plant i'm gunna have to ask what are ur temps also how close are the bulbs
 
My temps are fine. Light it 1000 watt mh. It's at least 2 ft away fulvex has magnesium in it 1.0% I originally thought it was root aphids but I haven't been able to spot any.
 
Botanicare makes a good cal-mag. I use it with the pure blend pro line. Since your using cns I would start using this
 
Coco gives off or leaches out potassium. Potassium can directly effect magnesium uptake. One of the main reasons they say you have to add more magnesium when growing in coco. 1% in the fulvex ain't shit and I think cns17 is what 1.5%? Might work in another medium but coco can give you magnesium trouble.[/QUOTE]
 
yea cns 17 has 3% calcium and .5% magnesium. Calmag has 3.2 % calcium 1.2% magnesium. I have calmag but I'm not sure I need all that excess calcium. what's a good dose of epsom salt per gal. 5ml or teaspoon?
 
Did you say you're watering every 6 days? You should water daily in coco. I have a plant in a 10 gallon container with coco right now that I HAVE to water with 3 gallons a day. It's a hydroponic medium that breaths exceptionally well and letting your coco get dry just screws up your pH and certain nutrient availability. I suspect this is part of your problem. Coco also demands a lot of magnesium. Epsom salts are a decent source for straight magnesium.
 
Man you gotta be feeding plants in coco EVERY TIME YOU WATER. They are yellow because you havent been feeding them enough. The smaller the plant the less nutrients you need to add but still every time you water there better be food in there. And calmag wouldnt hurt either most likely. Start feeding it, it will get better.
 
agree with alienwidow. maybe change ferts. I suspect dynagrow 7-9-5 could fix this for you right away. has close to everything needed.
 
I have some foliage pro I might give a shot I'm thinking about switching over to canna nutes I've had good success with cns 17 but this stuff is like paint And it might not be getting mixed thoroughly cns 17 is pretty low ppm tho for how much u mix. 20 ml a gal gets me at about 600 ppm o have these for epsom salts
