What is causing this?

[sourdieselyumyum]

Day 5 of flower but this has been going on since veg seems like it's slowly working its way up the plant I'm in coco coir in 2 gal smart pots feeding cns 17 bloom 600-700 ppm ph to 5.8. Runoff last few waters has actually came out lower than what I put in which Is Strange. I'm not sure if the drip clean might be the cause of that. Also the leaf veins look red. I have been treating for root aphids. Not sure if they are causing this tho as I haven't really seen anymore of the micros just flyers that look like gnats on sticky trap. Any ideas. They look fairly healthy otherwise

Are you on city water? If so, STOP phing to 5.8 don't worry about ph if you are on city water, well water is another story. It's definitely a deficiency due to ph, I repeat if you are on city water STOP phing your water. I've seen so many people jack up their plants with ph up and ph down, my friend won't listen and he always playing with the ph, his plants look like crap, I never ph my plants and they look awesome.

You don't PH in coco?

 

[sourdieselyumyum]

I'm using ro water comes out around 15 ppm

You can pH in coco but what maryjane is saying is that it isn't all that necessary. It's more necessary to give an adequate amount of fert and your fert ppm looks a little low, especially for a coco grow as there is not nutrients whatsoever in coco. It looks like you plants could use more fert and if you insist on pH'ing, then shoot more for 6.2-6.3. That's nute/water mixed, then pH. It looks like nitrogen is being pulled out of the lower leaves and used to feed the upper leaves. I think it would be good if you could transplant them all into bigger pots, but maybe this isn't necessary. Just get the fert right. coco is more like a hydro grow since there's no nutes to it. it's just something for the roots to hold on to. you could grow in just perlite too, if you wanted to try that sometime. just use the same technique as coco. at first, try the same ppm with 6.3 pH or so and see what happens. if the yellowing continues, the give more fert next watering. also, there isn't much N in cns bloom either. pH of 6.2 is good for both soil and hydro.

i agree with the pollack you should be up around 6.2-6.4

good to add calcium/mag to your ro water before you add your other nutes... a soluble cacium nitrate will give you the added nitrogen... next chelate the calcium with some amino acids!

 

[sourdieselyumyum]

Yea cns 17 bloom itself is a pretty light fert ppm wise. A full dose of bloom which is 18ml a gal only gets u around 650 ppm base nutrient. I would normally run my base around 800 ppm then add additives. You guys think it's safe to go above recommend dosage to achieve desired ppm rate. I have canna coco nutes I could switch too but I like the completeness of cns 17

 

[polishpollack]

you'll have try something and see what happens. you could consider mixing in a little canna with the cns if you want. not sure what to tell you here because botanicare makes so many bottles, it's hard to tell which ones are necessary or not.

I have used coco for 6 years or so, only time I've ever had problems was when a buddy of mine started messing with the ph demanding we needed to do it.

If you are on city water, you can drink it, it's good enough for a weed. With the correct dose of nutes in city water, you never need to ph it. It's a waste of time.

Unless you have a well, that's a diffrent story.

I use nutes one watering, then the next watering calmag and hygrozyme, nutes then calmag and Hygrozyme etc.....I never ph any of it and I never have problems.

 

[MaryJaneFamily420]

You don't PH in coco?

Nope, pointless, most city water is already the correct or nutrel PH for us. Nutes already lower it. It's a good idea to let the pH cover a range instead of always adjusting to the exact same pH number.

 

[MaryJaneFamily420]

also you don't need bloom yet, a regular veg feed til week five then start backing off veg feed and replacing it with bloom, not enough N and a low ph will make the N unavailable and locked out.

Heres a few more pics of the lower area and mid

 

[polishpollack]

usually when the lower leaves go yellow and die, it's because of low nitrogen in the soil. these plants continue to grow in flower and need some nitrogen, but perhaps what they're getting now isn't enough. not sure what to tell you other than that. it's up to you what to do, but if you give nitrogen, just go easy with it and see what happens.

Quit spreading bad information, and what you're telling the OP is bad information. You don't pH at all? Good for you, don't tell other people no to. My city water is almost 400 ppm, if you know what ppm's are, and the pH is 8.0! Needless to say I use RO water and I pH every time I mix up nutrients, not doing this is just stupid. When I use the Maxi series, after adding the measured amount of powder the pH is down in the mid 4's. You wouldn't adjust that? You'd just run it as is? You will have unhappy, or dead, plants.
You might have good city water, a lot of people don't. You might be in the right pH range when you're done adding your nutes, this depends on what nutes are used. Somebody else using different nutes will have a different results.

I'm using ro water comes out around 15 ppm

Despite what some people are telling you, keep pHing your nutes. You know as well as I that as soon as you add nutrients to RO water the pH changes quite a bit, usually going much lower. Is there any way you could be overwatering a little?

 

[sourdieselyumyum]

No way I'm over watering they are in 2 gal smart pot of coco they are dry every other day. The ph in the medium and runoff isn't that bad either. I'm gonna stop adding drip clean for a water or two and see if that has any affect when I water with 600ppm and it comes out 400 ppm that either means they are eating and there hungry or being stripped of nutrients possibly by the drip clean
