Whats your water source? Whats the ph of your water? How much of the AN are you feeding? Little CalMag probably wouldn't hurt.

On another note, welcome to RIU!
 
Hey
My water source is tap water
The ph of my water is between 6.0-6.5
And I'm using the advanced nutrient ph perfect series.
I'm feeding them 1ml per liter every 3 days in 20 liter pots.

Thanks for the help
 
Well I haven't used coco but the couple people I know who run coco tend to keep ph closer to 5.6-5.8, if you were in soil that ph would be awesome, but might be something to research/consider. The only other thing is I know when I have use tap water, I let it sit in an open container for 48-72 hours because most city add things such as chlorine to the water, which buy doing this allows the cool evaporate out of the tap water.

Definitely don't think the nutrients are the problem here, but I might consider giving it boost in the CalMag department. It appears from photos that you have a little bit of leaf curl beginning which can often be a sign of a CalMag deficiency.

My only concern about the nutes is the once every 3 days watering. There again, not familiar with coco first hand, but My plants get water maybe every 5-7 days however I grow and soil and let it get pretty dry before adding more water.

Granted it is a Plant Issue, but you may also want to throw a post into Newbie Central as that forum seems to get a lot of comments, just a thought, wouldn't hurt anything at least.
 
Week 4
The thing is that the coco ph is around 6.5
My tap water ph is around 7 when I put the nutrition they get to 6.3 and then I water my plants.
The ph of the runoff water is 6.2

The thing is throughout the all vegetative grow I did the same actions and everything went perfect.

So I don't understand
 
Are you letting your tap water sit for a couple days? Im using coco week 2 flower i ph wayer to 6 then add nutes. No problems so far
 
Tap water has chlorine in it from what ive read up you need to let it sit 24-72 hours some say. i leave mine for about a day sometimes over. But if this was the problem its weird that its only showing now imo.

You wouldn't think it would make that big of a difference, however plants tend to drink/eat considerably more during flower then in veg. Couple things you can do, as its been stated couple times is let the water sit out, I person goi 48-72 hours. Next thing you can do is contact the city you live in or check out their website to access the water report to gain a little bit better idea of what your actually dealing with coming out of your faucet. Finally, I would if nothing else give it some CalMag personally, however thats just my opinion. Haven't used AN myself, so could need more food, but I'd be very leary there.
 
I really never put much thought into it. I have tested after ice added nutes but its not made much difference. I hand feed in small amounts and dont use many nutes

@TubePot hit the nail on the head. When ever you add something to your water it will cause the ph to fluctuate. I have had my ph drop in a gallon of water from 6.8 down to 6.1 by adding 3ml of nutes. Thats a pretty big swing.

I heard Rhixotonic etc messes with ph, im only using Big Bud and Bud Cany i just tested again and its droped 0.1 since i tested before i added a couple hours ago, but hey thats what im here for to listen and learn ill start doing it the other way around from now on.
 
Greetings wiha
Airiate the water as well, it helps get rid of the chlorine and stuff also give's oxygen to the roots, they like that.

One thing I wanted to add, but totally off topic. I usually mention this in my welcome to RIU, but for whatever reason completely spaced it.

Many members on her are more then happy to give advice based on opinions and experience, however ever grow is different and it boils down to you finding what works best for you and your garden. Before taking someones word as gospel from here or any other site I recommend doing research to try and verify the information. Personally, when someone makes suggestions I like to have additional evidence, whether it be photos in there journals, videos, or additional outside sources.

Also, keep in mind that just because someone has a "Well-Known Member" status, doesn't really mean much. Many new members assume "Well-Known" = "Experienced Grower" however, I am a perfect example a new grower with this status as it is more so based off your involvement on the forum.

Again, welcome to RIU and best of luck with your grows!
 
It's a ph issue get rid of the perlite next time and use straight coco and use a ph range 5.5-6.2 never let the coco go completely dry
