I think this plant is done

[pegboy]

Everyday leaves are getting worse and worse . It's in coca . Still dealing by the day

OK. Thats looking more and more like nutrient lock out. Have you checked PH and are you feeding with synthetic nutes or are these soil?

I've been feeding it with this . And it does seem to me that at the time I starting feeding them this that the plants started to seem off . I mix it I'm a 1gallon jug . It says 4ml per l . So I put about 15ml of each into the gallon jug and mix with water. It ph's itself to about 5.8 or so 5.9. Not sure what I'm doing wrong

Hopefully a stupid question, but your wording is a little ambiguous. Is there water in this jug BEFORE you start mixing in the nutes?

Yes the jug has water in it as I add the nutrition into the container

I haven't really used my pH Perfect so I don't have any kind of feel for it, but the full recommended dose may be on the heavy side. Are you using RO/distilled water? Are you actually measuring the pH, or just assuming the pH Perfect is doing what it's supposed to?

 

[indawindica]

It says on the bottle not to use water with a ppm over 100. Whats your water source?

 

[Fancyhuh101]

So water source is Tap water , and i do measure ph after I mix it and it is in the right ph range always

How do you measure ph? The electric meters can get out of calibration. I like the little drop in the vile that turns colors. Keep it yellow (adjust with the citric acid after you mixed your nutes)

honestly i am also growing in coco coir and right now i am using advanced nutrients(i am changing nutrients after this grow). i had my plants in 1 gallon pots of coco coir and after a month of veg they started getting damage like yours i transplanted into a 2.5gallon pot and all my problems went away.

also have you checked the ppm's of the tap water your using? its probably not the problem but make sure your tap water doesnt have high ppm's, if it does change to ro water.

also i have been using advanced nutrients since like 2015, i have never had 1 problem with PH. advanced nutrients is very good at keeping ph stable, i honestly wouldnt worry about ph issues if your using advanced nutrients ph perfect.

and if your in coco coir why are you using regular nutrients made for rockwool or dwc? if your using advanced nutrients buy the coco-coir specific base fertilizer like sensi coco a and b or connie coco a and b.

just my 2 cents peace.

 

[Fangthane]

I think my main reason for never really using it was because it didn't put my pH anywhere near where it was supposed to be using tap water. The bottle specifically recommends RO or water with under 100ppm. When starting out with water that's pH 8.5 and 140ppm, it didn't adjust properly for me.

So I'm guessing it's salt build up. Which often hits early flower If you've been feeding heavy through veg and it's been drying out then salt build up will occur locking out nutrients.

 

[Bushbaby11]

Ec?
Ph?
Coco retains calcium so you sometimes need to use calmag along side your normal nutes.
However without looking at the pictures PROPERLY i would say you've over fed (nute burn) with possible salt build up (nute lock out)


Flush and go with half dose. Make sure ph is in range!

 

[Kola_Kreator]

You are underwatering as in too little volume/ severe lack of run off. Because you are not properly watering to run off the excess nutes that the plants are not eating is building up in the coco and causing nute imbalance and high EC at the root zone.

You need to flush them with a lot of plain water, about 10 gallons per pot. Then feed with plain water only for the following 2 days. Then start feeding nutrients at half the recommended dose.

To grow in coco you need to water several times per day and each time water until you get about 20% of the feed volume in run off.

You are close to total lock out but these plants can still give you some decent bud if you get to saving them right away.
