Bud Leafs showing yellow signs but why?

[Fiete]

Hello, every time I have a Plant in the late flowering I always dealing with some yellow leaf tips between the Buds but why is that?


I growing in Coco flooding my Flood Table with PH 6.0 and PH 1.6 Water but i I don't know why that's happens?

How often do you feed and what are you giving them in terms of plant food?

A coir grown plant should be fed several times a day.

Flooded with a Ebb and Flood System 1 - 2 times a Day

Feeding Canna Coco A&B with litte PK total Ec 1.6 it was nearly 3.0 Ec so i flush it out to 1.6 and only feed less the next weeks.

I empty the Tank and refill it with freh water and litte low Ec 0,7

seems like nitrogen excess mixed with watering or ph issue (probably ph of water using for watering issue)

PH 6.0 is fine yes too much Nitro that's why i reduce the Base Nutes

Pk boosters cause more problems than anything, especially if it's timed wrong.

If your ec was 3.0 then that tells you you never needed to feed it as high as you were doing.

Obviously some stains will respond differently but generally it's overfeeding.

If your running multiple feeds a day you'd be better running at 1.2- 1.4ec, try 3 floods so you get less dryback
