Cocotek nutrients

[Harry]

Hello everyone. I was wondering if anyone has a good nutrient combination for Cocotek nutes. I seem to be having some nitrogen toxicity. This is my first grow in coco, and I'm trying to dial this in. I will be transplanting this week from 1 gallon pots to #7 smart pots. I have to water everyday right now. I'm using 1/3 strength nutrients and still getting nitrogen toxicity. Dark green leaves with the claw. My runoff Ppm is between 410-450. I'm putting 470 in. If any farmers have any ideas I'm open for suggestions

Go to the GH website and they have all their feed charts on there

I've never used cocotek but the GH Flora Series + CaliMAGic from GH works great in coco so their cocotek line should

Are you using the Cocotek Coco as well?? I am using it and I had to rinse mine 4 times to flush salts from the coco before using it. How old are the plants and how much water do you give each plant? Do you give them plain pH'd water at all or do you always give nutes? I'm curious if you may have a salt build up in the coco.

I use Nutrifield coco mega bricks http://www.nutrifield.us/coco-brick-mega-brick.html (Australian)
comes pre rinsed & buffered. Just rehydrated it, put it in a pot without any perlite and put my seedlings in it. Second grow using it with good results.

Currently mine are on Day 48, I have 3 plants and they are currently getting 3.5-4L (0.92-1.05gal) of 75% strength nutrient solution from the full GH Flora Series + Supplements every day with runoff. I aim for 10-30% runoff, if it gets below 10% that plant gets 500ml more water the next day, if it goes over 30% for a few consecutive days I reduce the amount by 500ml. Only plain watering I have done is one the day before changing from transition to bloom nutes.

There's two grows listed in my signature on my first reply up above, current one is a lot more detailed than the first grow that I posted about after the grow was completed.
