Coco for the first time

[PhatJay]

Thanks for your input,how long have you been growing in coco?

A couple of years. My first two grows are logged and linked to in my signiature.

,do you start straight of at ph 5.8 6.3,

Yes I start at 5.8 and continue with 5.8 all the way through. Although a little pH drift is not a bad thing as long as it is within range.

I ask this because once my cuttings had rooted I put them in 10 litre pots,coco professional plus,ph was 6.1, I use plagron a and b,first 2 weeks they stressed and lost colour,added some calmag and enzymes once a week and they picked up a bit,

I find that I need to add a little calmag in the first 2 weeks of flowering. If I don't the leaves go a little pale and you get brown spots start to form. This is quite normal for coco from speaking to other growers.

when I flushed out the run of was 6.2,

You cannot measure the run off from coco in the same way you would other mediums. The small particles in the coco effect the readings. Just measure what goes in and don't worry about measuring what comes out. If you are dead set on measuring outbound PH you are going to need to buy some filter paper and visit Canna on youtube for the instructions on how to do it.

I was told to drop my ph and up the food,I was giving them 2ml to a litre,dropped ph to 5.5 to 5.8 and upped food to 3ml a litre

I am actually using Plagron as well (I got a freebie at a show), The dosage ranges from 3.3ml per litre to 4ml litre. I have never used Plagron before but I am 2 weeks from harvest and everything looks the same as usual.


P.S. Can you break up your text next time. I saw that wall of text and nearly didn't bother replying. My eyes!
