Hi all! My plants grow in the PM coco and have 15 days. They grow very slowly and are small. :blub: I use PlantMagic Fertilizers coco grow a + b (about 2-3ml/1L) and root stimulator (2.5ml/1L). EC0.90 and PH 6.0. Previously I cultivated in Canna coco and did not have such problems. What can be due to slow growth? Thanks for replys. :B):

Its very easy to over water small plants in big pots.


I just had another look at the pic after your comment.
If anything, those pots look a little dry to me.
Also, the plants are right next to the passive intake.....what is the temp of the air comming in through the vent??

Whats your airflow like mate i used to run seedlings with the fans off to increase humidity in the winter and to keep temps up.i also noticed slow growth during these times but it was all i could do to keep a happy temp and enviroment or as it worked out not so happy . your got to have constant supply of fresh air or co2 may be this is your prob.

I use 6"fan 420m3 / h (but is on 40% of power). Now I use the 400W MH. Overdose fertilizer is excluded because the plants were light green. When I increased the dose of fertilizer plants have become a nice green color. I think it might be the fault of Plant Magic coco, or from bad watering just don't know whether too much or too little? :wallbash:

I'm worried because it is automatic and will soon begin start to flower and can be dwarfs. For comparison, I give pictures from other growtent on the 15th day of grown in soil. How do you think that they can stunt? Is it worth to grow them? :yinyang: Thx!

As far as I am aware PM get their coir from the same place as Canna, it's the same stuff. Coir is next to impossible to overwater unless the pots are sitting in puddles of liquid.

Do not let the coir dry out even the slightest. The roots should be racing through the pots.

How often do you feed? Do you use water at 20 c or room temp? Do you water until you get run off?

They look a bit hungry? It is worth experimenting on a few with an increased feed maybe.
