Hello,

I have not read anything by Jorge Cervantes, but a lot of people who help me out say to not follow his books. He is misleading. I believe those who help me, but would not rule out that it is possible that they are just giving their opinion.

I can not get the link that you put up to work.

As far as the plants. It sounds to me that you are over ferting them. A plant so young does not need alot of nutes. Take whatever amounts you are using and cut them down to 1/2 or 1/4 strength.

Next time you see a plant start to go south, change out the water like you did before, but only replace it with pH balanced water.

Are you using enough aeration in the water. The presence of oxygen in the water is vital.

I hope this helps.

Peace
