Anyone recommend any DWC grow journals

Ive had a search and read a few, can anyone recommend me some good dwc grow journals.

Ideally where Pythiam/Root Rot has been overcome.

2-3 ml/gal of Hydroguard every 3-4 days will fix ANY root rot problems you have. 32$ a bottle max. You don't need grow journals to fix a root rot issue. Dutchmaster Zone or H202 bombs work well too. If you are having such an issue with it that it isn't being controlled or being responsive to positive treatment than your environment might not be right.
