I tried the botanicare line in my dwc setup this summer and it gave me a lot of issues with the ph.
Late response, I learned Botanicare nutrients are salty and unless you have an automated PH Dosing system you will get big swings in PH for sure.
I run Cyco nutrients now and have been happy. If I could choose only 1 base nutrient it would still be Advanced Nutrients Coco Connoisseur A&B with the "ph perfect" tech. The only downside of AN is people say the CEO is a pedo and the nutrients will cause your leaves to burn at recommended dosing but end product is always fantastic.
I only use Cyco because I like trying new lines and after trying General Hydro, Heavy 16, Botanicare, Canna & House & Garden full lines so far Cyco is the best one yet. I premix my nutrient reservoirs & ph them the days in-between waterings and setting my PH to 6.0 I have no issues with PH swings even after 24 hours of it sitting with CYCO line or Advanced Nutrients line.
Note: Don't use air stones in nutrient solution it will cause separation (clouding/slime) and ph swings. Sounds crazy but I had to learn this the hard way after 3 years of using air stones in my nutrient solution reservoirs.
