Hmm that is such a strange problem, I’ll see if there is anything else i can do… you may want to try making another account though, this system can be a tad buggy at times..

I’m happy to hear that your tomatoes are doing well, what are the compost pellets that you use? If your tom is doing well without removing them then you should probably go that route in the future, the unestablished roots in seedlings are really susceptible to stress which can lead to the plants not being able to adjust to the change in environment. Changing nutrients is usually something I play by ear because it depends on the plants (green leafy things don’t necessarily need the bloom stuff, fruiting plants however definitely do need them). Tomatoes love a pretty rich nutrient mixture, and in my experience they don’t mind the full nutrient mix early on, but you can wait a couple of weeks usually, if you see flowers definitely use the bloom. For a more precise guide you may want to check to see if the producer of your nutrient solutions provides a nutrient schedule on their website, if they have on it tells you what to put in each gallon based on what week you are in.
Watering timeframes really depend on your system if yours is anything like the traditional WF drip systems, continuous watering shouldn’t cause any problems. So long as the water is flowing/ dripping/ otherwise aerated, most plants shouldn’t complain. Rule of thumb, roots should always be moist, the more ’active’ the water is the better.
Hope that this helps!
