- #1 started adding some slight pk boosting and still giving calmag.
- this week i've flushed both PP#1 and GG#1 because signs of toxicity (i think it was lightburn but i wanted to be sure so i flushed it with tap water and then fed it with nutrient solution until there was significant runoff)
- #2 round two is doing great. they are also loving the real sunlight :)

If you are asking, "did my light coming on 5 hrs early, cause light burn", I would have to say no.
Timers are constantly screwing up, or power outages wreak havoc with your setup timings, but I have not seen that symptom.
I see in your diary comments, you thought you saw toxicity earlier, and had exposed it to sunlight?

This may be a previous issue, and moving plants from grow lights to natural sun, to me, would make the plant react differently.
IMO, if your grow lights do not provide IR and other natural (non-blue,non-red) lighting, that could be a problem.
