week 3 is a go. filling this out afterwards so having some trouble recollecting to be fair.
- #1 this week went up to 800ppm for the first batch. switching to flower nutes for batch #1.
- #2 second batch is getting about 550 right now, with mostly just some calmag, and a little nirvana and supertrhrive ph'd to 6.4 ideally.
- looking like run #1 is starting to go into preflower which is nice because our previous 'aautoflowers" didnt' flower automatically even after 8 weeks.
- recalibrated PH pens. I probably need a new one (or store it differently)
- after running a full decontamination in the form of nematodes, still the fungus gnats seem to find their way in after some time. Seeing only a few here and there though luckily.

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.
