All 5 of my potted plants have developed these brown crispy patches on some of their leaves. The last couple of days have been the sunniest we’ve had and I took them out for an hour yesterday. There’s no extra purpling of leaves like they got when I first introduced them to my Viparspectra light set too intensely. But I also fertilized them with full strength sea weed feed for the first time a few days ago, where as they’d been half strength before. Strangely, the 20 odd seedlings still in cell trays show no sign of damage and have had exactly the same treatment. They’re currently back on the windowsill and I’ve turned the light off but seems like the tarnishes have progressed.
