<span class="link_user">@Mia_BIOTABS</span>, Three of them are running on BioBizz and two on BioTabs as a small test. I didn’t list the exact nutrient amounts because the website doesn’t allow entering grams. I always follow the feeding chart, except for the tablet.
<span class="link_user">@Mia_BIOTABS</span>, Hello, good point. The issue was that when they were still seedlings, I gave them around 250 PPFD based on the meter, which turned out to be too much. Later I read that this can damage young leaf tissue, and as the leaves grow, these symptoms become visible. I first thought it was a magnesium deficiency, but I quickly realized it wasn’t. With your nutrients my plants always turn out great, this time it was simply my mistake. Greetings and thanks for checking in :muscle:
