Little brown discoloration on older leaves
Elgaranswered grow question 5y ago
Hey, these are signs of calmag deficiency, these brown spots are the main symptom. Add some calmag and you’ll be okay 😊

500 or 700 ppm ?
500 is a bit low, 700-750 ppm (NaCl 0.5 scale) should be fine

Tiny Brown/Bronze spotsMy Dr. Lemon plant has a few orange/bronze spots on some of the middle/upper leaves, Looks like a calcium deficiency, but I'm not sure. Anybody have an idea of what this could be? Feel free to check out my diary on her for more context!

What is causing this Leaf discolouration overnight after a lot of tent work yesterdaySpent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants.
I did lower the plant (was way too high) so may beight burn - but it’s only on some plants
I did make two mixes of water/nutes

Cotyledon issue from seedlingHave seedlings from Auto Colorado Cookies (Dutch Passion). One already has cotyledons, but not opened yet. I see some yellow and bigger brown spot of the tip. In the beginning I had 250 PPFD, could this be the issue?
Now I am around 100 PPFD and put the light a bit up. See photo.
