started grow question 4y ago
The coloration on my first leaves is worrying me. First grow. I really don't want to stunt her. G&B potting soil, filtered soft water, Myco+ in my water, 100w AC infinity Ionboard.

Looks like its getting a bit to cold for her. Temps below 16C/60F will cause stunting and hinder nutrition uptake.

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Dunkle Flecken auf den Blättern.
Hey.. On one of my White Widow plants, dark spots have been appearing on the leaves for days, and today I've also noticed the first spots on a Blue Dream.. Can someone tell me what's going on and how I can get rid of it? Removing the affected leaves hasn't helped.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.
Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?
I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.

Listless plant
What would cause this specific plant to look so droopy and sad? Had to cut out some totally dead growth. I’m at week 7, is it too late to help it?

2. Grow with Gorilla Cookie Autoflower seeds. The deficiencies on the back left look like those on the back right, I think phosphorus based on the pictures, and in the front, it's pretty much a mix of everything but extreme. The only bud that smells when you touch it is the one from the back right, the others don't.

Taches noires sur les feuilles
Request for diagnostic confirmation: I noticed black spots at the tips of the leaves. I think it might be a phosphorus deficiency? I was a bit late in feeding my plant. In my last watering: pH 6.5 EC: 1.8 Terra bloom, green sensation, pure zym. Thanks
