Sup guys, i'm starting to get some problem because my Plants are in flowering now. The first three pictures are from the same plant, last one From another plant. I maybe think magnesium for the second one? Thanks ik advance
Add a teaspoon of epsom salt to a gallon of water and water the plant with it next watering. I do this once for each plant and I have yet to run into this issue. I grow organic though, so I'm not so sure if you are using nutes.
For the first plant I don't (yet) as it is only 3.5 weeks old. I have some MG-Cal booster here so that won't be a problem. What's the last picture though? I guess it's maybe a burned spot from getting too close to the bulb or is it a deficiency as well?
