Cal/Mag or Nute Burn

HighlyEduc8edstarted grow question 3y ago

Cal/Mag or Nute Burn Week 3 of flower Doing some defoiliating and noticed some spotting on the leaves. I watered with Cal/Mag the next day. I thought possibly nute burn but I'm only giving a .25 of the strength every 3rd water so I don't think that's it. Thanks in advance

It doesn't come off. I use water from a local spring. Its very acidic so I use ph. Yesterday was the first time I've use Cal/Mag this grow and I plan on using it until harvest

Does it wipe off at all when you touch it. Could be some kind or fungus. Or magnesium or potassium. What kind of water do you use. Try upping the dosage of you cal mag and see how she responds. Give her .25 with every other watering. I hope this helps, good luck

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloom

Can I combine treatments into one?My question is pretty simple. I wanted to give my plants a light foliar treatment and also wanted to include some neem oil. Is it OK to mix the two together or should I do it separately? I'm sure it's likely fine to mix them, but didn't want to take a chance. Thanks for helping!

Dark leaves in DWC Hey guys, this NL auto is very dark compared with the other plants. Also had some spots on the leaves, but I did a Res change and defoliation of sick, bud site blocking leaves. Could it be a Cal-Mag deficiency? I was thinking nitrogen toxicity but no clawing of leaves.
