Buddha2started grow question 7y ago

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?

Hi @Buddha2! Yes it seems so. You can add a slight dose of Cal/Mag in every waterings, until the issue is solved. In order to prevent such issue to appear, next time add Cal/Mag once a week into your feedings. Hope this will help, happy growing!

Twisted/mottled growth Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?

What's wrong?!Can anyone tell me what's going on with this? Leaves are getting white markings and are fairly limp to the touch (although they are not drooping). I've checked underneath and there are no signs of any bugs... nothing flying through the air... All other plants are ok!

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

Slight discoloration in the leaves The leaves are starting to get slightly discolored on the edges, what could be causing this? Could it be the white flies? Or could it be too many nutrients? I am giving the plant a bit of Canna A and B, although it's meant for hydroponic, it's all I have at the moment.
