Cal deficiency?

[Z Pops]

Just looking for some confirmation. Fastbuds strawberry pie, OF, trio and cal mag, Mars hydro sp250.

Growing 2 plants of this strain. Only the one on the right showing symptoms. Maybe need to up the cal mag?

Looks more like water damage to me, but I will be interested to see what others have to say. I would definitely not hit them with any more cal mag unless someone more experienced than me advises you to. More often than not, more cal mag seems to cause more problems with lockout than it does to fix anything.

growing the same strain from FB and my leaves look the same. In fact almost every autoflower I grow appears to have a cal/mag issue. I have tried everything from no Calmag to full dose Calmag to no avail. In my search for answers I have not found any but this seems to be a common autoflower problem. If I don't get it worked out after this grow I'm switching to photos. On the plus side the plants still grow like crazy so I'm not sure how bad it's hurting the plant. I've been researching and trying to solve this problem since June on three different crops.

Hey man. Fill this out. An expert will ask for all this info anyways.. I would also hold off on the cal mag. Excess nutrients will lock out others and make the plant look like it wants more.
