Cal/Mag Def?

So im in the tent working and see some leaves that dont look great. It looks like a cal/mag Def. but im using tap wetar and didnt think I would have any issues. Is it a cal/mag Def. or something else? Any input gyus?

Also interested in the answer. Last grow had this issue.

where is the problem starting on your plant?

Mg def. you can foliar feed with epsom salt or right into soil dissolve in warm water first

Mr grass... Suiting, good call lol

Its more throughout the plant here and there. The leaf in the pic is from the top.

What are you growing in? what are you feeding them?
you have to let us know the important stuff or we cant awsner your questions

no not really. You have a pic. I want you to look at it and tell me what you think. You dont need to know a thing about what im doing to see whats not right. lets say im doing everything right but found this. so now what?

no its not heat temps dont go above 80

ok than it's MG def caused by your water. Especially if you experienced this in another grow. From the xshoot guide in this forum:

"If the starting water is above 200 ppm, that is pretty hard water, that will lock out mg with all of the calcium in the water. Either add a 1/4 teaspoon per gallon of epsom salts or lime (both will effectively reduce the lockout or invest into a reverse osmosis water filter."

Other than that anybody else? I pulled my last post because I misread your post and thought your bad leaves were just on the top!! My Bad

ppm is 150

looks like it turns out to be chlorosis. I had problems with the roots and had to remove just about all of them. Dont know why but I didnt even think about the root issue having anything to do with it. How dumb of me
