this a cal problem

Running hydro, ro water, house and gardens nutes, A, B, root excel, Algen Extract, Nitrogen boost. 5.8 ph. ec 1.2

I am about 1.5 weeks into veg and the lower leaves on some of the plants have redish/brownish spots.. thinking cal/mag def perhaps? Nute burn? new to hydro.

any ideas?

thanks!

Since the subject line for this thread is more of a statement, not a question, people may not understand what you're looking for.

I'm assuming this is a clone since it's so developed and you're just 1.5 weeks in. I don't know anything about clones (i.e., whether this was an inherited problem or a new problem), but that does look like a calcium deficiency to me. A little cal/mag added to your nutes will prevent it from affecting more leaves.

Sure looks like cal to me. However I would be wary of adding any more cal/mag to your water until you know what your starting ppm is. Most tap water has enough calcium to support plant growth. PH lockout is the usual cause of cal def. Addim more cal/mag will lock out other nutes if you are not careful. Make sure your PH meter is calibrated right and start there before adding any more nutes to your mix.
