Hi,

I'm new here reaching out looking for possible answers as to why my Zucchini squash's new leaf has light green-yellowish blotches. Is this Squash mosaic, or simply too much calcium or too little maybe? The older leaves are fine. And the leaves that are growing now, after the one pictured below, are fully light-green (making me believe it's a deficiency.) My cucumber (Marketmore 76) at the same time also had a problem: its new leaf is distorted looking (not flat but bulgy and bending downward but doesn't seem wilted, just seems its growing this way because of the distortion.) They're both in the same tote, so have the same nutrient mix.

If anybody could help, I appreciate it. Also, I'm new to hydroponics, and gardening in general.
