The new growth on my plants are yellowing from the base of the leaf outwards--new leaves are completely affected. I've searched high and low and can't find an answer. They have had two applications of tomato miracle grow fertilizer 2 weeks apart (using the hose hook-up to a spray bottle). Signs showed up about two days after last application. Nights were a little cold 6C and 8C respectively.

Bottom leaves are unaffected.

Could it be a micronutrient issue??/pests...

Any help would be greatly appreciated as it seems to be showing up in more plants.

Thanks,

Contact can be direct, as in mis-applied spray, or indirect, as in floated on a breeze.

So, have you, or a neighbor, used it anywhere in the vicinity?
