my strawberries are turning very light yellow and seems after all work done the are going to die…
i got some kind of tiny eggs under the leaves ans I spraayed with soapy water, know they turned light yellow leaves with green veins. I tryed iron chelate but i havent seen any mayor chenges yet.

That yellow leaf thing is a real problem. I’m in pretty much the same boat you’re in. Once the leaves start to yellow, it signals the ultimate doom of the plant, it would seem. I haven’t figured it out yet, but am slowly realizing why strawberries are so darned expensive in the store. I know a strawberry isn’t supposed to be as big as a tennis ball, still there’s something to be said about the commercially-grown (chemical) ones in that they are at least consistent. Wish I knew the answer!

OK! go it fixed… dissolved powder iron chelate in 6.2 to 6.5 ph water and a week later… beautiful very green huge leaves. Plus used after that the fertilizer you have recomended, from Plants that produce, Richard Frost I think is his name, it worked…
