Why are all my early cucumbers are sick chlorosis

If such an article I read the May 25, 2019, in my eyes, prices would not it have been! But the Internet a little pleased with the information. Without my guesses - "chlorosis" - Yandex did not understand what those yellow leaves of cucumbers. I hope useful to you experience the real solution to the problem of chlorosis in cucumbers. Photos attached :)

In the last year cucumbers were great fun. Planted seeds May 25 directly to the greenhouse. Only a couple of seedlings planted.

Total received chic bushes. Those seedlings that were and those that are planted in the greenhouse. Leaves up to 40 cm! The harvest is excellent.

This year really wanted an early harvest. Did not work out! All 6 bushes sleek cucumber seedlings of different grades with vermicompost after transplantation to the greenhouse steel suffer from a lack of elements (chlorosis). Pale leaves, only the veins green, and so all the lower leaves. And small!

I planted them in early May, relying on an infrared heating greenhouses under the ceiling. Soil temperature was measured, it was low, wait 10 ° C and planted, thought, dogreetsya zemelku. Now I know for a long time the soil is heated. Highly. At first, nothing, and then my thought so Rastishka!

Six very early kutso looked close to a couple of more late cucumbers planted much later.

My diagnosis: the roots from heat and lack of the necessary elements are poorly digested. Only caught on May 26, after the first cucumber instead of the planned superurozhaya. Foliar feeding spent ferric chelate (from Leroy Merlin), magnesium-zinc-boron, followed by calcium. With a break, of course. And we are talking about micro-micro doses, rather than baiting the harvest.

The logic: if the roots are poorly assimilated, then everything is bad, all the necessary elements of cucumbers.

The leaves are not recovered, but a little prettier. Part of the removed, most unfortunate.

Then there was a complex nitrogen-potassium-phosphorus fertilizer at the root. Now, on June 9, 2019, all together 8 bushes bear fruit. And early harvest did not work!

Plus, as always, is found. I realized something about tomatoes and, finally convinced. For me it is a great discovery. About it in the next article.
