According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78.

Yellowing Leaves The leaves on one of my plants are really starting to yellow. To me, this looks similar to pictures of plants in late flower, rather than the examples of nutrient deficiencies. Have I read this correctly, or should I start worrying?

First week and never had little plants struggling so much to grow. Please, read my comment about the first week to a detailed explanation of the problem. The question is, what else can I do, except from waiting? I don't want to over do (again)
