Organic grow, auto ultimate. Deficiency day 55, HELP!

[OrganicPassion012]

Dutch passion auto ultimate, day 55. Organic grow.

Bio bizz all mix soil

Bio bizz grow, bloom, cal/mag, top max.

What is going on with her leaves?

First I noticed red spots on the bottom fan leaves, I fed cal/mag and then the problem went away, come pre flower. It was back, worse than before. Red spots on the veins of the leaves, stems turning red, green underneath but red on the tops of the side stems, main stem appears to be showing red lines down it, the affected leaves with the spots appear to have discoloured, turning lighter with blueish/dark undertones,

I last fed her cal mag 4 days ago, not seen much improvement and it has spreaded up the leaves, right now, it's fan leaves affected mainly.

It's climbing the plant daily.

Last nute feed today = 2ltrs of water containing 1ml grow, 2ml bloom and 1ml top max per ltr.

I am waiting to see how she takes it, buds appear to be growing still, sugar leaves popping out everyday.

13ltr pots, all organic.

@OrganicPassion012 We need to see diagnostic pictures in regular daylight with the grow lights turned off. Based on your description are you feeding Cal-mag by itself? If so that is the problem.

Whenever you feed - fertigate the plant it must be with balanced nutrients. If you fertigate one or two elements alone that fertigation will wash the "Balanced" nutrients away from the roots and only the out of balance elements will be available to the plant. This will cause a lock-out. This is not the only way It can lock-up but is is a sure way.

Please fill in this form: (copy and paste part is below, this first one tell what specifically to include)
