Yellow leaves near the harvestThis would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest

Magnesium - Nutrient problemDo I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly.
The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1.
Has anyone the same problem?
Thanks!Leaves. Veins - yellow between

Should I check only EC or PH is also important?I was told not to check for PH, add the nutes and check the EC, reach the level I want and that's it, is it right?
I'm also checking the water coming out of the plants, they have EC 1+ above what I gave them.
If I gave 1.5EC then it will have 2.5EC in the water coming out.Feeding. Deficiences
