Hi all,
Bellow you will see some pictures of leaves with Mg deficiency I hope it helps others as I have been helped when this happened to me. As suggested by JAngel I gave my plants extra Mg.
Actually I gave them Ca and Mg (in a 2 x 1 ratio) and they are getting back to green within 24 hours!!!
Please, notice that Mg def. starts the yellow at the bottom of the plants, and goes up. You can find leaves half yellow and half green, specially from the veins (tiger stripes as I call that color mix). Also the new and big fan leaves (after being yellow) will start to show necrosis spots and turning up as in the pictures
Peace

Some strains want more mg way up into 6 weeks of flowering.Carbo's that are feed with your nutr give the plant the engery to burn the nutr store in the leaves and mg is stored there to help with photosynthesis.Some starins doesnt need as much as others do.You have learned a good lesson on watching the plants and seeing what they need at what time.If you grow the same starin over again two or three time you will have it tuned in to it's finest it can be.Good work 4EG. Peace
