Pax grow

SCROG is where you use a screen or net to even out the canopy. As the plant grows through the screen you tuck it back down under the net. You don't need to top a plant to correctly SCROG. What it looks like your doing to me is mainlining. Creating even growth for all tops to get the same amount of nutrients. Its looking good. You will want to cleanup the lower section, But I would wait for a week or so to let her get some growth in. If you are planning on adding a screen and tucking then I would let her grow out a bit, Add your screen/net and once the net is 50% filled flip to flower. The first 2 weeks after flipping keep tucking and the screen will fill out. Then do some cleanup of the lower canopy below the net. Happy Growing

Hi there Tckfui, this looks like calmag deficiency you're right. this you can see from the newer growth being affected first and the fact you have been adding a bit more in the spray than usual. You know that absorption rates in the leafs are 80% efficient compared with absorption in the roots which is only 20% efficient. so it became a (pretty rare but possible) Mg lockout. If you can try to flush, go for it. water until runoff, then add 20% more water. Then skip Mg for one or two waterings and add it back again. Some genetics or phenotypes are just a little more sensitive than others , that's all. hope this helps ! 🚀

It is nitrogen deficiency and would not worry. The plant is trying to finish up. Would add additional potassium and phosphorus, light to no nitrogen. Let the plant Naturally defoliate itself from the bottom. Should be ok and work good from here out. Good luck and happy growing 🌱
