2x2 3 autos grow

Looks like a possible deficency crawling in. She's looking light in color also. Try feeding with a higher nutrient dose. 🤘😤

Needs more nitrogen and magnesium.

I believe this falls into the other answer I gave. Since it was on every plant in some degree is why I felt it was ph problems. The plant veins turn red when magnesium deficiency is present. Just if your roots are locked out because of ph then any deficiency can show up really. Always use a calibrated digital ph pen. Good luck 🌲🌲🌲👊

Ok well looking at your plants in that week I see either 1 major issue causing you problems. What is your soil ph? Water going in? Extra coming out? These ph numbers are very important. Should test every watering. Now if for some reason that is all in range you are suffering from nitrogen deficiency and cal mag deficiency. Possibly light burn but not sure on that one. If you need more assistance, send me a message. Good luck and happy growing 🌲🌲🌲👊
