Deficiency, veins yellowing first

[Nicoleyoung]

I've been trying to figure out this deficiency and from my research it looks like magnesium because of the way the leaves are yellowing, but the weird part is the veins are yellowing first and I believe with magnesium the veins stay green all the rest yellows… I'm not sure what to do but I'm running out of leaves LOL Please help!

Nitrogen and just old leafs. But a little more info on your grow details would truly narrow it down.

Like Mr. Furley said. Old leaves.The plants are entering flower now and draining the fan leaves. Feed for flower now.

From the tittle I was ready to say sulfur, but not! It's fall!

Well I thought I was giving it too much vegetation feed with nitrogen so I flushed it really well and it looked great for about five days and then a bunch of new yellow leaves… I can't find a pH monitor that works in my area I've had to return two of them but I took a leap of faith and added a tablespoon of lemon juice recently with Seth a tiny bit of flowering food and it seems to start getting a little worse but I'm pretty confident if the pH is off it's going to be a little bit high because it's always been when I tested it before around seven, I'm afraid to give it anything because every time I give it something it seems to give me 10 to 20 more yellow leaves and I feel like I'm going to lose them all

This is my first time growing but my friends plants have way more leaves than mine… Is it normal to basically be losing every waterleaf and only having the tiny ones around the buds left?

 

[Mr.furley]

When you take nitrogen away from your plant it will pull it from the bottom leaves if it needs it. Nitrogen is a mobile nutrient which means It can move around. If your pH is out of whack you need to start there because no matter what you give it you won't get it out of PH. Plants do lose leaves outside towards the bottom of the plant it's just the way it works in nature not getting light they need, overcrowding and just used up.

What's concerning me is every single waterleaf I guess you call it or leave that is not part of the branches with the buds are yellow now so I'm afraid to pull them off or there won't be any leaves left, but I will definitely try to get somewhere where I can purchase the correct pH meter
