Somebody Help! ASAP

i have no idea whats going on. im getting ready to start flowering and im noticing this on a couple plants. can some one tell me what im doing wrong

Got pics of the bottom leaves as well, can you make the pics a bit bigger too. Thanks

the bottom leaves are healthy and but the area i took pictures of is on the new growth and is spreading. i took the pics on my phone. i dont know how to make em bigger

Hard to tell, have you got a lot of burnt leaf tips or is it more localised?

ive got a couple burnt tips on each but the faded light green area is more localized and on the new growth. what chu thinkin it could be?

What nutes you running??

im using the whole line of GH nutes

Pics are kinda small, but is the yellowing between the veins on the leaves??

Check out the pic on #3 of this thread. https://www.rollitup.org/marijuana-plant-problems/434409-magnesium-def.html
If it's yellowing between the veins yet the veins remain dark green it's prolly a Mag deficiency. Are you running a supplement like CalMag through your Veg and into bloom. It's a great product to help with this common def.

or you could water with crushed epsom salt to help fight, but i'd use something else. I do 1/2 strength CalMag, all the way through til 3 weeks from harvest.

preciate it mr.green....imma go out to the store and grab some asap. on the second picture its kinda hard to see but the edges are yellow light burn but the leaf is very brittle and is browning. do you kno what that could be. its on a seperate plant and a different strain. its on my pineapple express and its in the middle of the plant and is only only 2 leaves

i appreciate the quick responses from you guys!!

It might affect it a bit differently cuz of strain, but are both plants yellowing between the veins yet the veins remain green?? If so, i'm leaning towards Mag def, from at least what i can kinda see from the pics. If you could get a couple closer up pics that would help.

Did u read this and does this apply to ur plants??

imma take some more pics as soon as i get off. but yea that picture helps alot! preciate the help

A small dose of epson salts or cal/mag won't hurt here, a ec or ppm meter would clear up the problem quicker. If you got mag problems maybe calcium problems as well, garden lime crushed to a fine powder with a pestle and mortar administered to the soil and watered in with a bit of epsom salts in the water should show results on the plant in a week or less, look for stems to start turning green from purple and leaves to stop drooping. Add garden lime to your soil before planting in it, it is mainly calcium with some magnesium, finely crushed it will work quite quick, from the packet it will probably take a few weeks to activate. When i had cal/mag problems it spread quick but also cleared up quite wuick. Peace
