hey guys starting to see some issues in my chernobyl. everything looks fine other than some of my mid/top fan leafs are starting to yellowish around the veins of the leafs. rest of the leaf is nice and green. showing a little bit of leaf curl upwards making me think its a magnesium issue but i just fed all the plants a good amount of magnesium right before this happened. maybe too much mag? idk what to think so what do YOU GUYS think? thanks in advance for any help!

wish i could take a better pic but cams crappy.
on the bright side look how frosty everything is in the background

Looks like it, might wait a couple days and watch to see if the yellowing progresses, but also on the 2 leaves at 7 and 8 o' clock, is that a shadow or a P def. also?

just shadow i think. been keeping a eye out for P defs since im in flower. only issue so far is this. been 2 or 3 days since i watered this with some cal mag and a splash of micro nutes. havent seen much progression but i wanted some 2nd opinions before just sitting and seeing what happens.

Would agree with Baka, and say wait a day or three.. and see if it's going to get better as it goes through some of the magnesium, or show more in the way of a headache.

If you still see some after another couple days, try another small shot of Cal/ Mag.

Without question! I'm almost certain that the Mag isn't being locked out due to you having calcium overload, unless you've spiked it and didn't tell us.

last week i checked PH using the testers you add water, soil, and the powder. said it was around 7. i top fed with just a little tiny bit of powdered lime. dont think PH is the issue but shortly after that is when i started noticing this issue.

Unless you used Hydrated lime, or a lot, I think that was just a coincidence.PHRANGECHART_zpsddd4a5c5.gifView attachment 2551331

he said seemed to be outgrowing its container and the thing is that i forgot to mention im in the early stages of being rootbound with these plants. BUT! ive been rootbound several times and never had this issue. rootbound plants usually start at the bottom and work their way up and look more like a potassium def. the issue im having looks more like a calmag issue and is starting at the top from the veins first.

Ya, I think he just saw a coincidence since he repotted AND fed, but the article indicated that it was Iron, so that follows with the guy's feeding.
Mine has been rootbound in her 5 gal. for almost a month, and I don't have the yellow, and also when she was in the cup, I waited a week too long to move her and all she did was get kinda droopy like over watered.
Hope that works for ya!

Sorry man, I just went and read again, it says Boron.
Google it man, I'm looking further, and I'm finding Manganese, Mag, and others.:-(
http://www.growweedeasy.com/marijuana-symptoms
Problem: Cannabis leaves and roots show abnormal and slowed growth when showing a boron defiency. The first signs of a cannabis boron deficiency is abnormal or thick growth tips. New leaves may display chlorosis (yellowing of leaves). Stems may become rough or hollow. The plant may look like it has a calcium deficiency because boron is needed for the plant to properly use calcium. New growth is affected the most, and may look like it's been burnt or scorched.
Solution: Boron is not absorbed will without enough potassium and nitrogen, or if there isn't enough moisture. You plant may also exhibit signs of a boron deficiency if the pH is too high or low. Flush your system with clean, pH'd water that contains about half the nutrients needed for the plant and watch to make sure that the problem clears up for new growth.
