Yellow leaves wtf!!!!

Some of my leaves are turning bright yellow, not burnt just yellow. Anyone know what is up with this? Could it be a lack of light because at the moment im sort on light in my box.

sound like nitrogen deficiency, you prob need fertilizer

It's a Nitrogen deficiency probably. What kind of nutrients do you use? I,d use 10-10-10 if you can or get 20-20-20- and dilute it. I used Miracle grow Liquid Plant Flood in the dropper bottle for vegging my girl, it worked alright for me.

ya as of now im not using any nutes cause my plants are in mg moisture control soil that feeds for 3 months and i didnt want to nute burn them by adding more nutes. Im transplanting soon into larger pots and the new soil with be a mix of organic with perlite and maybe dolomite and some lime for ph, then i will be adding nutes. Thanks for the help guys!

it's not a nitrogen deficiency in MGMC, that crap bit me in the ass bigtime

probably nute lock/ph issue, MGMC can be used quite successfully, but it has tricks to it

get it out as soon as you can, sounds like you have a good plan

it prob. is an n def. yellowing leaves tell you that. but i think you're right, it's the mg. i've seen people use it successfully, but more often than not, there are problems. you have to "know" how to use it, LOL. to me it's not worth it. just get some real nutes. pure blend makes some good, reasonably priced nutes.

ya this is my first grow and i just used what ever soil was at my house i.e the MGMC. i had no clue it was difficult to use/work with until after reading about it on here, which was to late. but anyway the problem is not terrible yet so hopfully they will make a strong come back after i transplant. thanks for all your imput guys!

could be n deficiency in the plant, but not because MGMC lacks n
the stuff is loaded with n, but it may not be getting where it needs to be

to the OP, run do not walk to the nearest exit, from my experience your symptoms will progress rapidly unless changes are made

one last thought on MGMC, i can see why some growers love it, it's probably one of the cheapest sources of nutes available, once you know its mysteries
