    Why do you think the purpling is phosphorous?
    Every time I've had purple leaf stems, adding mag and/or correcting PH fixed it.
    Ideal PH range for mag absorption is 6.0 - 7.0 for soil.
    6.0 - 6.5 is best for hydro.

    Noted. That's why I thought I was getting a nutrient lock out, due to the nitrogen overload, even with FF's Happy Frog mild soil.
    As you say...if I only added 1/2 the recommended dose of Alaskan 5-1-1 (every other feeding)...that should not be too much nitrogen.

    I feel as if I should show pics just for a general evaluation of my first time discreet quiet one plant grow, in a 32x32x63" tent. 3 gallon pot. That little purple spot at the bottom is a 120mm PC fan drawing in air from the room window (opened enough to accommodate the 4" 190 CFM exhausting air out). It's pretty damn quiet (neighbors). I've since gotten rid of that auto waterer made by Continental. You can't add anything to the water reservoir or it will clog the pump. My plant is a slow grower. I plan to start the flower stage 14 days from now.

    PS. How do I change the order of reply posts seen for any topic reply? I want to see the latest reply post, not the first one 5 years ago. :-)

    Because of what I see and read. The elements all need to be in balance to work together. If one is low or high it can affect the uptake of another. Nutrient antagonism and such.

    The point of my post was to use a balanced fertilizer rather than the mostly nitrogen fish stuff. Seemed like the plant needed everything restored to balance it had multiple deficiencies.

    In my system adding mag alone or in cal mag or mag sulfate will worsen the problem despite the normal signs like striping on lower leaves. Plenty of mag in the soil and nutes and some in the water too but if I have calcium buildup that is usually the problem in my garden.

    Many many variables possible. You likely need the mag you add.

    Alaska fish oil quart (5-1-1) was only $5.99 at Home Depot, so I bought it. I'm slowly going with other makers of liquid fertilizers that maybe offer more micro nutrients. 5-1-1 isn't bad for veg growth, I suppose.

    Need something more like 20-20-20 or 3-1-2 or close.

    You are missing the K part of the NPK. Even miracle Grow makes a liquid organic 312 nute. Micro nutrients are also called trace elements for a reason. You need very little of them compared to the NPK.

    Mag and calcium may or may not need supplementation depending on your water and methods.

    The consensus seems to be that darker than normal leaves are caused by a nitrogen excess.

    I agree. That is why you want a balanced ratio at the proper strength for the plant.

    Hello. I have a question about fertilizers. For example, 20%-20%-20% (NPK) fertilizer is 2 times more concentrated than 10%-10%-10% (NPK) fertilizer? So, first one should be used 2 times less than second?

    Not exactly. You just measure and mix less to get to the desired ppm.

    I have read that i need to feed Mg and it is located in Epsom salt. What is that? Where can I find Mg more?

    You've been a member since 2011 and you don't know what epsom salts are?

    English is not my mother language.. so thats probably my problem. I am not a troll :)
    How much these salts can be used? Like, a teaspoon on a litre of water? And how often?

    Just buy a product called Cal-Mag or Cali-Magic (Google it). Follow the directions on the bottle.

    Mega-Crop dry nutes. 5 dry grams per gallon. No other additive. With my own feeding schedule.
