    I don't know how I did it but most of my yesterdays post didn't show. I just noticed it. Maybe when I added the pictures I over wrote the text. So here is the full post. A little history, I used ResinRubber's posted soil mix. I used Alaska Fish Fertilizer instead of fish/seaweed emulsion. I did use the mycorrhizal but I think mine was mycorrhizae. I mixed it many times over a week to mix it well. 1 Bag Promix (4 cu ft)6 cups Bone Meal - phosphorus source2 cups Blood Meal - nitrogen source (as an expense saver 6 cups Bone/Blood meal mix may be substituted with varied success depending upon mix ratio)1 cup Epsom salts - magnesium source3 cups dolomite lime -calcium source & pH buffering2 cups fish/seaweed emulsion

    Here is the rest, I hope.


    Here is the problem, during the third week of flowering some leaves on one plant started turning yellow, I gave them 1 Tablespoon of unsulphered molasses in a gallon of water a couple days before this happened. As the 4th week of flowering started I gave them

    It will not let me post the rest. Now it just posts the time.

    Is it because I am copying and pasting from a Doc file?

    cut and paste is acting up, but I don't know why my earlier response is now missing either.


    but I'm not a soil guy, my best guess is that you are nitroing out a little early, don't panic at all. leaves will yellow when they start to run out of nitrogen. you don't want to add a bunch of nitrogen late in flower though so it's kind of a learning experience. Your crop should be fine, trust me when I say I've seen far worse.

    Looks like the edge serrations of your leaves are pointing up, if so it is magnesium, use calmag as part of you nute mix, 5 ml per gal every watering.


    Also the intervainial chlorosis is a sign of Mg deficiency.


    Im sure i spelled that wrong but you get the point.

    At second look it looks like a possible potassium deficiency also, the mg looks like a minor deficiency but still there.

    Thank you for the replies.


    They are just starting week 6 of flowering. Should I give them calmag at this stage of flowering or should I let them finish without it.


    In my next grow when do I start giving them calmag?


    Thank you

    I run cal mag from week two of flowering all the way to the week I start flushing. greenjah and nippie I think pretty much nailed the issue on whats happening.


    jaxn, not a bad looking bunch​ of ladies you got there. Keep up the good work.
