RT ......... did you see the pic I posted of the leaves on here? I dont have a test kit but I have done as much research as I could in the short amount of time ive had since this prob happened and calcium or Mg is what I had pretty much decided on also. I havent had a test kit to check the ph#'s and that kinda stuff, no $ so how would I go about straightening this out or even guess-timating on what mix to use to fix the calcium issue?

I haven't used CalMag in years, (I use unsulphered molasses) but once a week per instructions is a good place to start.
Homework builds character and a strong knowledge base. Don't stop researching. :thumbsup:
Blankstairs: This is greenthumbs thread. But if you'd like to start your own thread, I'd feel more comfortable discussing your issues there. Thank you.

Brown Spots & Yellowing of fan leaves @ 4 wks flower.
So after just one dose of Cal-Mag my girl is already improving!!!
The leaves with the brown spots are no longer yellow, they are green! As RT said, old leaves are old news, so the brown spots are here to stay, but I am pretty sure my girl is on the road to recovery.
I now have a better understanding of Cal-Mag deficiency, and have seen it in person. So although my plant was stressed, I now know what the symptoms are. Everything happens for a reason, and this is certainly a learning experience. Also, as I am still somewhat of a newbie to indoor growing, and I now have a much better understanding of pH and nutrient lock up.
Thanks again for your help Rusty!! I will keep everyone updated so they can learn from my post! I will post some recovery pics in a couple days.
:thumbsup:

be careful when using bottled water see where it is being derived from. if it isnt put through reverse oasmosis it is the same water u get out your sink maybe even less purified. Plus its expensive most grocery stores and all walmarts have a reverse oasmosis filling staion for $.35 a gallon. that way you control whats in your water. It has a ppm of 128 and ph of 7. all water should be 7 ph not 5.5. After you add you nutes ph naturally drops perfectly to 6.5 if using organic nutes. you can almost judge the amount of nutes in your water by your ph. if you put too much nutes in your water your ph is going to be low.
