Brown Rust Spots on BlackBerry Plants NEED Help!! Many PICS!

    I planted these 2 blackberry plants on June 1st and have been looking great until a few weeks ago. At that point i saw what i thought to be nitrogen deficiency so i started added fertilizer once at 1/4 strength and it appeared to disappear until last week. It looks like it is something different now that I have never seen before. There are these brown spots on all the bottom sets of leaves. What is wrong with them?

    They are in 8" pots full of Scott's Moisture Control Soil. They are both about 18in tall.

    my plant had a similar problem, it ended up being nute burn and a lack of nitrogen. also do you check the ph of your water

    Could it be nute burn even if I watered with 1/4 strength fertilizer? Would i be better off ferting with blood meal instead of miracle grow? if so what strength?

    I agree looks like a nute burn or lockout........flush throughly and let them rest without the fertilizer for a week. You might try after the flush some super thrive or other suppliment, just vitimans and hormones, great for veg. Here is a site you might find very helpful both now and in the future...http://www.icmag.com/ic/showthread.php?t=11688 Hope this helps....Good Luck:joint::mrgreen:

    The leaves I showed the close up pics of died and the leaves above are the same. I did a pH test of my soil and it was 6.3-6.5 & 5.3-5.5. Would that cause any lockouts? If so how would i raise the pH without buying ne thing at the store? Would Blood Meal work?
