Ph Problems
One of the first signs of having a slight ph problem is, your plant having part of the leaves kind of twisty, spotty with brown, yellowish, red spots within each other.
Sometimes they donā??t have to have all the colors, they could just be spots that have yellowish brown, or just reddish brown and can happen anywhere on the plant. Mainly starts on big fan leaves then goes to little leaves.
When this happens you need to check your soil ph, water ph before and after adding your nutrients. One of the biggest causes is adding nutrients like earth juice; they take the ph down quite a bit. Also can happen when you add bone and blood meal to your soil, that will throw the ph off as well, so itā??s smart to test the mix before putting your plants into the mix. After the spots happen you will soon see nutrients being locked out, when that happens DO NOT ADD ANYTHING TO FIX THE PROBLEM UNTILL YOU GET YOUR PH FIXED!!
You don't need to have fed to have ph problems. What is the ph of the water you are using? Take a ph sample of the run-off on that plant and let us know what it is.....
