I have had some trouble but I hope I have done the right thing now to make them happy again.
First off, I suddenly found rusty small dots on a few leaves. Next time I checked there were more of them and it seemed that my plants got worse in the lower half again. There were also a few leaves that had turned brown on a good part of the tip. The rusty spots seemed to turn for worse on one leaf and that was when I reacted. The photo below is from a leaf that started with small rusty spots and now it is like this:
I read online and decided after ruling out air circulation and a few other things it had to be the PH in the soil so I flushed it. My PH was 5.6-5.8 and I knew about it but given the quality of the water I have and the explanation of why AN PH perfect series could be used in soil with no PH adjustments I gave it a try. Now I have learned and I do it the right way.
I have flushed and the girls are now resting a little. Before I go to bed I will water all of them with a quarter of nutes, some Big Bud and I will use baking soda to adjust the water. Then I am just going to see if they will heal.
If not, those rusty spots could be several things and I will just have to do some more checking.
The tallest girl is now 115 cm - I kid you not!!
Now it is just to wait, hope, maybe even pray a little.
