Can you fill out the troubleshooting form?
What brand of potting soil?
Did you rinse the sand before use by any chance (this is kinda maybe not that important; I'm not sure how salty different grades of sand may or may not be)?
What is the pot size (canoed over leaves is indicative of rootbound in some cases)?
How much superphosphate did you add to the soil and when?
That plant looks... hungry. It is either underfed or actually locked out.
I've never used Earth Juice. If my plants looked like that this is the list of what I would do:
1) Check the pH of the soil runoff, as well as its color. I've TASTED the runoff before to check for saltiness since I don't have an EC meter, lol...
2) Be certain that the pot size is adequate.
3) Do a foliar feed with the 'Micro' from the GH 3-part... it has N plus micros in it and your plant looks like it needs BOTH.
4) Wait a couple days to see if greening occurs.
5) When the soil dries out enough to do a re-pot, do it, and I think this time you might want to go a little lighter on the worm poopies and skip the superphosphate.

Edit: High temps will also cause those symptoms. How high the temps have to be before symptoms are visible is strain dependent.
stinkyattic Reviewed by stinkyattic on . Yellowing leaves a problem? Brownish/Purple stems? Well this is about my Romulan mostly. Its leaves have been a yellow green color for as long as I have had it in bloom, approx. 3-4 weeks. I had noticed it's stems and branches turning purple. I did some searching and saw that it was either stress or natural. I water just as I do the rest of my plants and the pot size is adequate. As faras the leaves, some are starting to curl and fall off, i was thinkin it may be lack of phosphate, but I want to be sure what's going on. Hope to hear what the Rating: 5
