Miracle Fruit Tree trouble shooting
So i have a miracle fruit tree thats almost 3 feet tall (from a cutting) it has produced many fruits since i have had it about 5 months ago. Over the past 3 months the new growth has stayed a light green and never matures into the dark green. The tree continues to produce fruit but i worry the continual light green leaf is a signed of health decline. I have it in a 7 gal container with a mix of perlite and peat moss. I water it with rain water with ph of about 5.5 to 6.0. I fertilize with dynimite 13-13-13 slow release. I apple a weekly dose of compost tea with liquid sea kelp and fish fert totaling NPK 6-2-2. I have had it in a shaded area on my outside covered patio since i got it. I think its also important to note that i have another miracle tree that i got at the same time that looks very healthy with dark green foliage. On the flip side this one has only fruited 2 berries in the 5 months i have had it. The healthy looking one seems to have no flower buds as apposed to the "unhealthy" looking one. Sorry for the long post but feel a vivid description would help understand the situation better. Im wondering if its not getting enough light or fert?
