| Hi JC, you should check your soil, position of plants etc, are all criticle for growing hybryd plants need good conditions to thrive. The browning inside the plant suggests a soil deficent of boron, you could try some trace elements, epsom salts and a little siliconite to help remedy your soil. A complete soil test will show you whats lacking. Try these,Good luck. Peter r. |
