you could use lemon juice, i've used it. I wouldn't use it again...if you can get ahold of ph down do so. If you can't perhaps you can get some reverse osmosis water or distilled water to water them with. They are ph balanced. If you continue to use this kind of water you will need a cal-mag supplement.
Bree1978 Reviewed by Bree1978 on . My dear sensi*...orange speckles?? Hi guys, I got some free seeds which i believe to be sensi star and have planted two, one of the plants is extremely healthy, the other, is growing well but has orange speckles on it leaves, mainly lower to mid but it looks like they are moving upwards. Im using 2x20w fluorescent bulbs temp is about 76 degrees f and both plants are kept in exactly the same conditions/soil. See the pics, the orange seems to be mainly on the veins of the leaves, can anyone give me a diagnosis?? nb the last pic Rating: 5
