has anyone used this before? its NPK value is abit weird - 10.6 -1.5 - 1.4, dont reckon thats any use as ferts but im poor and cant afford any decent ones so if anyones had experience comments would be apprecciated! also, i overwatered due to inexperience and some of the lower leaves on one plant have gone abit yellow, when the soil dries out will this go away or should i prune it? P.S i just realised i posted this in the wrong section...sorry...
