As I understand it HYdro PH with coco is 5.5 to 6.0
5.5 to 5.8 is golden Thats the message from others and books. I water my mother plants by hand watering. They are under a T5 veg lamp. I also use clerex every week by topical watering to flush the salts. As far a Cal mag I never use it. To 20 gal on an eb and flow I use the following:IN veg
5 oz base, 5 0z grow 3 oz sweet, 3 oz liquid Karma, 3 oz hygrozyme
iIn flowering;
5 0z base, 5 0z bloom, 3 karma, 3 sweet, 3 oz hygrozyme 5oz. blast off,
5 oz big bud, use big bud for the first 4 weeks of bloom then subsistute 5oz of overdrive the last 4 weeks, flush with clearx every week as I change my water every 7 to 10 days. ph 5.8 I use purified water. The last week I run clearx for 3 days then just plain water with 6 oz of molassas for about a week. Perfection!!!
iRayone Reviewed by iRayone on . Handwatering Coco Question..... Justa quick question for those of you who hand water CoCO... I understand Coco is kinda a HydroPonic Medium. DOes this mean that the Ph should be in the lower levels 5.5 - 6.2 like ina hydroponic Setup? Or because Im using it ina hand watering Method should my Ph levels be more like soil Levels. 6.2 - 7Ph ? I ran tap water 7.4Ph through my Coco Coir and my Ph was 6.7Ph Runoff. I think this should work well eh? Rating: 5
