So new room, new area, new set up, gone through all the motions and corrected many problems a new set up brings! Hopefully my final problem (probably not) I’ve had high humidity, which I didn’t realise, sometimes high as 88% - but it’s been above 70% a lot of the time. So I’m showing a definite sign of Mag deficiency, medium is coco. Now I have the humidity under control, so shall I wait a week or so before I change my nutes or add Cal-Mag. By the way not all plants are effected as bad as the picture, some only very minor. Thus making me think it’s a definency in the Coco rather then humidity causing it.. I still have a little cupping/canoe’ing of the leaves but I reckon this must have been a high humidity issue, but we will find out in the next few days I guess! What are your thoughts? Also, my PH in the feed, likes to rise, I will bring it down to 5.7/8 before feed but is this possibly causing a problem within in the Coco? I have read you need to supplement Coco with Cal-Mag, however using advanced nutrients and they came you don’t need to as their mix is perfect.. Pictures below! All opinions welcome and will be helpful!
