Zombie bride by ripper seeds

She is coming on quite well apart from a possible deficiency. She has been a little droopy with purple streaking up the main stem. Will have to monitor. I suspect magnesium or sulfur so may give a dose of sweet grape. Update on deficiency. After a change of base nutes to advanced nutrients sensi Coco grow and a dose of calmag she looks a lot better. She's looking good now. I have uppotted her to a 7 gal fabric pot with 70/30 Coco/perlite. I am using canna and Plagron Coco/perlite. Nutes moving forward will be advanced nutrients sensi Coco grow a&b with Shogun calmag, botanicare silica blast and house and garden roots excellurator. These are the veg nutes recipe and I've still to decide on the bloom nutes. It will be advanced nutrients sensi Coco bloom for base but not sure on the pk. May go a 14-15 for a week only about week 5 or a 0-4-4 like big bud Coco weeks 3,4+5 followed by overdrive weeks 6,7+8.
