Hey DGC love the show love the knowledge. I’m growing organically in 60/40 coco perlite mix. I amend with chicken compost and kelp meal, with weekly Cal-Mag, Recharge and Mammoth P applications. Everything looks great. In flower I top-dress with Happy Frog fruit and flower. In week three of flower I start to add Bio Bud for a PK boost. I’m in week 5 of flower and am starting to see a cal-mag deficiency. Is this a lockout? Is this due to the PK boost? If so how can I avoid this in the future? Oh buy the way this is an auto flower grow, don’t know if that makes a difference. Thanks TC.
Thanks for sending the pic. It’s a bit tough to see coloring. Is the spotting brownish or pinkish purple? Looks like it’s got some brown spotting due to a lack of calcium.
They are rusty brown and got a hell of a lot worse. I did a flush yesterday. After I did some more research I was thinking it might be a Manganese toxicity. I really don’t know lol. I was adding 1 tsp. per gal. of the Bio Bud every time I watered. I think I over did it.
