Hey guys I've been running the Head/Rez 6/9 GH micro/bloom mix in Canna Coco for a while now with consistently great results until this week a flower room of 8 plants all in 2.5 gal coco pots handwatered twice daily are looking seriously hungry. I suspect magnesium deficiency. The other problem is these are newer strains to me. They are G13, Williams Wonder, LA Confidential and AK47. All show the same symptoms. In addition to the micro/bloom they get fed half a gram epsom salt per gallon plus some silica blast and that's all. Except I gave them 10ml bushmaster kangaroots root drench a couple weeks ago. They are day 12 flower.
How long has this problem been going on? About a week

If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?
Are you using water from a water softener?no
Has plant been recently pruned, cloned off of or pinchedsome where recently supercropped, but the non-supercropped ones have the exact same problem
Have any pest chemicals been used? If so, What and When?sprayed with forbid, and watered with bayer advanced citrus/vegetable imidicloprid before going into flowering about 2 weeks ago, also use mosquito drops
