Hi there,

I recently got back into growing after some years. Buddy brought over 9 healthy girls. Issues showing up on all 3 Oak Town Crippler and one Ice Cream Cake.

Was warned of CaMg def issues with the OTK.

Just flipped to 12/12 two days ago because they got so big.

Media: coco op amended and buffered
Nutes: biobizz fish mix
Biobizz bio grow
Biobizz bio bloom
Biobizz top max
Growmore kelp extract
Shot of super thrive at potup

Used 1 ml per liter fish mix and same dose kelp through a couple weeks of veg

Switched to 1/2ml/l of bio grow
1 ml/l bio bloom
1/2 ml/l top max
1/2 ml/l kelp
1 ml/l molasses
And full 5ml/l calmag plus for first flowering watering

Used 3ml/l calmag plus after 1 plain watering in veg, that plain h20 I think caused this to start.

I use well water filtered with poly and charcoal filter.

Water fed at 70deg and varying 5.5-6.5 ph. Runoff last round was 5.6-6.02 depending on the plant.

Growing under cob led's.

I hot two with 2ml/l calmag and 1 ml/l foliar this morning. Hoping I didn't go overboard.

If anyone sees glaring holes or messups in my program pleaselet me know. It's been a good six years since I've grown and I have brain damage that plays hell on my memory.

Wondering if I should spray other two or let them sit. Or sweater with more CaMg? Don't want toxicity but they have been sliding on this slopefor a week or so. Be to coco and open to inputs. Ty.

If you're now adding a calmag supplement then give it chance to work, your new growth looks ok n doesn't seem to have any calmag symptoms, remember to water until run off in coco about 20%, also water everyday in coco for best results
