Deficiency/Light Stress Issues
What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Leaf issues with 3 Pineapple Express Autos - is it burn or deficiency?
All 3 plants are having issues to the lower leaves. They are dried and brown blotches, brown edges of the leaves, leaves drooping off and curling down and brown. They switched to Canna Terra Flora two weeks ago - is this a over feed or deficiency?

Mancha en hoja
A que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)

Brown patches on leaves, thought it was calcium deficiency symptoms.
Having problems with brown patches, (see last 3 pics week 10), a quick google and I went with adding more CalMag but it's got worse the further into flowering I go, the farthest behind plant has least, furthest ahead is worst, any ideas?, many thanks in advance :)
