Ask a Grow Question

[dannogrooz]

Hi everyone. First grow in coco (70/30 coco/perlite) and first run with autopots (sorry Scotty lol). Using canna coco nutrients, cal mag, and have very hard StL tap water. Got a deficiency and need advice from someone with much more experience than me. They are autoflowers. Thank you everyone. I am guessing mag or sulphur but could sure use some advice.

I would Give them some water with epsom salts to boost the magnesium it’s looking like a magnesium deficiency to me!

Probably too high of a calcium to magnesium ratio. Too much calcium is an issue. Cut out the cal-mag and see if it improves. If Interveinal chlorosis (magnesium issue) continues, add 1 tsp of Epsom salt per gallon of water to your base nutrients (Canna).

Magnesium deficiency. Mix in some epsom salt and it will green back up.

The inter veinal chlorosis looks like a magnisium deficeincy to me. Either a calcium magneseum inbalance or a lack of magneseum. If the later add a tbl spoon of epsum salt per gal of water.
