This one Sea?No cool charts, but Quantum9 posted a fascinating paper in a thread started by Capulator on light spectrum affecting nutrient uptake/utilization. I should have bookmarked that thread, now I can't even remember the title.
first 2 weeks 400 MH, DNF gro ab. then when I change to the 600w HPS the leaves turn a faded lime green top to bottom. the tops burn and curl ..... I have the light now 18" away from the tops.
the plants to the outside of the light (further away ) fair better.
At the same time I also change to DNF gro ab and bloom fortifier at about 1200ppm, 6.0ph runoff, alternated with teas at about 800ppm heavy on molasses. same ph.
am I underfeeding? this never happened with the MH all the way through flowering.....
I think you nailed it there. I already have been applying epsom salt in their feeding/watering (About a tablespoon per liter) about 4 +/- days ago. I'll try the foliar treatment as recommended by you thanks! Also after reviewing the list of nutrients necessary I noticed Ca a few days ago and sadly haven't addressed it. Is that also apparent? What would be the simplest way to supply ca to it? Also yes you're correct during the period of growth at around their 4th week I was trying to compensate by giving them more feeding but went too overboard with it. Now I'm about half of the recommended feeding for canna for now. Will focus on the ca/mg like you said and keep the N P K feeding at a lower amount for now (About half of what is recommended on bottle atm).
Edit: Are there any other necessary nutrients I would need like zinc? Iron? Just don't want to do the same thing I did to Ca.
Holy shit! A full tablespoon per liter, not gallon, not teaspoon? Oh my goodness, you can back off of that, a whole lot. A WHOLE lot. All that Mg (there's also more sulfur in magnesium sulfate than magnesium) will block other minerals, it's antagonistic to them.I think you nailed it there.
