Cal mag ?

10-20-2023, 10:48 AM

I have a nutrient burn problem I'm working on. I flushed the plants with a garden hose. Soil ph tester shows 7, waiting on water test kit. I noticed that when reading the label on calmag , some show 1-0-0 and some show 3-0-0. I was able to get "Earth Juice" 3-0-0 locally. I'm having trouble understanding the directions so I'm mixing 1/2 tsp per gal, well water. Starting with 10 oz per day, per plant. No nutes right now, only water. Still reading and learning, so am I on the right track? Plants about 3 mo. old.

8'x12' indoor/outdoor grow room
3'x5 dark room
2x12" exhaust fans
30"x36" intake filter
3x180w 4' led lights
std.potting soil w perlite added
Fox farm trio,cal/mag etc.

Do you have a pic of the plant and one of the nute burn?

Edit. I just went to their website and found a heap of feed charts. No idea which product your giving it but ½ a tsp per gallon was about right on the 8 or so additive products that it listed.

These plants app.3 mo. old. About 2 wks ago the leaves started curling. I thought it was the light to close. As it got worse I kept on reading. Took them out side and flushed them good. As you can see the new growth is looking good. I keep cutting off dying leaves. Been using 12-4-16, 10 ozs. twice a week. Now holding back.

I'm not sure I'd describe that as a nute burn problem. You have clam shelling, tips curling up, tips curling down, problems with leaf margins curling in and leaf die off in all those areas and mostly up top on new growth. Heat is not an issue and I'm guessing light is not too close.
Root issue caused by not sure but I'd start with pH and look closely at PK possible issue. I don't think you have a caltmag issue but I would keep feeding them cal/mag anyway.
