I'm still having some plant problems...

This is my ak48. About 7 weeks old now. There's still some orangish color on the fan leaves. They were switched into flower today. Wanted to know if it would be safe to use " X Nutrients CalMagX" any suggestions?

It looks like nutrient burn to me but could be wrong. It is a common thing to do. Back off the nutes a bit ?

what is your medium and what ph are you feeding them at? I'm guessing over feeding causing low ph in the soil = low nutrient uptake.

too much fert already.

I haven't been giving them barely any nutrients. The soil I've been using from the begin is organic miracle grow, which I was told isn't so good, however I thought maybe this could be from something else. When I posted pics about 3 weeks ago the plants only had a couple of spots on the leaves and most of the responses I got were about people saying is looked like a calcium magnesium def.so bought calmagx from xnutrients ..spayed leaves with it in a spray bottle ..yesterday .5ml in a gallon of water with a ph of 6.5

When you switched to flower did you start using flowering nutes ?

no not yet.was gonna wait a week to do so

Just wondering, good shout, maybe use veg nutes for two weeks. How big is your pot as she maybe root bound ?

three gallons and from top of soil to top of plant is 2 ft..have 7 gallon pots should i switch them..and how could i check if there root bound bc def could be possible

I would check by letting it dry out and lift it out gently. I would def repot as if root bound she will be getting deficient due to not being able to uptake nutes. Give her more root space and see how she goes with new soil

ok and put more miracle grow or can i mix it with fox farm ocean forrest

I would be hold off on the MG at the moment. I would go with fresh soil first, let it take from the soil all it needs then feed with MG when you notice it needs feeding again... ? I don't know FFOF but any good bag of soil/compost should do...! When you repot, break up the rootball some but be gentle. Ease her into her knew home gently...

So this is the one with the most damage to the leaves. I just re-potted in a 7gallon.

Def looks like she needs that new pot, break the rootball up a bit, be gentle, re-pot and water away, give her a good soaking... Nice looking girlie by the way, happy growing & enjoy your christmas....!

You don't need cal mag unless you have RO water, are you letting the pots sit in the runoff slurry?

MG soil tends to be too hot for this plant, especially when it's young. It's over fert. cal mag won't help. repotting into more MG soil won't help. there will continue to be browning of the leaves, but maybe the plant will survive. ffof is a better soil for this kind of plant. it's made for this kind of plant.

No, water both the medium it is currently in and water the tranplant medium and then place the plant in the new container. Be sure to trim the roots back... Superthrive is supposed to help prevent transplant shock 10 drops to a gallon or soo.

I don't water after transplant as long as the soil is moist.

MiracleGro's organic choice shouldn't be too bad if you add 40% perlite. It's the only one I would consider. The others are either too hot with nutrients, or contain vermiculate "moisture control" which is typically unwanted unless you grow under the radiant heat of HID.

I think the lack of perlite in that soil contributes to the overwatering symptoms people are seeing. I think your foliar feeding has created the leaf condition you see now.
