Hello!
I have an auto Northern Lights 79 days and i think i have Ca deficiency.
I use orchid nutrient 3-6-8 + PK Fury from France Hydroponique.
If i flush i will get rid of the problem?
Growing medium is soil.
I don`t know the PH

Flushing won't help. It needs some cal-mag.. It won't fix the damage done but it will stop it from getting worse.

Personally, I would stop using nutrients formulated for feeding orchids.

If you have over done it with that PK Fury stuff, Flushing might help get rid of some excess nutrients in the soil. .. but then you'll need to replace it with a balanced feed.

I always think a bottle of Cal/Mag is worth having but try getting some nutes that others growing Cannabis have had success with.

^ what he said. It could be not enough food or ph lockout. I have dealt with both and it sucks.

As said the damaged leaves are done now. they will get worse and fall off sooner or later, if not treated fast enough.

If you have epsom salt or unsulphured molasses you can add that to the water for now to compensate. But get a ph meter as your water in may be too low causing lockout.

Epsom salts @ 1tbsp gal water. Spray directly on leaves. Fastest way to gat cal into a plant. However ur issues are minimal. If it was me i wouldnt fret over it.

I WOULD fret over it. if its not fixed it will spread horribly fast. within 36hrs it did twice for me.

As said 1 TBSP / gal should be good. If you have Grandma Unsulphured molasses , that has 2% calcium and mag in it which is nice.

Foliar may help fix it quicker as said, but im partial to foliar feeding as light can always burn the leaves when wet. Ive been taugh that way with my garden center that i run as my fulltime job so i dont do any foliar. Only soil feeding, but it will work as said as a foliar.

I will use right befor the lights will turn off.
I spray all the leaves of the plant? Or just the sick ones?
