Its a white widow auto around week 4 of flower getting brown spots it seems to be only on the top leaves I am thinking its a calcium problem or a ph problem could be both been watering with ph at 6.0 and no calmag for a month or so. Just watered with calmag and ph at 6.0- 2 days ago hoping that will help should I up my ph to 6.5 and give more calmag at next watering or is this something else altogether ..

I would think this is a nutrient deficiency and not ph related. When I have random deficiency issues growing in dirt I just fertilize with Miracle Grow (20-20-20) a couple times and it usually clears up.-
I would never use what Kevin77 uses to fix a flowering MJ plant wrong NPK

When looking at any deficiency the first thing to check is the PH. Go to the link and look it up, follow the "read more" when you find the one that matches yours.
Edit, BTW the spots wont heal, watch the new growth.Comment

If I had to guess i say the ph in the root zone is off causing lockout. Check you run off PH.
IMO, adding 20-20-20 sounds like a recipe for disaster. Personally I dont think that plant could handle it but that's just me.5x5 Gorilla tent

flush with properly PH'd water. Assuming its soil in a fabric pot just water thoroughly and make sure the pot isn't sitting in run off water as it will get reabsorbed in a fabric pot. If it is a lockout of nutrients then it could be your PH meter or however you test your water is slightly off so check to make sure the reading is fairly accurate.
wait about a week and see if it stabilizes. The new growth should look fine but the affected leaves will not return to a normal state. Adding more nutrients should wait until you have determined the cause.
Personally I have grown White Widow auto indoors in soil with fabric pots without using a calMag supplement and they did just fine. All I used was General Hydroponics Flora trio.I hope there is an afterlife...there are a lot of friends and family I'd like to see again, one day.Comment

If you're growing in soil then the pH of 6.0 is way wrong. https://www.growweedeasy.com/wp-cont...-marijuana.jpg the calcium may be in the soil but the plant can't access it.TENT: Cool Grow 3x3x6 LIGHT: M-H TSW2000

Here’s a great chart to get to know.
The pH needs to be at 6.2+ for calcium uptake.There are 3 things you must check everyday when growing in hydro:
1) Water level (How much h2o is she drinking in 24hrs)
2) pH level (change over 24hrs)
3) ppm/EC level (How much food is she eating in 24hrs)Comment
