I agree with BF. First thing to check. Also, some strains require more Cal/Mag.

looks like calcium def and heat stress

Wow never got the notifications on the post. I use a small boy declorinator and runnin gh calmag also. I fill my res then add mills nutrients vitilize product its like fasilator then add calmag,hydrogaurd, heavys a&b sorry about the late reply how much cal should i use im not seeing any issues now week 3 in flower

Looks like mag def to me.

What kinda water are you using?

Small boy declorinator it happens every time wen the plants get to teen stage then they grow out of it diff strains dont do it some do

What happens when you don't use it? Ilike is there a reason you started it?

Alot of ppl said i should use it over my tap as it strips the water of clorine i use my tap sometimes and dont see any difference in ph fluctations or anything

Here's what i do.

I (at any given time) have 2-3 gallons of tap water sitting with the cap off. Every day I well put the call on, give them a heavy shake and take the cap off and let them sit again.

Before I use the gallon I will put the water in the bucket that I mix my nutes and throw an air stone in and let that bubble for a hour or whatever (I can lose track of time).

Then mix my nutes, pour it all back in my jug, feed my plants and call it a day.

I know it may sound like a lot of work or waste of time but I use to use that dechlorination stuff and found it was a waste of money.
