" weeks into flowering and this is happening

ive orderd calmag and AN Revive many people says its calcium and magnesium def and its pretty common
so ive flushed them with water just now on the ph scale of 6.2 il let them dry out and then use calmag or revive what would work best ? thanks guys .. recently the tips have browned

What substrate are you growing in? Coco?

If so did you wash well?
If you did wash well, did you precharge with calmag before planting?

I used to mess with coco, but honestly I just can't be bothered with it anymore, I reverted to miracle gro

im using coco coir ive not calmag'd them yet im waiting on it being deliverd ther in 12 litre pots 2 week into flowering my mate says its calcium magnesium def so i orderd that callmag and people have says AN Revive is also good ive never had this before with big budda blue cheese this is a first time for the yellowing and browning bigtime pain in the ass but still plenty of time to save them i want them to have a brilliant flowering peroid and a shit hot smoke h

forgot to add mate the leaves have got a bit worse since that pic browning tips not on all leaves only some

You"ll be ok. I've finished crops that didn't look half as good as yours. Just go easy on your nutes until you can get a hold of the cal mag. Calcium and magnesium play a role in nutrient uptake and transport, so don't try to compensate, you"ll end up locking out your nutes. No fun haha been there a few times.

On your next grow, mix up about 20-30ml of cal mag per gallon, and let the coco soak in it, that should halt the mg deficiencies.

Just out of curiosity are you feeding every watering or flushing at all? I had a problem over nuting and over watering at first

so do you think not to worry much and wait till calmag comes and add that ? eny suggestions how much and stuff ? will i add my nutes with it or just water and callmag

somebudy says to me advanced nutrients revive is just as good as calmag

Im no pro, but that doesnt look like a cal/mag def to me.

I would speculate a Sulfur def since u said the tips are turning brown. Nitro def was my first guess but after looking at this image, im leaning twards sulfur.
