Calcium def? Phosphorous? Potassium excess? Boron?

I’m growing 3 NL Auto Fem , by Growers Choice. I had the same problem right before she started to Bloom. I Have one indoors ( fox farm nites) and 2 outside ( organic )wanted to see the difference. I did give my indoor Girl a shot of cal mag thought the same thing, spots gone Buds arrived. This is my first indoor grow so I am learning as I go. Check out my NL and the pic I have of my leaf before and after might help ✌️🌱✌️ Other wise your plant is #dope I will be following you to see how she turns out #peace

Hi inner cal / may add before the nutrients Best if you have osmosis water and mix the stale water for 24 hours (after 24 hours the chlorine has evaporated somewhat) to an Ec value of 0.2. Then add Cal / Mag until the Ec is 0.4. This is your source of water

could be boron def? if your nutrients aren't complete, you need supplements. bad products require supplements. i had a calcium/magnesium deficiency 2 different times. 1st time in soil while using trashy FF products. 2nd time when i switched to coco and used a cheap, ill-prepared brick that falsely advertised. if cal-mag is all you have to add, which seems not to be the case, look for a more compelte feed. otherwise, they'll always have somethign they can market to you... that you need and should have been in the first product you bought in the first place.

@MadeInGermany Hi, thanks the kindness :D I do add 1ml/L of cal-mag from GHE, but I haven't testes my EC before adding it. By the way, should I add Cal-Mag before or after the other nutrients?

Hey, I wouldn't worry so much for now ;-). your plants look great and your environment is perfect 😍🙏🏻. How much cal / mag do you add to that, how much does the ec increase afterwards?
