Whats the problem here?

Over all she looks good but I'm noticing this on some of the leaves...
Soil...Fox Farm grow big and Advanced Nutrients Grow is what shes been fed...Epsom salt and dolomite lime was added to soil when mixed but I havent added any since

Potassium - yellow leaf edges

Plant beside her...same soil same feeding schedule...different strain...a few of the middle aged leaves are yellowish with couple rust spots...its only affected like 3leaves...not the bottom old growth and not the new tips...could this be cal mag deficiency?....I just top dressed with some dolomite lime and Epsom salt and also mixed a teaspoon of each into gallon of water and watered

What kind of soil and how far along are they?

I was actually gonna say magnesium deficiency but the other guy sounds confident

looks like one, two or all 3 .. Calcium, phosphorus & magnesium. They are only getting AN grow? is it the 2 part or 3 part?

Be careful of that DL. It does not supply nor calcium neither magnesium! It is just pH adjuster, breakdown is 2-3 years. It can only mess your medium. You are not chasing pH for soil 6,0-7,0 since you are not in soil. Your issue seems to be caused by nutrients imballance in your medium IMo...

I also thought it may have been Cal Mag def...could've been phosphorus as well...since this post I've hit em with a feeding of all three...I dont really have any actual Cal Mag specific nutes...so I thru a spoonful of epsom salts and the dolomite lime in warm water n let it dissolve then mixed with gallon of water n watered/fed...also to be sure used a drizzle of molasses in that same gallon (it has calcium and magnesium listed on the bk)

Yeah the AN has no cal mag...the FF grow big has mag...no cal...I've also used it thru veg some....I don't care much for the AN grow n bloom

Hello, that may be sub-optimal as Dolomite isnt water-solvent, but epsom very much... so u got much Mg + S, but Ca? these things need to be in ratio, otherwise there will be problems (locks)

The DL did dissolve in the water...not sure if the plants took it up tho

Here they are as of now

I think she wants more ppms...plants looks good besides the lil discoloration.
