purple leave stem/ dropping leaves

hey to me that looks like what happend to me it was cal/mag deficiency exactly same droopy and red leaves/stem
foliar feeding helps fastest because the plants only uptake of cal/mag is at PH 6.2.-6.5 range
goodluck buddy

is that true, in hydro?? i try to keep my ph at 5.6-6.0 in rockwool cubes.. if that is true my plants would not look so healthy,, they would definatly be lacking cal/mag.. it may even be available in my nutrients just not be taken up because of ph... ive heard ph fluctuation from 5.6-6.3 is ok in hydro, but i keep it below 6 almost always...
so id be better keeping my ph at 5.9-6,3?? id worry because anything above 6.3 is bad in hydro...

ahh sorry brother maybe i didnt explain it all to well normaly tap water have calcium in it already and other stuff
like my tap water is very low on calmag thats why i get the deficiency at every grow so i need to add calmag
to keep it in ballance but like i have learned maybe im wrong is that calcium is only taken up in higher PH value
so what your gone do is not change your reservoir to 6.3 but instead have a spray bottle with calmag in it and have that on the 6.3ph range your reservoir stays between 5.6-6.0
thats how i bin doing it for the past 3 years if bin growing so sorry for not explaining it firsthand my bad

its all good.. i printed out the pics of deficiencies on page 1 and hung them in my room to reference any deficiencies or whatever..that will make identifying problems much easier.. i normally only foiliar feed in clone stage, after that i would get burn from the lights and i never go in my rooms after lights out..
