Leaves burnHi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips.
I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!Leaves. Edges burnt

First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static9mo ago

Weed doctors to the rescueDay 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏1y ago

LEAFS DYINGThe edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?Week 9

Black discolouration on leavesOkay so the problems with the black spots continue only on one plant. I tried reducing nitrogen and increased calmag to 4ml/g. I defoliated the affected leaves and sprayed with baking soda mix. 3 days later they're appearing again. If I don't get this fixed soon im gonna lose herWeek 2

Leafs on top turning slightly yellow and getting black spotsHi fellow growers,
any idea on what's happening to this plants?
All three pictures are different plants and it is spreading super fast. One plant in tent doesn't show any of the symptoms.
I already flushed them and gave them a light nutrient solution with PH 6,2Leaves. Color - Black or grey
