When leaves start to get those brown splotches it’s usually because of a PK deficiency or nutrient lockout due to ph!

Unfortunately it's pretty hard to tell under the purple light is there any chance you can get a better picture?

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?Leaves. Tips - Burnt

Forbidden runtz excess or deficiency problems autoflowerBAD WEEK! need some help here guys..
Brown / rust spots started to appear on the tips and slowly started yellowing leaves.
Im following the master advanced nutrients chart and watering 2 times a week.
Last week feed was
20 litres R/O water
80ml bloom A
80ml bloom B
40ml of every additive on the chart
20ml cal meg
30ml phup
PH adjusted 6.50
After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants.
Yesterday i watered again but cut the nutes in half.
20 litres R/O water
40ml bloom A
40ml bloom B
20ml of every additive on the chart
20ml cal meg
20ml phup
PH adjusted 6.50
I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else?
since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me.
Please any help will be appreciatedWeek 8

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?5y ago

Tip burns and some spots on the leavesI have encountered some tip burns and on a few leaves I have these rusty spots.
My first thought was CalMag deficiency?

Why does my pH keep changing in Germany? I set my water at 5.9 then it shifts 3-4 times over few hours, causing lockout if I water my plants with it, In Ireland, I never had this issue. Using Advanced Nutrients A+B, Big Bud, Overdrive. Could German water be the problem? Any fixesLeaves. Tips - Burnt
