Hi! You probably want to check on the pH of your drain at first.. :) If it's too low, there could be lots of deficiency signs but caused by low pH. All the best!!

Brown spots
brown spots began to appear, could this be due to watering with PH 6.0, maybe too little and calcium is not absorbed? PH of water with each watering 6.0

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 static

Leaf necrosis
What's going on with mk Ultra? It gets Neem every 2-3 days, and I have tried to keep pH down to 6. This has been going on since I got the clone, and it continues to happen. The pink kush (last pic) has a few similar spots. Lights are 50cm above.

Ongoing brown and yellow patches forming in week 6 of flower
I've also noticed today a couple leaves looked wet, so tried to wipe it off but that did nothing. I took 2 pictures of the same leaf at slightly different angles to see the shine. It's only the skunk effected (closed similar question prematurely in skunks diary)
