Lol_You_Lookedstarted grow question a year ago
I noticed this starting this morning, the pH was 6.3 and 210 ppm. The water was about 7-10 days old. So I figure water change time?

No your pH is too high. 5.8 is for vegging. Your ppm is pretty low. I start around 500 ppm,I also run first solution 3 to 5 weeks.

Hello, I just noticed that some of my leaves are starting to have slight discoloration and some holes. See images in week 6. I don't see evidence of bugs or mildew and my fan may have been too close for the leaf with holes. I feed once a week and have switched to a high K feed.Week 6

Young leaves' tips and edges slightly turning into yellow. Also there's some lime-green colouring in young leaf veins and single orange spot in an older fan leaf.
I'm not sure these are some kind of nutrient burn or because of cal-mag or any other micro deficiency. Any idea?Week 4

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.Week 2

I've been getting some of the burnt tips as a result of the watering with nutes. The nute mixture is already half the recommended dose. I've tested my runoff pH and its about 4 or 5 even though I've been pHing my water to be around 7 and no lower than 6. Anyone have any tips?Week 8

Help guys! What is wrong this time? Is it the high EC? I was giving Calmag to prevent any problems but I am using tap water. I water them manually, nutes - no nutes - nutes - no nutes and so on. Any advice how to get a decent outcome this time? Not every leaf has this problemWeek 10

On my NLxBB there appears to be rust spots developing on both sets of the first true leaves, i've only fed nutrients once on Day 10 and that was at quarter strength.
Not sure if this is a sign of overwatering or if I need to start feeding with Cal-Mag more regularly.Week 2

Hello,
There are copper coloured spots on many leaves on one plant. I have tried Foliar spraying with magnesium. But it doesn’t seem to help. There is a bit of purple in the stems as well. I gave them some cal-mag, but still there. A few fungus nats. Gave nematodes 2 days ago.Week 11

Taken a few pics of one of the affected leaves.
Thinking potassium deficiency but not 100% sure
Was away for best part of a week & had someone else watering them, just plain water (may of spilt on leaves?)
Leaves seem crisp to touch as well as the yellow/brown colouring.Week 5

I'm a little bit worried about recent signs of yellowing leaf tips on upper/newer growth which as far as I know are usually signs of nutrient burnt, right?
But this is definitely not the case as I didn't feed them with any nut's yet...any ideas, please? See last 2 picts of week 6Week 6
