Brown/yellowy Spots and Stripes
THC123started grow question 4 years ago
Alright, last night I did a reservoir change. I added a fraction more nutrients to the water (.25ml per gallon). I also topped the plants. This morning I woke up and there were these brown/yellow spots and stripes on the leaves. Any idea what it’s from?
Thanks!

Hi buddy go down with the ph to 5.5 - 5.8 at hydro :-) and the ec can slowly go up to 1.2 :-)

Is that the issue though? Because the PH has stayed at 6 the whole grow and it just happened after this reservoir change.

Also to note, I PH’d the water to 5.5 before putting it in. Then in the evening I went to check the PH and it was at 6.4. I added a bit of PH Down to the reservoir (rookie move. But after all, I am a rookie and still learning) and now it’s at 6. PPM is at 450.

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer.
How do you recognize spoiled fertilizer?Week 1

leaf yellowingI have a problem with yellowing leaves. Yellowing appears immediately after germination. And it continues until harvest. I thought it was the fertilizers. Fertilizers that are old. I threw away the old fertilizers and bought new ones. But the problem still persists.

Many of my plant's fan leaves, especially lower down in the plant are turning yellow. Is this normal? I think I'm on my last couple of weeks for flowering, so I'm not sure if it's just part of the process towards the end. Should I remove them, or just leave them there?Leaves. Color - Yellow

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms.
I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day.
So please have a look and see if you know what might be happening

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.
