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!

MadeInGermany 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.

Overwatered cubes in hydro? Too close to the sun? or effect of having add Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
