Grow QuestionsBrown/yellowy Spots and Stripes

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.

One of my plants fans are yellowing, spotting, pretty badly. The medium PH is 6.5, same as my other plants, but she just doesn’t seem to be liking it. I’m using nutrients, but not heavily. About a quarter teaspoon per gallon of the flora trio. It’s the mid fans not bottom or new.

The most common yellow leave will be found on the terminal stage of flower because plant will power up for flower produce rather leave grown. Leaves are most of the time a reservoir of H2O nutrients and minerals. Yellow leaves can apear on you plant at some point of grow?

Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficiencies

On the 31st day I noticed that, in both the plants, the leaves started yellowing from the bottom of the plant! For now the yellowing reached the first couple of fan leaves. You can see that in last three photos. Could be some pH issue or some over/under feeding?

Any ideas to what might be causing these leaves to yellow/die? Only reasons I can think of are nutrient lockout, having the lights too close (although I've heard with CFLs theres pretty much no such thing as too close) or possible having the heater running, or constant fan air
