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.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

Nitrogen deficit?The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each). 3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves. I suspect this could be light burn or nutrient related. Any ideas? Pls help

Upper leaves are yellow and not smooth I noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?
