Yes but a soil ph check would be my first thing to look at. Make sure you are in range. Nitrogen level is a little heavy.

Root rot?
I feel I made a huge mistake. The last two weeks I suspended the top bloom fertilizer and star to give a considerable amount of organic molasses (at EC=1.4). The soil turn compacted, and leaves begin to yellowing. Is the plant showing signs of root rot? What should I do? Help!!

Your opinion?
Today flushing the wedding cake i was thinking that the problem was an excess of nutrients, but instead water was quite clean, around 1100ppm at the first drain, after several flushes water is now on 600ppm. I also raised the lights.. I still do not understand 🤔

can you see the plant on the top right? I've read she could be a albino? She has been bright green/yellow since birth and has been grown in same enviroment etc as others? Also had no nutrients

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?

Should I be worried with yellow and brown tipped leaves? Will it affect quality or yield? Can I correct this? With my nutes I used sturdy stalk and Ph’d water 6.3 and I feel it could be the lights but it also started from over feeding Nutes. B4RNS called it!
