ClydeGrowsanswered grow question 3y ago

From the looks of it, multiple issues. The edges of the leaves are curling up too. If feed made worse you know the NPK ratio is off, and/or it's too much for the plant. Flush/water with just water, until you see a bounce back (and look at new growth, not the already effected leaves as they will not recover). When you feed again, feed low, and make sure the values are the right balance for the plant at this stage.

It looks like my plant is dieing! Plants turning brown after intense watering period Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

Bud rot? Mold?My plant is a bit problematic ("quick one" Auto from RQS, outdoor balcony grow). I'm a bit worried that I have to throw it out, therefore I would like to ask for your expert opinion. :) 1. Is the "brown stuff" on the top bud "bud-rot"? 2. Are the "more intense white spots" mold?

Burn, deficiency or other?I’m completely stumped as to why my one plant is showing signs of deficiency or burn. Used the exact amount of fertilizer per plant. One plant is fine and the other looks terrible. I used a half dose of cal mag and it seems to have stopped but is not drinking or looking better.

What's causing my brown crispy leaves!?Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

help in Hydro RDWC/DWC Hello, my plants are now about 4 weeks old. The leaves droop and curl. The spots on the leaves are increasing. Is the PPM value too high? It's 1000ppm tds They grow in an RDWC system with top feed. The top feed is permanently switched on. Can that lead to problems?
