I would say overwatering and a humidity that is too low. Watch out with those low temps, can really stunt your grow. Which soil are you using anyway? It seems to me that it has also been fertilized a bit too strongly. Light mix soil is best for seedlings.

It doesn't look overly concerning but I'd say its over watering if anything. Young plants have small roots and don't need watered as often or as much as more mature plants. Wait until your pot is obviously lighter when you pick it up before you water again and see if it doesn't straighten back up for you.

Leaves are turning into dark green with a plastic-like texture I have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

First timer seedling worries.First time grower, is this normal for a seedling? I'm currently on day 3 and noticed these guys have some dark curling leaves. Is this caused by over/underwatering? A light issue? Or am I just over worried? Soils feels moist. They are in Tupur, lightly buffered, in 1gal growbags.

Leave Tips Yellow and Brown on New Growth The leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.
