Athosanswered grow question 5 years ago

It's harder, but plausible.While the plant is small and untill it fills the pot, You still have to be carefull not to overwater. If you mix the coco with perlite, it helps a lot to prevent overwatering

It depends. The medium has to have enough drainage to supply plenty of oxygen to the roots. Otherwise, overwatering is still possible. If it's really humid, your plants will perspire less and drink less too, possibly leaving your medium even wetter than normal.

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.

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.

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?

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.
