Duke_Elakstarted grow question 4 years ago
It might be caused of overcompensating Water and/or to often.
Also Im RE uses last crops soiless mix as medium.
30%perlit
30%peat moss in HYDRO claypebbles
40% Coco coir
Dried for 2month before washubg and BUFFERING with cal mag.
WHAT can it be?? Doesnt look good at all?

Did you rinse and dilute the old coco?
drying actually increases concentrations.. washing won't help if the CEC have gone the opposite direction and have too much Ca/Mg bonded. You don't need to buffer when re-using.. just wash it well and go. if anything is separate, likea layer of hydroton, may want to sanitize that.
anyway, my 2 cents is it is an overabundance of one nute or another -- imbalance. Also ensure pH is 6-6.5, or whatever your ferts instruct.
Fruitgroweranswered grow question 4 years ago
The sweet spot for coco is ph 5.8. But you have some peat as well, so maybe 6-6.5? Might be a good idea to add a low dose of grow nutrients and watering less 🌱👍

When to harvest?I’m not sure when to harvest? The buds don’t seems to be getting any bigger. It’s my first grow. I’m starting to get yellowing leaves at the bottom of my plants, the buds are getting frost, but under a microscope the trichomes are all clear there’s no trace of orange.

Calmag issue? Or too much water?What is wrong with my little baby? Is it a calmag issue? Or is it just simple as too much water? Im not sure, but i just added some calmag to the soil, and hopes for the best 😳
I have grown many plants over time and have never experienced this problem before.

Burnt edges / yellowingWhat are all these burnt edges from? One of the burnt leaves is from the perimeter, so I'm not sure how it could be receiving enough light to burn. I also have a small amount of yellowing towards the bottom. That's normal during flowering if the low-light leaves die, right? Thx3 years ago

Nutrient problem??? Excess or deficiency?What do you think is the leaf issue?
Open to second opinions.
Most everything stayed the same, except:
> increased water: 2L to 3L per 7 gal of soil
> introduced a bloom booster
> increased volume of worm castings, molasses, mycrobes and ethylene to the tea
