Since the beginning I have had problems with leaves turning light green in between the veins, then slowly turning brown and crispy along the edges. This will work its way in towards the middle of the leaf and eventually the whole leaf will die. It has affected all plants, and I've never been able to solve it.
- Tends to affect the larger more prominent leaves, with the older ones slowly exhibiting the problem more. New growth will tend to be healthy green, then start displaying the problem as it ages.
- DWC buckets
- currently in week 3 flower, all buds growing normal
- Spider farmer 4000 light
- Emerald Harvest 3 part nutrients + calmag + emerald goddess + king kola (I add only a tiny amount of the last two to keep EC levels down.
- Feeding between 1.2-1.4 ec.
- At 1.4 ec the ec levels will rise as the plant drinks, so I add fresh water to bring it back down. Using bluelabs truncheon.
- Ph varying between 5.7-6.2. Using bluelabs meter, all calibrated.
- Plants drinking lots, litres per day per plant.
- Using a small amount of heisenberg tea to keep roots healthy.
- Temps around 26c (79f) during lights on
- Humidity around 50% during lights on
- Roots all look good, no sign of rot.
So the nutrient solution tends onto the hot side, and the ec levels rise when they drink, but I water it back down to keep it around the 1.3ec level.
Our water is super soft, sometimes it wont even register anything on the bluelabs truncheon. So I add calmag to bring it to 0.4ec, then add nutes on top. It's pumped up from deep undergroung.
I've raised the lights, which doesn't seem to stop it. One plant which is way off to the side has it the worst. So I thought it cant be light burn.
You wisdom would be appreciated. As of yet I cannot solve it.
