Girls are very sick :(

[Christine20]

Hey guys,

We are dealing with an issue and we are wondering if you can give us some help: we use a drip growing system, with a single reservoir for all the girls. We have a total number of 24 plants, which grow in pebbles. They ve grown normally for the first month and a half, but now they started to have their leaf tips burnt and more than that some of the leaves started to get yellow and fell.




All these came after a process of flush we did using Canna Flush. In the flush process we followed the next steps:

1. We let Canna Flush make its effect for a day

2. The next day we watered only with reverse osmosis whater, regulating at the same time the ph of the water

3. After that we went on with normal feeding

We don t konw if this was the problem or something else.




The water ph is between 5.6 - 6.2. The lamps are at 400w/4 plants. They don t seem to grow and their leaves are really sad. Something goes wrong and we noticed some white spots on the pebbles, white spots caused by the salt. They receive 15minutes of feeding once every 3 hours.




Every opinion and solution is really appreciated 🤞

To me it looks like they're not getting enough light because it's the lower leaves. Also, in the first picture, it looks like that one may not be getting enough water. May need more pictures of the whole plant to get better answers if you can.

you have issues in the root zone whats the ph coming out from the plant how about ppm ,can you look at your roots

Thank you for you pertinent answer guys. Indeed i had some ups and downs with the ph. Do you think the problem is irremediable ? The EC whas around 1.0.

Magnesium deficiency is causing your leaf color issue.
