If you refer to the plants in flowering, then I agree and the damage there is done. Right now I am more focused to understand the cause and do adjustments to the next batch or the one after. The sooner I figure this out the less pain :) Regarding the nutes, they are recommended by many people...

Adding additional 10% perlite to the mix in in my list for the next batch. Drilling hole and placing wooden pot elevators too. In terms of watering so far I've been trying to predict how much they drink and water every 48h. Top watering starting 100ml , around 0.5L in mid Veg week 4 and by the...

I will do that in the following days. If not for the run off so much at least to get some air to the bottom holes.

Not really as I never have runoff, except when the soil is very dry and some water drains through the cracks in the tray. Part of the problem is that I can not afford to have runoff as there are too many plants to empty each tray.

I am sure those additives are great and I've tried adding Mycorrhiza with no visible results. I use Rhizotonic by Canna, but still think that my issues are more general and not a matter of micro improvements. I'm sure there are people who have better results than me with just the basic nutrients...

Thank you for the input, let me bring some more info with regards to your concerns and suggestions. DLI and VPS should be on point. I run 18h in Veg under 400-500 ppfd LED which by all standards is optimum. VPD was a huge topic of research for me and I have finally set it to 70-80% humidity...

Dear fellow growers, I need your help to figure out a problem with my plants that has been following me for the last 6 grows. I am running a mid-sized operation and It is a repeating problem that I just can’t seem to understand and resolve. It all goes normal with the seedlings, they are...

Thanks, this hits both overwatering and overfeeding. Plus it reminds me to change from 22 to 20 hours of light.

Will cut foilier feed for sure.

I intentionally mentioned that they are constantly soaked. And now I realize that those cycles you suggest are actually more important (at early stage) than say the need to flush the media more often to replace oxygen, nutes and probably adjust the ph of the media.

Thanks for the reply. I also lean more towards the overfeeding case. Will follow your advice for both media feed and foilier feed. In the mean time I hope to get confirmation from more growers.

I use Canna Coco Professional - probably the best on the market (prewashed and prebuffered) and some of the pots are actually in Polagron Premium, just to make sure it is not a batch/brand issue. Hope to hear from people who have actually battled this type of issue as it seems quite common for coco.

Greetings coco growers! I've been having problems with early stage plants in coco for the past 5-6 grows so finally I decided to post as I have been running out of ideas. Plans on the pictures are in week 3, about 18 days since I places them in rootriot plugs. They are slow and some of them...

Real danger is above 10k and you have to stay for hours until you feel dizziness.

Machnak, did you find a solution to the high PH? I have the same problem and it's killing me over the past few months. Whatever I do, I can't get it under 6.5. I measure it with a Bluelab multimedia pH pen. I've tried to flush with 2x, 3x the size of the pot with no result.
