The last few days I had 3 plants start not looking...

Kaboose13started grow question 6 years ago

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Hello ! After I check you ec/ppm level I can't really say that you've using an aggressive nuts schedule as 1.3 Ec is good for 34 days old vegings plants, if you give them plain water every 3 watering then it is perfect and if not then flush your medium just a bit. I bet your issue is mostly due to the tap water vs distilled water: which one is leading to the issue ? I would bet on the distilled water as the level of cal mag is 0 in it. I bet you've got a cal mag issue leading to others deficiencies. Concerning your PH fluctuation I can't actually tell you why your PH is rising but I can tell you that coco is a bad buffer so it can make Ec change while the plant are sucking nutrients , in my case (Blue dream) the Ec was going down every time until I start using organics nuts. PS : I know that Ghe floraseries often making PH rise in hydro so I bet the same is happening to you in coco. Hope it will help you 😁👍

Hi @Kaboose13! Well, you're having a nutrients-lockout. You over-fed your babies during the last weeks, and as a result you're having salts-buildup in your medium. In this scenario I would flush the medium with 50% of the container's capacity with a very light solution (at least half of what you've been giving last week, EC ~0.5), then put a tiny fan blowing onto the containers to help them dry / prevent from overwatering. The only way to get rid of those old nutrients is to flush them away with a decent amount of water. Hope this will help, keep us up-to-date and happy growing 👊

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be? I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda. Je vous remercie 🙏🌱

What is causing this Leaf discolouration overnight after a lot of tent work yesterday Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!

PH of water + nutes is 6.3. The soil is coco and pearlite. Did I give it too many nutrients? Did I overwatater?
