BananaPurplePunch Problems

Hello Gerbst, Yes, I can see some nutrient burning and some nutrient lockouts. My advice would be to flush with the pot volume in water. Because you want to flush out the nutrient salts that have been building up inside your soil. Because of these nutrient salts the pH and EC are out of range inside the soil. So you want to use a nutrient solution with pH 6.5 and 50% from the nutrients that you are using now. Let the top 2 inches (5 cm) from the soil dry out completely before watering again. After you have done this you can continue feeding like you did but 75% from the previous given nutrient will be enough. And always give till 20% runoff to prevent nutrient salts building up again. Happy Growing Buddy!

Hey mate, The yellowing on new growth could be a wrong pH, so they cant take the feeding in. Its upwards your plant maybe, its light. The other signs could be a Cal-Mag definciecy, but dont think so, you could add those to your feedingshedule. Knowing what you feed before im sure its no P-deficiency. If you feed 2/3 of the amount of nutrients, you can be sure it wont get worse, because of any overfeeding. It also could be from overfeeding still, to stop it completly now you would have to flush your plant. and then give a regulated feed. Otherwise it will slightly go on for few days. So check the pH of your feeding, It should be between 6-7 or slightly off. Also check the PPFD. And you could flush your plants on next watering. Good luck mate

i had one cola get a bit taller and started to get bleached. I put one of those mesh bags for supermarket produce or to put around outdoor plants during a frost etc... it attenuated the light for that 1 cola and still allowed proper airflow to it. I did remove it before lights out, but probably didn't have to because it did allow airflow, but still reduced airflow, so it was just to be safe. Anyway, something like this allos you to protect an oddball cola that's too tall without sacrificing light to the rest of the canopy. If you deduce that it is light related....

is that cola taller than the rest? if so might be light-related. Just burning through nutes faster than it can handle, if so. Seems like it's mostly localized to that one cola, too. Some minor tip burn elsewhere. If anything looks slightly overfed elsewhere across canopy. if in soilless/hydro this is easy to figure out and much more of a guessing game in soil.
