Well there you go. Lol Often when people go to route a hydro they go that route for the benefits but neglect the negatives.
One of the negatives using hydro is how fast the pH can adjust., Unlike soil that has a buffer zone.
So you have to be careful about what you're mixing in...
You truly, you would need more information.
Are you using organix or synthetic?
you don't have to drop the pH of 6.5 when using organix the microbes will adjust the pH to the best pH the plant desires. We're trying to keep it in the 6 range.
Now from my experience and especially growing...
This is not nutrient burn, it's nutrient toxicity, you can tell by the shiny leaves, the dark color and how he leaves are drooping. "Flush" one gallon of water, per the gallon size. So if it in a 5 gallon bucket flush with 5 gallons of water.
If it was nutrient burn you just need to stop...
Well this has a technicality, the average grower is not growing over four plants.
So they don't need to brew a compost tea that takes that long or as much, to the point that molasses would hurt it.
I mean sure if you got up to 10 plants and you have to make a big batch compost tea that's that...
I noticed your leaves are tacoing. That's normally due to high CO2 or too much wind (suffocating your plant). It's hard for your plant probably breathe in CO2, if the wind is blowing too hard but on other hand too much CO2 can be toxic.
Leaves curl up, something's wrong above, leaf curl...
Plants look lovely, this is your first run but I can definitely tell you did your homework. Coco and fabric pots are basically hydroponics. Almost impossible to over water, high root aeration and super easy to flush. So that explain the growth. the big fan leaves tell me you have a pretty good...
Well that's a loaded question.
There's multiple type of enzymes that do multiple things.
I use a compost soil/peat moss mix.
I use ferminated vegetable and/or fruits fertilizer. Some enzymes make nutrients more available for the plant, some help break down sugar for the microbes.
So it also...
All I do is manifold! You get more top colas and you're able to optimize your lighting.
I'm happy you didn't take out the bottom fans leaves just yet like some people do. It's unnecessary until the top is fully cover over those leaves and they're no longer getting direct light.
Never remove an...
I find that a lot of people don't know that when you chop your plant especially whole it's technically not dead yet, it would be in some front of Half Life half dead stasis for about a week, in which it will literally act the same way as it wasn't chopped.
Think of roses in a vase with water...
