Leaves sagging slightly in DWC. Opinions?

mkweed · Dec 13, 2019

TLDR: Leaves sagging slightly, also what opinions if i'm doing anything wrong.

Hello, first time growing. Just wanted to get an opinion on how im doing and see if I'm doing anything wrong
My 2 plants are sagging since I have transferred them to our DWC. They did show a little bit of sagging before I transferred them but they have sagged a little more.
Some of the problems I think it could be:

Light Distance - The plant is 1200 watts (Equivcoal 600 watts HPS), Its currently ~33 inches away from the light
Too much water in the bucket. I filled the water for both roughly about a quarter of the way up the net pot.
Nutrients - I added Advanced Nutrients Grow and Micro, both at ~19 mL, and Zyme ~4.5 mL (is this too little or too much for a 5 gallon?)
Ive been using Vinegar and Lemon to bring the pH down and baking soda to bring it back up. Sometimes when I noticed the pH goes up, i adjust it every night before bed
Temperature, While the nights, mornings and evenings are fine, around 12 to 6 the temperature can get a little hot in there.

The air stones are producing a good amount of bubbles so I think were ok with them.
Ive noticed they are growing leaves however one of my strains, Purple Queen, the leaves are coming out closer together and at different angles, not as uniform as my other plant (White Widow)
Here are some pics:

Ill take any suggestions and information. Can provide more information if needed.

If this thread is in the wrong sub forum, let me know!

They don't look that saggy to me. Im growing purple queen right now and it does get some pretty big, heavy leaves when its older.

Read Aqua Man's thread about VPD, it will help you with light height based on leaf temps.

For the water level, you want it to stay between 1-3 inches below the net pot. I would also recommend placing your growing medium about one layer of hydroton (half inch) from the bottom of the net pot, buried deep in the pebbles.

First , get a ppm/ec meter. Start your plants with a low ppm and see how they respond. If the nutrient ratio in the reservoir rises then you need to feed them less, if it drops then they want more.

Daily ph checks and adjusting when needed is a good practice. I've only ever used GH's and Nectar for the God's ph up/down so I can't really comment about using vinegar, lemon, or baking soda.

The vpd thread I mentioned will be useful here, it will show you where your ambient temps and humidity need to be. If you have trouble adjusting your temps into spec, provide some more pictures and details about the setup and you will get some good advice.

Appreciate it. Will look into all this.
