phosphorous or magnesium deficiency

How much water are your plants drinking? Once I know the ideal ppm, I like to stay consistent with that until I notice a change. Ex. If you're range is 1000ppm, currently at 600ish, plants drinking and ph is rising, then I would add a nute mix to my add back to bring it back to 1000 or slightly higher. You'll have to learn nute portions to know what that amount would be. That's what I do and it works well.
Ok but when I try that... my ppms start to go up and I have to dump the res and start over with fresh nutrient solution
 
Lol... yea i started some shit unintentionally I guess... she's definitely grown. I switched to the Lucas formula but she's still got purpling stems and leaves slowly yellowing. All in all she's growing pretty quick as far as I can tell so I'm just gonna cowboy it and put her in bloom.... wish me (and her) luck! Lol

I know she looks like shit but this is my 1st time doing dwc and scrog...i was setup for failure from the start so hopefully the next one will be better.

Don't hope. Know your next run will be better. Mindset is half the battle, patience is the other half.

When you get into your head that you're going to do better next time, you will.

When you question your ability, every aspect of the grow begs for questions. If you are confident, you'll do better.

Thanks man! That's great advice! And you are absolutely right...i know I'll do better! Just wish I would've known then what I know now. Lol

I've been growing indoors for over eight years, outdoors for nearly 30.

Way I look at things is that there's always more to learn. If I'm not learning, I'm stagnant. That said, that doesn't mean I have to implement everything new I learn. The longer you grow, the more you'll be able to filter out as nonsense so you can focus on what matters.

Don't believe everything you read, except if the plants are writing the story for you. Let them dictate what needs to be done.
 
Yea..i learned that growing in soil... never really had any problems with it tho... but this dwc is kinda a different ball game. Gotta learn, re-learn, and in some cases un-learn, some things. But learning, making mistakes, and applying what you have learned is definitely key

ppms going up could mean your nute mix is too strong which could mean plants are drinking more water than nutes. If you're still encountering this, just do lower dose. I can't say for sure unless I knew how much water it drank and what the ph is doing.

My blueberry OG did not like ppm to exceed 680 the whole flower stage to harvest. It just happens.

680 on the .5 scale?
 
Ok...i wanna start by thanking everybody for your help! I've made it this far... I've had too many firsts on this grow and it's been somewhat challenging...dwc is a completely different beast than growing in soil imo... and a first with leds. I believe I've gotten the hang of it so far. Now I have a new problem. I just started week 5 in flower and I'm noticing curling on the bud leaves. I've never experienced it before and I'm taking a guess that is not good. I'm posting pics with the leds on so I apologize in advance but I believe the curling is still visible. Thanks again guys!

Crickets because this is equivalent to asking a medical assistant, I don't feel good what's wrong with me?

For starters...

Water info: ppm? ph? temps?
Environment info: temps? rh%?

My first inclination would be rh or environment temps are off.

2nd would be just their response from strong fan blowing on them.

3rd is ph imbalance or nute issue.

4th they'll be fine
 
Ppm right now is 670 - 7 scale....ph is 5.9.... rez temp 70....tent temp 77...rh 64%...i just don't want it to be N toxicity and then lose mass.
