Need help with DWC grow

[Pennywise]

That's the tutorial I've used for about 3 years now.

Plant Abuse Chart

Heat Stress : Look closely below, and you'll see the brown leaf edges that are indicative of heat stress. This damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps. There's only one cure for this...get the heat away from the plants, either...

Are you in soil?

Forsure Penny, but I check ph 3 times a day and I baby the fuck out of these so ph stays correct. Res change every 7 days... my atmosphere is dialed in(sort of), I’m running an HLG 550 v2 rspec, fans, carbon filter, dehumidifier, etc... I’m a dedicated noob lol but I really appreciate your insight @Pennywise ... I will keep you updated.. and for anyone else interested I think I’m going to turn this into a journal as I’m sure to make many beginner mistakes and with the green thumb mentors on this forum we should be able to correct these mistakes for anyone else that’s having the same issues. I’ll be back with an update on the calcium feeding. Peeeaace!

 

[Allen42]

No sir, I am running DWC

Are you in soil?

I am running DWC friend... sorry for the double post, I’m just messing around with this sites features getting used to it

 

[Pennywise]

Just change the Rez and add a 3-4 ml of calmag.

 

[Allen42]

Already did sir, and I will update you on the outcome as soon as it gets some time to heal.... just wanted to say thanks again penny, I know these are noob questions but with your help I’m learning loads so cheers to that!

 

[Pennywise]

That’s why we’re all here brother

 

[Allen42]

Right on! That’s why I love these forums so much, everyone’s here to help steer the next guy in the right direction and help them step their game up. But ya I’ll be updating this regularly so just keep an eye out everyone! Peace and love!

Hey @Pennywise so this is after the calcium feeding, and it seems like the cal/mag def has stopped but now I have this purple oak type hue to the leafs.... maybe you know what this is?? Pics below

 

[Allen42]

Or is this still just calcium def?

 

[Allen42]

Same plant

 

[Allen42]

And how do you guys think this phosphorus def is going? Better or worse?

 

[Allen42]

So I added some more light cal/mag, and this issue is getting worse so I’m not sure what the problem is:/ if anyone has any ideas let me know

 

[Allen42]

So I decided to add more bloom and bud igniter, hopefully this will cure the problem.

 

[Pennywise]

Now that’s phosphorus, a dose of bloom formula should give her what she needs.

 

[Allen42]

Thanks Penny, you da man! Or woman!.... regardless, good lookin out!

 

[Allen42]

So I added a light dose of bloom as she’s still
Sensitive to the nitro in the bloom, so I went light on the bloom and a little more heavy on the phosphorus additive. Good looking out people! Much love to all who are sharing their expertise !

 

[Allen42]

So I added more phosphorus and the problem just seems to be getting worse.... could this possibly something else? ... or do I need to give it a stupid amount of P to help it catch up with its deficiencies??? Thanks a lot,

[Allen42]

I think it’s safe to say it isn’t a P deficiency.... the problem has gotten much worse ... take a look at the plant and lmk what you guys think.
