Plants in 5gal buckets... medium is a mix of hydroton and mini cubes feeds 5 times a day 15min each... Nutrients are AN Micro Grow Bloom + H&G additives....

is he using ro? is he using cal-mag or something similar?

 

[Rushoe]

I had something like this happen to me a few months back with one of my mothers that was beeing feed ro water with calmag and micro and bloom from gh...When I swapped over to feeding them with tap water they started to show sings of color spots like that also from the water not sitting out and being to cold...That would be my guess and maybe some slight toxit/salt build up....But it also looks like some leaf curl maybe hes adding to much N from the grow bottle or the calmag he might use I would cut the grow bottle out and just use the micro and bloom tweaked lucas seems to work very well....anyways just thought I would give it a shot please someone correct mean if I am mistaken.

Looks like some type of micro deficiency. The brown necrotic spots are signs of Calcium for sure, but Calcium is interrelated with Phosphorus. Are you boosting any PK right now? Shooting powder?

Also, 15minutes, 5x per day is a lot for using those rockwool croutons, if thats what you mean by mini-cubes. I only feed 4x per day in peak bloom with just hydroton. Even less if you mix in rockwool or coco.

 

[PuraVida305]

yes he uses RO and adds 150ppm of cal mag.... This is the recipe that he is using right now against my advice... ... Mopho i was thinking it had something to do with the Phosphorus also as the recipe that he is using right now gives very little phosphorus IMO... so what would be the best cure??? lucas formula or the bottle formula??? Thanks for the help farmers :yes

 

[motherlode]

shit just up the bloom a bit Id say now that I actaully looked at the "formula"

maybe even double it

Love the setup

too much water if its not a drip set up. more food. fresh res.

Looks like Mag deficiency to me. You got the bumpy taco leaves.

I just got some Advanced Nutrients to try them out and Im already showing signs of a mag deficiency. I never get mag deficiency with GH.

Try General Organics CalMag and see if that makes any difference.

Its a top drip... but i think its still 2 much water also... the rockwool mini cubes tend to hold a lot of water.... i took out a runt that never took off and the bottom half of the bucket was soaked...

EN... he gives 150ppm of cal/mag every rez... i was thinking the same thing but foliar feeding epson didn't change anything.... its his formulas that he was using...

Thanks for the help every1
