Help save my plants lol

Looking for some advice on what’s happening to my girls. Ppm is good PH is good I’m guessing calmag deficiency so I added if on Friday and it kinda looks like the new growth is coming in green. Any ideas ?

My first guess is potassium def, but tell us more about your grow medium and pH/ppms.

I’m growing one in promix HP and other in hydro, using PH perfect at around 850PPM and PH of 6.0, my last grow was great and the only difference in this one is I’m using RO water, I’m temped to go back to tap water. It’s coming in at 170ppm

I’m no hydro guy, but I think pH 6.0 might be a bit high.

5.5-5.8 is recommended for hydro.

Hmm, looks like nutrient burn imo.

Yeah I been fighting this for 3 weeks, I kept upping my ppm to fight the light green so it’s possible some of the leafs are fighting nute burn but I don’t think it’s the cause of the light colour plants

I see. I’ve never really been a fan of the ph perfect stuff. Seems to be great for some, and horribly for others. Hopefully the calmag will do the trick.

Would it be bad idea to try and switch Back to my GH nutes now ?

Not sure. Generally it doesn’t really matter, but I don’t know if ph buffers in ph perfect will get out of whack. I would think you could run a flush and switch if you wanted to.

Looks like nute burn to me. Light green can be strain-specific and not really a good indicator of issues. Most important to know the TDS of nutrient solution, how often it’s changed, etc.

You can return to the GH nutes with no issues at your next rez change…
