Mg Deficiency?

Just noticed this like 2 days ago.

Got them on a flood table under a 6bulb 4ft T5.

Running...

Tap Water
Botanice lineup

25gal res

120mL PBP Grow
25 mL Silica Blast
25 mL Vitamino
25 mL Hydroguard
25 mL Liquid Karma

The ppm always started at 7 then i adjust down to 6-6.1pH and the EC was 1.1 this time. I don't use cal/mag since I run tap water, but threw 20mL in yesterday to try it.

Any ideas?

Probably calcium if the top is more affected then the bottom. Calcium in tap is in a large molecule form that isn't as easy for the plant to take in as other forms. Maybe take your ph down a bit every now and then too.

Some purple stems too

Looks like she needs more cal\mag, feeding.

How is botanicare is doing for you?

Heard just bad stuff recently about thier line.

Got the silica blast bcz there was an offer on it, didnt use it yet, but I doubt the proudct already!
