Hello again people. I hope you're healthy and well. My Sour Diesel Auto from Dinafem is showing some weird discolorization that I've never seen before. She's 16 days old from sprout and growing in Plagron Bat-Mix soil. I've been feeding her 1mL of BioBizz Bio-grow, 1.5mL CalMag per lt of water. Also was feeding her Plant!T First Feed 5-8mL per lt. of water the first two weeks. Any ideas what this is? It's not Iron deficiency because it starts from the tips. Also, I've read on the Plagron website that there's no need to use any nutes the first 6 weeks because the soil has plenty. Still, doesn't look like an overfed plant. Temp and humidity is also not ideal. Air circulation is great (2 fans). Any ideas what is going on?

Thanks for the reply. Yeah I have and I will use it. Yeah I always feed with a nutrient solution of 6.2 - 6.5 ph.

Okay maybe work on the humidity that makes a big difference when they get about that size

Those bottom fans look like copper or magnesium deficiency

I'm using a 240w KingBrite. It's at 100% since day 1 of week 3 and at 24inches distance. I will stop the nutes for a week to see what happens.

IMO it's too late to stop feeding.plus just noticed its an auto. Maybe the next two just ph water to prevent lockout ...then feed/water/feed to your plants liking. Keep an eye to see if that moves up the plant or stays the same. I'm sure some others will have some opinions as well.

You should not add any nutrients for at least 6 weeks. Plagron batmix is pretty strong mix.

Probably lockout from overfeeding. Looks like mag def like @Porky101 suggested.

Don't flush with Epson. You will lock out CA and N possibly.
