Leaf discolorization. Why? :(

[Eugenios]

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?

it looks like nutrient deficiency have you been checking your ph? and also your humidity is at 29%!! way to low do you have a humidifer?

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

Lights? Distance?

Those bottom fans look like copper or magnesium deficiency

 

[AntToeKnee]

oh right have you been using cal-mag?

 

[SBBCal]

A plant that size/age and that soil shouldn't have needed any nuets at all

 

[AntToeKnee]

Personally i like my plants getting nutrients and growing asap but he is right they dont necessarily need it unless u have problems like this you should have fed it about 1 or 2 times by now especially cal-mag

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.

I've been feeding Calmag from the start of the 2nd week.

maybe move the light to 30 in. too

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.

 

[AntToeKnee]

yeah that right there sounds like the best plan

Mag def.

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.

Mag def.

Thanks for the reply. I will flush with epsom salts.

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