Did I burn my plants or is it a deficiency?

[louie]

Here is a condensed version of my situation. I just started using GH flora micro and flora bloom (I'm following Rez's recipe) and am brand new to synthetic nutes, I have always grown organically. Well, these AK47 clones (actually more of small vegging plants now) are about 5 weeks old and have been watering them with 3 ml flora micro and 4.5 ml of flora bloom ph'd at 6.0. I have watered them when needed, about every 4-5 days or so. I am using a peat based soiless mix with perlite and dolomite lime added. My question is, did I burn these plants or is this a deficiency and need to up my feeding. I have been feeding at the rate stated above, but the recipe calls for 6 ml flora micro, and 9 ml flora bloom every watering once clones mature into vegging plants. Last night after I took these pics I started the full vegging feeding on a few that needed it so we'll see what happens, but I figured I ask here to get a more precise answer. I wasn't sure if I needed to flush. Some of them probably could use a bigger pot now, but I am waiting another week to do so because I have no room in veg room right now. Here are some pics of a few of the different plants. Thanks for the help! pics below

They need to be transplanted and it looks like you have possibly burned them.

 

[louie]

thanks for the reply my man! So you think I burned them. Anyone else have any opinions/suggestions? The help is MUCH appreciated.

 

[ganja_hasi]

hi louie, as Phedrosbenny said, they need to be transplanted..all the rest are salt build ups..just put them in some bigger shoes

good luck

 

[louie]

So the census says that I burned them. Should I flush them before I transplant them or just transplant them into new peat/perlite/lime without a flush?

 

[el dub]

Transplant them asap.

Btw, do they have a source of magnesium/calcium?

[louie]

Hey el dub, I added dolomite lime into the mix, im not sure if this will be enough? I'm using Rez's recipe (motified lucas formula) and it doesn't call for cal/mag. I was thinking maybe cal/mag deficiency too...hmmm

 

[BPJR]

Get them into bigger pots and flush them. They should be fine. Looked burned to me too

Can't wait until I'm skilled enough to be able to see burn vs deficiency. I am using RO water but just started using calmag plus. I sure hope I can save them.

If you've used dolomite lime, it ought to be giving the plants enough magnesium, how much dolomite is in your soil mix there?

I think ganja_hasi is right on the money with a salt buildup. I dont think you directly overfed them, i think the roots are just hitting 'hot spots' in the soil where the salt has collected.

Just transplant them into bigger pots, water them a little bit but watever you do DON'T give them a big deluge of water to flush them! As soon as you transplant, if the plant receives too much water, it'll try and suck too many nutes out of the new soil it's in & you'll burn the plants even more. They need a day or 2 to recover in their new environment & then you can water as normal. Good luck!

I used 1/2 cup of powdered dolomite lime per cubic foot of mix. Thanks for all the tips guys! much much appreciated! Looks like I need to get to transplantin
