Help! Not sure what is wrong!

[Canninoob]

My seedlings have been growning for about 2 weeks now and out of nowhere they started showing brown spots on the leaves and tips, i dont see any signs of pests and i just started using the bottles recommended dose of nutrients so i dont think its nute deficiency, could it be nute burn? I'm using liquid karma, cal mag, and PBP grow all mixed with distilled water and PH measures to about 5.5-6.5. I need suggestions on what to do. I included pictures. Please Help.

Possible nutrient burn and/or cal/mag deficiency?

 

[Canninoob]

Idk, I was using cal/mag so I hope burn

Did you flush? Have you reduced the amount of nutes? Also, have you checked out the plant abuse chart? If not click the link in my sig and check it out. You might be able to problem solve until someone can diagnose your plant.

I've been giving them straight ph'd water from the tap for about 2 days, just crossing my fingers and waiting

There are many people on here that know much more than I, but I would side with burn. I think it is a bit early for nutrients- I would wait until you plant them. I hope it clears up and I will check back in to see what happened. Good luck!

Yeah I'm pretty sure it was burn, I used just normal ph'd water for 2 days and at end of second day that plant fell over and I feared the worst, so I made a mix of 1/2 strength mutes that I was giving them when they got the spots, and no kidding within an hour and 30 minutes it went from laying on the ground to standing straight up firm, like Viagra for plants.

1. What's the medium you are using? 2. What's your ppm?

 

[Canninoob]

I am using rapid rooters as the medium, and idk the ppm, I need to know where I can get a measurer, I have a ph test kit

It looks to be an obvious over fert. U confirmed it when u said u said u followed the bottle's recomended dosage. What nutrient line/brand are u using? Dosage for what aged plants? U also said ur PH range is 5.5 - 6.5. How are your measuring ur PH? Are u going hydro, soil, soiless? Cal-mag with distilled water, yes. With tap water, maybe, maybe not. Cal mag is really to supplement reverse osmosis (RO) water. Ur in rapid rooter plugs, correct?

 

[Canninoob]

Yes rapid rooted plugs, I was using recommended for vegetative, botanicare Pure blend pro grow, liquid karma, and botanicare cal/mag. Plus a little H2O2. It's soil-less, and I'm using the liquid PH measurer from GH.

Between waterings, feed 1/4 strength (of the bottle's instructions) for the rest of the week. Next week go to half strength between waterings. The following back the recomended schedule. Soiless like cocoa, hempy, what? When do u plan to transplant the plugs and to what sized pots?

I plan to transplant the plugs into 3 in net pots set up in a large DWC tote with hydroton as medium

Ok, let's make sure u have healthy new growth and the problem doesn't continue to spread up the plant as it grows before transplant. I suggest u stabalize ur PH around 5.7 - 5.8. This means it should be in that range each time u water/feed. Not sure if u know so I wanna cover all bases. Be sure that ur adjusting the PH AFTER u mix ur nutes and water. I would also like to see a couple pics of ur roots in the plugs. Roots need a healthy start before begining DWC esp if ur new to it.

 

[Canninoob]

I measure oh before each feeding, and I'm going to try and get some root pics in a little bit
