Crispy Leaves with spot...

[Scorp1on]

High all I got some young plants in veg that are showing some problem, 3 diff strain are showing it, I got maybe 3-5plants looking like that...

Ice - / - Speed Queen - / - Hashberry


Some info...
My runoff PH is 6,5-6,7, I used nute only 1 time(last week) 5ml of PBP grow/Cal-Mag/Liquid Karma for 1gal. I use a bit of CAL-MAG & LK with all watering.
Light is 400w MH 18/6, Temp is around 70 when light on with 40-50% humidity, my soil mix is 20lpromix soil/5l perlite.
Im growing 10diff strain/5seeds of each, only 3 strain are showing that problem

I thought maybe its a CAL-Mag problem? or light burn? but my light was at least 6inch away, I moved it to 10-12inch...it start with some spot and then the leaf become all cripsy and almost yellow....

Any help would be greatly appreciated, I don't really care about the sick plants cos I got alot, but I wanna know what I did wrong? sorry my english suck, Im doing my best!

Edit: They are 3 week old since sprouting, so lets say they got 14days+ of veg...after looking more closely at MynameStitch's sticky it look like too much baron or not enough...on the PBP/CAL-MAG/LK label they dont list baron

I am having the same problem with one of my plants and cant figure out what it is...
I thought it was boron at first but I was then told that plants at such a young age are very unlikely to have that kind of micronutrient deficiency...

looks to me to much of something test the ph in your soil if you have one

well my tap water is 6,8-7 and my nute/water mix is 6,4-6,7...runoff is almost the same...never off range

I think you need to transplant your kids into larger containers. It may be that your plants are showing signs of various deficiencies because they have depleted the soil in those small cups. I've had plants become rootbound after only 2 weeks from seed in those containers.
After transplant, start giving them a light feeding every 3rd watering.

Good luck m8......

I agree with Bipedal.
Let those roots stretch.
Also, pbp was a Mf'er for me and nute lock.
I would start watering with pbp only and then a calmag/liquid karma the next watering.
Did you ph the nutes before feeding?
Also, are you using tap water?
With the pbp, karma, and tap water, I wouldn't think calmag would be needed.
Stay peacefull

P.S.
Leach them till you get a 6.8-6.9 runoff.

Do you have any idea what the ppm/EC of your tap water is?
Are you using a public water supply or a well?

Definitely looks like it's time to transplant though...possibly a nute lockout as well, but that could just be the rootbound.

whats up man... time to transplant for sure, not sure i wouldve been as that quick to catch that as the other guys. One thing though, is your 400w aircooled?... Because 6 inches is wayyyy to close if its not. In my experience, dry leaves has come from too much heat and low humidity. You said temp was 70 degrees, but i bet thats ambient and not whats under the light. Try misting your plants with tap water. Maybe the occasional foliar feed with light nutes. Less is sometimes more. Good luck and keep it easy ~caddy

Thanks to everyone for their reply,

1- I dont think its due to the need of a transplant because the plant started to show this problem at around 10days old..they will be transplanted this week-end.

2- I always PH my nute, I'm using tap water with a ppm around 50. I never checked my ppm for those new plants but its under 400ppm when I nute...

3- my light is aircooled, and very cold I can almost touch the bulb! The veg room is alot cooler than the flowering room and my temp meter is in the flower room and reading around 70, I can get the temp easily under 65 if i want too
