Oh man, MG soil is garbage, and no good for Marijauna, and those fert sticks are going to be makin things worse.

I'm going to suggest something minorly drastic to help ensure more problem free sucess.
Step 1:
Go anywhere and pick up general potting mix. It should have some peat moss, compost, topsoil, and pearlite in it. It's cheap man do yourself a favor and grab a big 25L bag.

Step 2.
Up root your plants, CAREFULLY with your hands fluff the root ball and gently try to remove as much of that soil as possible. Trying not to break any major tap roots. You can even trim the bottom, this will help stimulate new root growth.

Step 3.
When re planting, fill the pot 1/3 full with new soil, then lower roots into pot, carefully hold the plant in position raised so the roots dangle into the pot and touch the bottom, with your other hand, evenly fill dirt all the way around and in between the roots. Follow this up by soaking the soil right out till water drains out the bottom. You wanna be sure of your water?? Buy Distilled.it's cheap enough. My tap water kills plants. Even if i let it sit.(add soil to top if watering exposes roots.)
Step 4.
DO NOT WATER AGAIN UNTIL THE DIRT BECOMES DRY AND CRACKED. SERIOUSLY.
THEN REPEAT STEP 3.

In a weeks time when your plants over come the shock they will expload with growth. And you can rest easy knowing that your soil and plants have everything it needs and not too much of something.

The explanation for why your MG soil and nute sticks harmed your plants is a whole other long explanation.

calcium or magnesium deficiency i assume. you could go to the hydrostore and get som cal-mag, or florisious plus :bigjoint:
It's so much better off to start ballanced and keep it ballanced, rather than add this, then add that, you can end up with more problems.

MJ plants from my experience over come Severe root ball trimming and transplant shock much faster than Nutrient Lockout's and what not.

hope this helps.

Murcury Vapor falls between Cool white and metal halide.

It's for vegging. And yea hopefully that new soil helps a lot. And forget ferts for now, feed with 1 tablespooon molassas per 2L pop bottle until you get familiar with fertalizer NPK ratios and when your plant needs what. For now it should find most of what it needs in that new soil.

some vitamin b1 or super b + should green them back up if they are yellow you can add it in their food or you can dillute it and spray it directly on the plants the yellow is probably due to overwatering just let them dry out a little also u shud plant them in a a potting mix like hp pro or sunshine this is a soiless medium that will allow you to add whatever nutrients you want. You should definitely have a ph/ppm/temp meter ph should never be over 7 and water temp shud be around 25 degrees celsius

you should never expose a plants roots let alone trim or touch them. I cant even think of a reason you wud have to expose them any uv rays can damage your plants roots severely only slowing you down

Don't be a muppet. You got UV rays flooding into your house? Come on now, although that's true, the window of time here is mere minutes. And if you never heard of root trimming, do some more research before you go knockin ppl down, espically when their reputation far outweighs yours on the forum.

Also, soil less mediums are not a good idea for beginner growers IMO.

That doesn't necessarily determin sex. Tall generally Sativa Strain
Short bushy usually Indica strain

I'll go back and look at pics.

You can't make it Hps. You can use it for veg, but It'll be slower than a Metal Halide, or even 6500K CFL's.

Hps bulbs require a matching ballast specificallyrated for the bulbs wattage.

would i be able to just take the built in ballast out of my fixture and replace it with a hps ballast
Err that seems like the hard way to do it, but you could do that.

I would rather, run a long cable from the HPS ballast to a socket, maybe you can harvest that from your MV unit. This will allow you to have the ballast part outside the grow cab. And make for easier positioning of the bulb.
