hi there, dolomitic lime is dolemite lime. It is a ph stabilizer, which is comprised mainly of calcium and magnesium (it is used to make acidic soil's ph rise). Actually it is calcium magnesium carbonate or camg(co3)2 (sorry about subscripts). Unlike hydrated lime, which is Ca(OH)2, it...

here is a good guide that was posted in my cry for help. http://www.greenmanspage.com/guides/plant_abuse.html I would also take a look at zinc deficiency, but not knowing more I can't be certain.

did it start from plant bottom/up or top/down?

also, please no more ffos vs. sunshine mix debate here. I've chosen sunshine for it's ph stability and to know exactly what nutrients i'm feeding my plants at any given time. One is soil and one is soilless. These are two different things. Thank you mm

Hi all, just an update. The ph of soil mixture spiked. Must be high b/c I watered with h&g drip clean .5ml, 1/4tsp h&g roots excelerator and 1/2tsp dyna gro protekt (all per gallon water). Water was PHed at 6.0 (added ph down), because I thought it might be slightly alkaline. The runoff was...

They look great, really beautiful. I would give them some more nitrogen so you don't get any leaves dropping if you have 3 weeks to go.

how long did you veg them. couldn't tell if it was seven or eight weeks. How tall were they at end of veg? Also, how tall are they now. Thanks for taking a look at my post by the way. mm

Hi, I'm still fuzzy on how the grower/patient relationship works. I'm growing for a close friend now and want to make sure we are doing everything legally. How do other growers handle donations for electricity, supplies and time? thanks mm

Does anyone use this product? http://www.emearth.com/emshop/index.php?main_page=product_info&cPath=1&products_id=329 I use EM-1 to inoculate my garden space, compost pit and to create bokashi. It's cheap and you can create you own effective microorganism colonies. I think it contains over...

Here is pictorial update on the mag deficiency.

Hi Shrubs, Thanks for your quick response. I thought the lockout could have been from a calcium excess. I haven't fed cal. mag. to fix the problem. i don't think the flush I did with epson salt could hurt. Putting more magnesium in the soil mixture might not help either. With lockout...

riddle, for your soilless grows what do you ph your water at? what effect does grow medium have on run off water of sunshine #4 mix? thanks.

Thanks for the info. They look good.

Thanks chebus for posting the plant abuse guide. It's great. After looking at the guide posted by chebus, I think this is most probable. The question then becomes why did the deficiency occur? And, what can be done to resolve the issue? "Mg can get locked-up by too much Ca, Cl or ammonium...

hi ub, I've read quite a few of your stickies and that copper hydroxide experiment you ran on drugs forum. Good stuff, you know your botany. Got a couple quick questions i would like you to answer. I have some vanilla kush plants that are showing slight leaf burn because I believe they...

hi, First off, i'm subscribed b/c I think you have the furthest along vk journal on the site. props. i have vanilla kush going right now and have a question for you. Were your vk's stems purple about 2 1/2-3 weeks from germination. Right now i have what i think is nute burn, but some think...

hi, i have a vanilla kush going right now and have a question for you. Saw your pic in another journal and it looked like vk's stems are purple. right now i have what i think is nute burn, but some think it is a mag deficiency because of the stem. Could you check out my post and tell me if...

never mind. i feel stupid. i think it is nute burn.
