Thank you oilmaker, this thread seems like the HUB for MARS growers and the more people posting and troubleshooting the better for everyone. :D

thats what id hoped for when it started, there was NO info on these units and the people who'd paid $600 for LEDs were very negative towards them. maybe to justify the price tag they had paid. i also grow with a $1000 Budmaster 2 But ive found these units to be well worth the $300 and i have grown my best plants with the MHLed so that says it all.
 
End of week 2 flower...im right on the limits concerning heat and without this led light I would be in trouble (still worried as we havnt hit full summer yet)...I used 1/2 grow and 1/2 flower nutes for the last week which seemd to work well and gave them there 1st feed of flower only nutes today

week 2 flower pic... happy so far:cool:

Hey all,

I am going absolutely insane here. I have never had this problem before but wow I am feeling it now. I have the MHLed 3 foot above these girls on Veg switch. I have been spraying them with the epsom salt mix that most of us know, I have a fan running and I am going to change their nute bucket probably tonight and see if I can refigure it without silica this time and half the nutes that I did last time. I'm ata loss, I feel as if I have tried everything with this light and plants and I've never had this much trouble. Any advice would be well taken.

BTW, Realstyles you have a crazy setup, good karma your way man.

Well Wazzax, I am definitely doign a whole water change on the babies tomorrow. Hopefully this crap clears up. I'm not so sure about the K def, but it is something that I have looked into as well. Hopefully something gets put right soon, I'm going to have a coronary.

Hi All, Just found this thread about 3 hours ago (30 pages of good reading i recon). Ive been looking at a few different lights lately and was sold on the 315 LEC but the price isn't down to my range yet. But these are a good price for the results.Sounds like you aren't having heating issues so far with the 600W in a 4x4 tent. A previous poster said that around 50 true watts per m2 should be used, that would probably be a 1500W in a 4x4 to get 800 true watts maybe. This would have to start pumping out a bit of heat i recon.

What are your temps getting to on some of the hot days?
What percentage of the lights would you say the switches on the 600W take out? just for solar system calculating
Has any1 heard of LED's hitting the gram a watt mark?
Reflector or no reflector?

Great tread and keep up the awsome grow reports

Cheers

Hey mate and welcome...

so far up to 36 degrees celcius thru the night (ambient is 28-32 during the night atm though where I am :shock:)
looks like about 2/3 of leds are on with veg switch...3/3 with bloom switch obviously
a gram per watt would probably be doable with the correct strain and given enough time

It looks to me like you may have a problem causing other problems so whilst you're diagnosing a mg def it's actually mg def being caused by something else. A lockout of sorts. You definitely have signs of mg deficiency but I doubt that's what is causing it. I presume you use e.c to calculate nute and check your ph often so if suggest a water change and a fresh batch of nutes. If you haven't seen an improvement using Epsom salts then it's defo a lockout. Salts work fast. It's not K def. 100% sure on that. It looks like you have nute burn. Do you have crispy ends on the leaves ? K def doesn't make them crispy. It makes them limp and lifeless. I think you have a sodium build up which is causing all sorts of issues. Let us know how you get on. PH 5.5-6.2.

Is your res too warm ? Might be the strain too.
 
End of week 3 flower ...went with all flower nutes this week and things seem to be going well ...they are drinking lots of water but that is probably down to the heat... comparing this weeks pic to last shows they have kicked along really well and they are getting some nice frosty bits starting to show now aswell 8-)

Hi,

Mars Hydro first grow here. I am using the 150 W unit inside a 45 gallon Sterilite bin. I planted two seeds in soil (Miracle Grow all purpose potting mix...I'm on a budget) One G13 White Widow and one original berry. So far the only seed to germinate has been the widow. The original berry was inspected after 7 days. The seed case had split but there was no appreciable tap root growth. I placed the runt seedling in moist paper towels and wrapped in cellophane. I am hoping this will encourage the tap root to grow. So far I am very pleased with the MH 150 Watt. The unit runs very cool and I have a ported exhaust fan in the top of my box.

Here is my rig. Thanks for starting this informative thread.

Has anyone had any success with using used coffee grounds for Nitro? I've been composting these with ground egg shells and potash for later use.

Ya know I really could never figure it out, but my guess now (promise it is my last hypothesis) is that I got root rot and it locked out the nutes in a very critical time in growing. Having the LED on full blast while the big plant was in there made it too warm ambiently and made the res buckets too warm is my thought. This would explain the trouble I had diagnosing the problem and why they stayed so small because they didn't have anything necessary to keep them growing. Damn! I will start more soon

If you had a good microbe population it wouldn't have mattered..

I'm getting ready to flip mine to 12/12 in a couple days :) i now have two 150w mars hydro reflectors in there :) one plant it stretching a lot it must be a good 3/4 of a foot taller than the others but the rest of the canopy is fairly even which isn't too bad considering I'm growing a verity of hazes and some a week or so older than the others how are your ladies doing @WazzaX ?
