I did not read this whole thread. Do you have positive pressure on your intake? Helped me drop 5 deg with a booster. Im also running 600 in a small space regular hood. I have no issue with MH yet. You need a quality exhaust and inlet fan with the right ratio. Also cold air humidifiers work...

I haven't thrown in the hps yet. I may be in for a surprise. Ill take your advice and do a dry run to see if I need to get an aircooled hood before flowering. Hmm. Thanks! And Jef let us know what you ened up going with. If you do go LED let us know as im interested but don't have the balls to...

Sure 15, hps do run hotter. I prefer better yields, and just keeping an eye on things youll be Not burning them? Im also running a non aircooled umbrella, with 32 (0 deg celcius) degree ambient temp on entry with a booster fan + your reg exhaust. So maybe I will run into these heat issues in the...

600 watt digital dimmable HPS/MH system. Use MH for veg, HPS for flower. I run a 3x3 tent at 75% power. MH bulb. Be prepared for heat. Stay away from LED if your new. This is the STANDARD. Not to mention the color an mh system brings to your foliage. This system is useless unless you can vent...

This seems to of stopped spreading after feeding it 1/2 strength nutes.

Its doing it again. Im going to transplant into some softer soil, get rid of the peat pots if the roots aren't entangled and try to start from half scratch. Thanks for the input! And that's very interesting about the chlorine in the water. Ill use distilled water for a week and see. Also ill...

white powder mould...no?

From my basic knowledge it looks like the edge of nute burn, nitrogen toxicity to be exact. But im no expert. Looks like a similar issue I had. But its doing the claw and showing signs of a hot soil

Great looking seedling. No issues their. This is nute burn in a seedling. By yours truly

I used phed tap water. No nutrients and no cal mag. Now their doing good. I ended up with a lollipop and now its really taken to half strength nutes and mag and cal. Ill post a pic tonight. Ill let her breath. These things are very picky with nutrients huh.

Rapid rooter by general hydroponics. Great stuff. You can throw it straight into a hydro setup or any growing medium you so wish. Amazing for cloning I hear.

Wait that is facing down curled up isn't it looking at the photo. SMH.

I have no patience and proceeded to look down my rapid rooter after two days of germ. This is my first time with a rapid rooter. I usually germ in water or paper towel then into the medium but I am new with this. Reason is, usually you can get the tap root facing down when you germ first, but...

I fed it half strength. And this is what I got. Another case of nute burn. My soil is too hot im pretty sure. Its a potting mix.

Update - Shes getting worse. Its Def nute burn but its losing surface area on the leaves. Its like an acid burn?? The way it looks. Is this thing done for? What the heck I going on??!!

150w hps @ 7 inches. I turn them off for the photos as requested. Ill use cfl's to light up dark spots on later veg and flower however a 2x2 mylar room is filled well.

Update - New growth seems healthy! Thanks! So I can call her mature and re introduce nutes when she grows a few mature (5 prong) leaves? Side note - Am I pushing it with a 23wcfl @6500deg 4 inches from the seedling? Temp is good. No cotyledon? Do I need light at this stage? I read mixed...

I had the same thing. Nute burn. Flushed with PH water and fed a seedling dose of root 66 and suger daddy. All is well. Hope she gets better . And to flush the plants "will not hurt them" so I would flush them all if their exhibiting the same characteristics. Id say within a 24 hr period you...

Thanks Bustin. Its a potting mix. So essentially it is pre treated. Ill go with fresh water and seedling mix. Its technaflora. Less worried now. Side note Is it time to re pot? 5 gallon seems the norm?

Hey all, 10 day old purple kush plant. The plant was over-watered, then some slight light burn, all is well, until she went yellow on the tips, brittle and is turning black. I backed off the 150w hps in the 2x2 space and flushed her with ph water. The new growths look ok but the old leaves are...
