yellow leaves???

OveRRide · Feb 27, 2011

Huge problem... i have a 600 watt hid in a 4x4x6.5 grow tent it's about 24 inches above my three clones... so far nothing but reverse osmosis water with no nutes... the new growths are quite yellow... also the leaves are a bit droopy. The temp in there is a good 80... the light is air cooled exhuasting outside.What's the problem? something to do with nutrients? ima newbie grower.View attachment 1464855 :-(

Looks like they need watered more often, if you ask me. Give 'em a good heavy soaking(PH'ed correctly), and see how they like that. I'm betting they perk right up.

The Reverse Osmosis water will be ph'ed correctly right? i watered em today but dont soak all the soil for fear of overwatering. Are you sure that's what i should do?

Check this post out:

It also look like your plants are not close enough to the light. I would put them on a table or whatever or lower your light so they are roughly only 20 inches from your light. If your light is not putting off much heat you can actually put them closer about 13 inches.

I've seen that chart but fail to match up the symptoms exactly. Also, that last image of the tent is mis-leading. The light is much closer to the plants that that. That was a few days ago.

Hmm....Seems like we have another victim of the "OMG, don't water your plants or they'll die" bullshit, that goes on around here, waaaaay too much. Grrr.....that pisses me off.lol When you water, water heavily, so that every single crumb of soil gets wet, THEN, let it dry out for a few days, until about 75-85% of the moisture has dried, or been used by the plant, then water heavily again. Overwatering, is caused by soil with crappy drainage(most commonly), that stays wet too long, or by someone who waters all the time, never giving their soil a chance to dry out. If it dries out once a week, you'll never have a problem, no matter how heavily you water, when you water. Think about the rain outdoors.....If MJ plants couldn't handle heavy soakings, they would've went extinct years ago. Agreed? Also, ever notice how everything goes through a growth spurt, after a nice heavy rain? :wink:

I'm not sure about RO water, and it's PH, I never used it before. Sorry, I wish I could help.

^Relax, they're unhealthy, showing deficiencies, and aren't going to perk up right away, like I made it sound. They've been starving for awhile, so give them a day or three, and the new growth should like nice and healthy.

OveRRide · Feb 27, 2011

Ok, like i said... they are more droopy now which makes me fear OVER-watering... check them out.Also... Thanks for your help and advice i really appreciate it.

Jawbrodt is giving you good advice, listen to him

smokebros · Feb 27, 2011

good luck bro, gotta get that watering cycle down. I always go by weight.

kepitgrn · Feb 27, 2011

they look over watered..water them once every 7-10 days when the first couple of inches of soil is dry...as long as the soil and pots are draining good they should be fine

OveRRide · Feb 27, 2011

lol how did they look in the first pics? Jawbrodt said they looked underwatered... which is the only reason i watered them... IM SO CONFUSED.
