These plants are 17 days old. As you can see, the top left plant has been burned, and I'm trying to find out if its nutrient burn, or some type of nutrient deficiency. My guess is thats it's nutrient burn. I've been using a bottle of Fox Farm concentrated nutrients. I mix 4 teaspoons of it with a gallon of distilled water, and water with the nutrients every other day, but I may have overdid it a couple times. All of the plants have been burned, but the top left one (critical kush) has been burned the worst it seems. Earlier today I decided I would flush all 4 pots with a decent amount of water, I'm PRAYING that fixes the nutrient burn, but then again I'm a beginner and don't know that much about growing marijuana and it could very well be a nutrient deficiency. That seems unlikely to me since I've been feeding them every other day, but I'm no expert. what should I do? Thanks.
Your probably right with the nute burn diagnosis. I usually lay off feeding nutrients (especially Fox Farm non organic stuff) until the plants are really growing and taking off. I'd say you prob introduced it a tad too early. The plant is already adjusting to the nutrients in the soil after shedding the baby leaves (if that's happened yet) and then BOOM you hit it with another dose. Just feed water for the next week or so and then it should bounce back. Those leaves will remain damaged but watch how the new growth is responding to strictly water feedings. Nothing to go crazy over but watch the nute feedings this early. Also, Fox Farm is nice soil wise but I wouldn't recommend their nutes at all. Fancy labels but not as good as some of the cheaper nutes that do more and are organic. I would check out nutes from Blue Planet or General Hydroponics. Just my opinion though so no offense meant.

Feeding like that is way too much. I never feed but every 2-3 weeks at first. The dudes who sell plant food tell you to use 10 times more then you need. When they are big monsters you can feed the shit out of them. Till then go easy. Nice indicas, be good to them. Dont love them to death.
The flush should help but your actually not in that much trouble. Plants still look healthy. How often are you feeding? And are you doing any foliar feeding? I doubt it's a nute lockout at 17 days old unless you've lost your mind lol. Sent from my iPhone using Grasscity Forum
I water daily. The soil I'm using has excellent draining properties and I also have holes on the bottom of my pots to allow for drainage. When the soil feels dry, that's when I water. I'm not familiar with foliar feeding. What exactly is it? Sent from my iPhone using Grasscity Forum
@[member="dopeisxavi"] You're definitely right about the fox farm nutrients. It's way overpriced and I definitely could have bought way better nutrients with my money. Unfortunately, I'm a newb and didn't know any better, haha. However; the fox farm soil I'm using is pretty decent. Sent from my iPhone using Grasscity Forum
What should I be looking to fix. This is my first grow. I'm not using any nutes yet, using 11 23watt cfl on an 18/6 cycle. honestly my Ph level is unknown tomorrow I'm going to purchase a Meter and Ph up and down. I water when I feel soil dry to the touch. But what does the browning on leaves mean? Should I start nutes?http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514328http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514329http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514330http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514331http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514332http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514333http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514336http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514337http://forum.grasscity.com/index.php?app=core&module=attach§ion=attach&attach_id=1514339
Looks like a couple things going on. Nute burn possibly from the soil, possibly over watering as well. Do not water until the pots feel noticibly lighter, like 10 times lighter than when you just freshly water.
Ok this is definitely one of the issues. Regardless of how good the soil and holes drain the water, you still shouldn't be watering daily. This never gives the soil a real chance to dry and opens the door for tons of bacterial infections around your roots. Dry soil is actually good for your root system because it forces the roots to reach (grow) and search for nutrients. Watering everyday is going to drown your roots and stunt growth along with a lot of other things. This is why your leaves are hanging and look heavy/soggy. I wouldn't feed anything into the soil for about 5 days. Let the top of the soil become dry and when the dirt dries on the side and separates from the pot....then water. Or even better, just wait for the leaves to perk back up. Whatever you do...don't keep watering everyday. Foliar feeding is when you feed water or nutes to the plant by spraying the BOTTOM of the leaves. This helps to simulate rain, keeps your plant clean, and more importantly allows time for the soil to dry and roots to stretch. I grow in 5 gallon pots and only water once every 5/6 days. Between those days...I'll foliar feed. This doesn't mean soak the plant either....get a cheap spray bottle and just mist her from underneath. It's also important that you only do this an hour or so before the lights come on or before lights go off (preferred). Foliar spraying with the lights on will burn your leaves.

Need a little more info....how often are you watering? First issue is not ph'ing your water. THIS IS A MUST!!!! Certain nutrients can only be absorbed by plants at certain ph levels. The picture below is a chart I keep in my tent. It shows the ideal range for ph'd water and what nutrients is absorbed at what level. Purchase a PH tester kit...they are usually non expensive and come with PH Up, PH Down, Test Solution, the chart, and a dropper. You don't need an expensive electric one or anything like that and those sometimes give you wrong readings. If your not using nutes then the spots are probably from the lights. Looks like your doing a little bit of overkill at this point. 11 lights is a lot for infant plants. The plant is communicating this by curling the tips of its leaves. The plants look beat down in a few of your pics because they are getting smashed by heat/light. Combine heat stress and non ph'd water and this is how we got to this point. Also, do you have a humidity/temp gauge? I'd imagine the heat is a little high with 11 lights. Lastly, I don't agree with the "water when the top soil is dry" theory. This isn't always an accurate measure of how moist soil might be under the surface. When you feel like you need to water....wait another day. Dry soil helps force your plants to search (grow) for nutes. This helps build better root systems and a bigger/healthier plant. When you go to the hydro store I'd recommend getting a ph tester kit. There are good digital ones but I've seen nice grows ruined by faulty ph readings so I shy away from digital. Also, when you get nutes, look for something that is PH balanced. This means once you PH your water, it won't be affected by the nutrients you add to it. I personally prefer General Hydroponics or Blue Planet nutrients. Boring labels but cheaper, more effective, and ORGANIC! Don't be fooled by the cool picture on the bottle lol. Here's a pic of how my plants look doing everything I recommended. Not monsters yet, but i always get complimented on how green and healthy my plants are. Hardest thing for a new grower to do is LEAVE THE PLANT ALONE lol. Sent from my iPhone using Grasscity Forum
Here they are today. Not much of a change but I don't see any new brown spots. I'm really hoping that the flush did the trick. Sent from my iPhone using Grasscity Forum
Please help, I'm in the early stages of a type of deficiency but I'm not sure which one or how to counteract it. I'm using a DWC hydro setup and my girls are starting to show signs at the end of week 4. Flaky brown spots are starting to form on some tips of foliage and some in the centers. Water never breaches 73 degrees and my pH is consistently6.0-6.4. Just 24 hours ago one plant began developing a faded yellow on the very top of the plant and it's very noticeable. Just today I trimmed the dead foliage off. Was that a mistake? What should I do to prevent this in the future? I'm growing in a closet with no vent and I had a friend explain that it may be CO2 deficiency and to take yeast and mix with water in a cup to make a more plant friendly environment. I have posted pictures below and forgive my ignorance because this is my first grow but any constructive criticism about my setup and what I can do for my babies is much appreciated.

With hydro a consistent ph can cause issues, let it drift from 5.5 up to 6.5, my brother lets his tables drift to 6.8 before res flush refill and correction.
Is it normal for the bottom burnt leaves to keep yellowing? All new growth is vibrant green, but the very bottom leaves are slowly continuing to yellow. Should I flush again? Here is a picture taken today. If you compare to the last picture, you can see the yellow leaves getting more yellow, as well as the the new growth on top remaining green.

If they are the very bottom set of leaves then it's pretty standard. Either clip the tips or pinch it off completely if it bothers you. You'll want to pinch those leaves off eventually anyways. Don't flush again!!! Lol the new growth tells the story of your current methods. The seedling is on it's way and looking good. Don't take two steps back. If it were my plant id pinch the yellow ones off and let her be. "It ain't going to grow itself"
@[member="dopeisxavi"] Thanks a lot man, you've been very helpful. I know I'm a total worry wort when it comes to these plants, hopefully that will pass with more experience, lol. Sent from my iPhone using Grasscity Forum
You guys know what could cause this: These are clones that have been in happy frog soil for a week under a A/C 400w MH I'm thinking heat caused the curling and twisted but what's the discoloration from. Any input is greatly appreciated Sent from my iPhone using Grasscity Forum
Explain what you did during your cloning process and what you used. How long you waited for root growth and so on please "It ain't going to grow itself"
