WTF is this....

It looks like either some sort of salt build up or nute burn/lock. I went ahead and just gave fresh water, but im worries its forever hurt. I've never seen this happen it literally happened within 2 days. I've used alil bit of grow big, and a tiny bit of flowering nutes on and off but only a very little bit. here is it before and now.

Before.
AFTER:

It would help if I can see the plant outta the red colored light but i agree with above..can be over feeding

Its really hard to tell under that hps...They look overfed....

Some one fed your plants and then someone either forgot and then fed again or someonelse fed them and then they probably got overfed and finally committed suicide.

r ur leaves very dry & crispy? Honestly, in pic #4 it looks like a severe deficiency of mag & cal. hows ur ph? & have u checked ph runoff? this just doesnt look like chemical burn to me.

I only give it the tiniest bit, like a poland spring water bottle cap full. thats not even close to the recommended dose. And i dilute it with a lot of water and feed every 3-4 days. could it be from the soil still have its own nutrients in it? And is it possible for the plant to survive still if I flush, and feed water for a week?

Yes the leaves are very dry and crispy. I thought it was a deficiency but theres no yellowing anywhere. I looked up all the deficiency symptom's and pictures etc. it just doesn't match.

well then, that does indicate burn. is ur soil premixed with nutes? all u can do is flush good, make sure ur ph is where it should be & give it time to see. have u used any cal/mag type products?

dont get discouraged & ignore the last post, it was not very helpful. it is hard to tell u exactly without more info & better pics, but just to be on the safe side, discontinue nutes & watch ph closely after flush. come back in maybe 5-7 days & post more pics if u want. best of luck, hope they survive

Ya people like the fucktard, need to be seen not heard its not helpful info. Just remember his name and give him same advice when he post real questions. Most people on here are good people and helped me out alot. RIU is a good place to get alot of info. I hope you will post pictures. Sorry for the fucktards on here.

Hahah Yea definetly I know there are people like that and considering the fact he has very little rep, I am only going to discredit is information. On the other hand the only other info I can give is that my soil does have prenutes, and that is why I'm getting these burns. I need to be more patient. Gona do a couple flushes, and if I don't notice any change I'll either try and ride it out or start another one. This plant is an autoflower, its been 29 days since sprout, Thank's for the info everyone.

Could someone explain real quick about micronutrients?

Really diffident mean to offend anyone, just playin..... I was not calling doboy anything, just saying it's a pain in the ass when this happens.... sorry doboy, and fuck that pussy that can't take a joke.

Lol right, hey another question the leaves are startring to feel alittle better since i flushed with water, however they look terrible, do you think i should cut the off the leaves that look terrible which is almost everything, or do u think I should just let it ride for the time being, I feel as though it can still make it aslong as i flush it a couple times but if its unsalvagable through flushing or cutting the leaves that are really bad then I'm gona scrap it. Unfortunate since its flowering.

NPK are macro nutrients. All the rest the plant needs in small amounts, like magnesium and boron and iron et al.

Grow big is dangerous for a first time grower. Go with something tried and true and save the experiments and special magic juices for fun later. Flush the plant like mad then go back to a light recommended strength of nutrients from a known company. After new growth gets going you can cut all the ugly shit off.

I wouldnt worry about it 2lazy. Your previous post hit the nail on the head. Some folks just find it difficult to accept the truth...and OP, you have ph issues also........

Why/how is Grow Big any more 'dangerous' than other nutrients? Its about as 'tried and true' as it gets. FoxFarms is a 'pretty' well known company. Nothing magical, a basic 6-4-4 veg nute...

I've gotta agree with cowboylogic here. I've had this same problem and based on the fact that you have yet to mention your pH and said you have used very little nutes tells me this is more likely a pH problem. Same solution anyways, just flush it with properly pH'd water.

My soil is still wet, and I use a self feeder pot, where your suppose to pour water in the bottom and the roots pull it up to the top, so if I'm flushing the water from the top back, into the resevoir aren't the plants just gona feed on it again? If that is the answer, should i basically flush water through and remove the excess water?
