I need HELP ASAP, my plants are sick :(

See the attached image, my plants ware all healthy 2 days ago, and now this strange things begin to appear on some of the leaves.

What did I do wrong, what can I do to save them?

that looks like some kind of deficiency, theres a good
post on mara. plant problems somewhere on here, it even has picks with it

Over nuting.

It cannot possibly over nuting - I have fed the plants only 2 times, started feeding in week for with 1/4 nute strenght

looks like a Mg and Calcium deficiency. check your Ph, most nute deficiencys are just Ph lockout. also: don't over water.

sure looks like nute burn, i would recheck your water ph with test stips if it good i would definelty flush them

the leaves mostly damaged are those facing the light, so I am thinking it might be some kind of burn from the light? the leaves on the other side look much healthier

does it look like a burn from the lamp on the pic I posted?

Edit: i lifted the light 15 cm up, will get a ph tester tomorrow and test my nute solution, if things get worse tomorrow I will consider flushing them, I hope it's not too late to save them, they just started making buds, will be a shame if I lost 5 weeks in vain

Hey Driver, a couple of guys told you nute burn and then you shut them down, now what would you like us to say and then we'll say it. The problem with your plant is whatever problem you think it is. Next time someone takes the time to read your thread and post an answer the proper response is, "Thank you".

hey smart guy, if a guy writes to me go and jump of that cliff" is that the way to go? don't be an ass would you?

I didn't shut anyone down, I just said it cannot possibly be nute burn, my plants are 5 weeks old, and there is no way 1/4 strength nutes will be so harmful

tunyturtle might be right thou, Ph problems are much more possible
also I get problems only with leaves facing the light, and no problems on leaves that receive only indirect/reflected light, so thats another thing to keep in mind

i got a ph tester and will check my water and food solutions next time I feed the plants

the main thing is the plants didn't get any worse and seem stable for now

a lot of 10x to all the people who cannot live without it, even if they didn't bother to reply to the thread

I don't think it's your lights, burned leaves look different from that. Like others said, I'd look in your nutrients, probably something compounded with the ph of your water. Even a small amount of nutrients mixed improperly can result in nute burn.

yep, ph is my primary suspect

I also think, I MIGHT have poured some FOOD solution on the leaves, and when nutes are exposed to light and heat then tend to burn foliage... so that might be it

anyway, I brought my light up, haven't fed nutes since last week, and next time I do it I will be more careful

I think I will increase the strength as well, but first make sure PH is ok, cuz 1/4 strength seems a little weak for plants that are pretty much mature

yes it CAN be nute burn man listen to all these people telling u what it is...

why even ask if your so smart on the subject...

your plants would have loooked alot healthyer had u not

nuted the fuck out of em u shulkdnt even use nutes for a few weeks..

when a ganja plant grows outdoors naturally do u think
some1 comes along with some tiger bloom to put on them ???NO

so just take the advise people give and say thank you

dont be a complete asshole
