help 7 th week and getting worst

hi,
I'm using big bud
giving pure rain water, I have mixture seeds, I guess its about the type of plants, 3-4 of my planst are having problems, one of them is serious. yellowish leaves were goring up so I flush 5 days ago and now;


some of them are really green and of them is really bad what should I do? Should I harvest and save those flowers?

First check the roots asap. Carefully pull the plant from its pot and quickly check the bottom of the root ball. If the roots are seriously swirling around the bottom edge then that's likely the problem. If the roots are fine, give her a high-N fertilizer mix with some of everything else as well.

I check the roots, they look healthy, a lot of roots at the bottom looks like white healty and swirling. what should I do?

how long into flowering are you, it is normal for the leafs to turn yellow close to the end of the life cycle.

loosen up the roots at the bottom with your fingers and put in a bigger pot,then do what mothers finest said.

all of my plants are in same size of pots. why this one? is it about the type of plant you think? they are in 7th flower week.

You already checked the worst one and saw what might be a problem. Now do the same to the best looking one that was planted at the same time, pulling it out and checking the roots. If there isn't as much root swirling than you can be pretty sure that's the cause of the one plant's problem. If the roots are the cause and the plant doesn't have long until harvest, you can just add 6" or so of soil at the bottom of the pot and gently put the plant back in, letting the top of the root ball stick out of the pot a little. Always hold the plants firmly by the very base of the main stem with your other hand supporting the root ball. An assistant would be useful when adding dirt. Always be as gentle and careful as you possibly can when pulling the plants and/or transplanting, most especially during flowering. Be very careful any time you set the plant down, like when putting it back in its pot. Set it down very gently to prevent bruising the roots.

if you in seventh week bro your likely almost done unless its a pure sativa. i would give them a real good flush. 1 gallon pot=2 gallons of water run threw it. get your ph dialed in, and water for a week or two and harvest.
the affect of the plant seems to be some sort of micro nutrient. because it looks like its worse towards the top, which indicates micro and some sort of nute lock out. your buds look a little small for week seven, which also is a sign of nute lock out. when you flush your plants real well, make sure your ph is absolutly perfect. imbalanced ph is typically what will cause nute lock. good luck bro, the rest of those plants look great.

thank you all, I flush it few hours ago, if it won't work I'll harvest it tomorrow. because the disease is fast. some pistils even looks like they are gonne dry soon. by the way, Ph level of my soil is under 5 what can I do? this is my first grow.

your local grow store or garden place will have basic PH UP and Down. all kinds of organic or not. just get something simple, and adjust your water to 6.5-7 (I am at 6.7 all the time) every time you water. with or without nutes. if you are using nutes.....than nute your water first before you PH your water. sometimes you dont need to adjust if you are using quality nutes.

good luck brotha. do you have a journal on your grow? you should start one, you will get tons of help. just keep it updated so people dont get bored.

oh, and you PH under 5 is 100% responsible for any dysfunctional growth you have going on. get that dialed in the next go around, and you will see considerable change in your plants behavior.

yup 100% i had the same problem, had a cheap ph meter, said it was perfect everytime but all the research i did on the internent pointed to fucked up ph but my meter said they were fine... went and bought a better ph meter and sure enough checked the ph and they were all 4.6. im my opinion ph is the most important factor

ok thank you all, I raise the ph with some calcium tablets. now it's between 6 and 7. I hope I can save that girl.

nute lockout. ph out too low at 5 . too late to mess around now its nearly ready ,just flush.

your root bound and have salt build ups but if your 7 weeks in flowering it doesn't even matter because your almost done anyway

it's not getting better should I harvest?
