Leaves started changing colors

I have been adding CalMag for the past week and a half. I also added 15ml per gl. I have talked it over with my lady and we are going to get a chiller in the next week hopefully.

Why dont you bring your Ph down to 5.8 everything Ive ever read suggests that this is the optimum Ph for hydro. Ph6 is the upper limit for hydro Ph and might be causing this problem.

6.0 is fine for hydro, it actually can get up to 6.2 and still be fine.

the most recomended PH level for hydro is 5.8-6.0 no offense but i highly doubt that his PH is the issue. but like i said before im no hydro guy but everywhere you read claims it is fine so i would like to think EVERYONE is not wrong.

Oh, I'm sorry I thought your PH was right.. you're adding too much calmag indeed ! and I do believe it's PH related. A solution at 6.0 if 5 times more alkaline than one at 5.5, and the plant needs all those ranges while 5.8 is considered the sweet-spot for best availability of nutrients. You've been adding 15 ml of calmag but you've never allowed them to absorb it as calcium needs a PH of at least 5.8 in hydro to be absorbed, that's why they're getting so much Nitrogen and very little Mg-Ca, btw white burn tips is caused by to much N. This is all happening because of your water PH. Your leaves are practically yelling at your stubborn attitude. I don't mean to be rude, just let you know the objective evidence is there in the pictures.

of at least 5.8 or a max of 5.8

no pun intended just making sure you typed that correct.

ok just looked at a chart and at most 5.8 for calcium uptake and at least 5.5? right. sorry im not trying to give the wrong info here.

edit: sorry for misinformation

heres a chart for refrence.

thank you everyone for info and help!

The little lady and I got a chiller 3 days ago. And hot f#cking damn! Everything is just going nuts!!! The growth jumped by inches from once we added it. Everything is a wonderful green again!

But once the tips burn or turn yellow can they heal back of are they doomed to slowly fall?

I'll post pics soon

also water temp is at 67f`
HP is at a solid 6.8
PPMs are at 1030

Still in veg state. I could get ready to start flowering now or should I still wait?

 

[Thedillestpickle]

as long as the leaf isnt mostly dead the green parts will stay green and still do their job. The dead parts of the leaf will never heal but thats fine(not ideal but its ok) as long as most of the leaf is still alive. Older leaves near the bottom of the plant do sometimes die off and this is normal especially if there is not as much light down there. Everything I say is based on reading thousands of posts as I have very minimal actual growing experience.

ok seriously im no hydro grower but these fukin yahoo's on here are so quick to diagnose i dont even think they read what you typed just looked at pics and tossed out some bullshit diagnosis to make themselvs fele like they know what they are talking about.

PH is good?
whats your PPM?

you did the right thing by draining and flushing your system when you accidently OD them but you cant leave them with no nutrients, unlike soil hydro systems need to have nutes from day 1 as plain water does not offer these nutrients (maybe a little but in tiny amounts)

i personally suggest checking your PPM and slowly raising it daily while maintaining propper PH, ALL of your plants look like they are suffering from deficiency because they have been in plain water for 4-5 days with no food.

get a second opinion on this as im no hydro guy but from what i understand of the system this is your problem. also you need a good PH and PPM meter for hydroponics, get them, they are worth it 100%

I completely agree. You really need to maintain the ppm in a hydro grow. Take this from experience. LOL. done quite a few, back to soil now, like the taste better and just overall more simple. F*** all the complicated BS. I fell for it too. You can grow big ass plants in soil just as well as in hydro. You just gotta know whats the best method of a soil grow. Personally this looks like a Nitro Def to me. Starts at the bottom and affects the stem and big ass fan leaves first. Just keep up the feed and you'll be just fine, but remember not to overdo it. You will start to muck things up more when you try to fix things to quickly. let the plant do its thing after you feed it for a few days.

Hell man I've had plants grow in 7.0 and higher in some cases. They did just fine. PH is really over exaggerated when growing. Temps, constant feed, and keeping a clean system are the most important things to remember. Ph can affect the plant if any of the other aspects are off, but root rot can show up with a perfect ph, the plant can lock out nutes due to temps etc. Check out the marijuana growers handbook and do some ph research on cannabis online. very interesting stuff. I find it hilarious that when the people start hydro the first thing they pick up after nutes is a PH meter. I have grow for almost a year and never touched one without issue. My friend brought one over jsut to see what I was running a few times and he was pissed to see how well my plants did with a so called "high PH". LOL

PH at 7.0 in hydroponics? show me your plants to see how well they're doing. or STOP right now trying to give people TERRIBLE advice. I dear to say PH is the most important thing off all as NOTHING is of use when PH is out of whack, neither water, nutes, lights or whatever.

Im only a month into growing and I know this BS because with a pH of 7 youll have deficiencies showing within just days... so whatever dude your info's useless to anyone that actually wants healthy plants

 

[Dragon's Fire]

here are some updated pics of my girls.

my big one, she still have some yellow. But it never gets crazy. But there seems to always be a some. Mostly the tips. (Is this normal? Spec after having issues?)

This one is doing the best out of the 3 clones, as for no yellow and what not.

seedling 1,

seedling 2,

WTF is that Spot!? ;( This is my last clone. She always has a yellow one or two leaves, left over from the issues. BUT!!!!!!!!! The spot... Can that be normal? I do not see no bugs around nor anything that look like eggs, Used a x5 magnification hand held. So I am lost, yet again x.x (next two are her)

PH is at 5.8
water temp is at 67f`
ppms are at 1050

 

[maps84]

They look good, Some are showing signs of slight N toxicity so you'd benefit by lowering a tad the grow nutes.

 

[Dragon's Fire]

It breaks my heart to say I lost my 3 clones to root rot :/ Once it hit I didn't get it fully in time to save them. But I did make a fairly good butter with them. ALSO the 2 little seedling are still going and about to harvest maybe tomorrow. They are stunted though. Rot almost got them too. I washed the roots well and some how with almost no roots both girls didn't give up.

Can you re-use the roots? If they are healthy of course. Like asparagus crowns?

 

[Dragon's Fire]

Also I started using the Great white line of micros and hydrozym works so awesome. my cutlings are also into flowering.

Thank you again everyone for your help!

pics come soon
