Can anyone help with my plants? is out wrong with them?

[Gareth Jehan]

Hey, does anyone know what/if anything is wrong with me plants they all seem pretty healthy, although different even though there the same strain. I've done grows before and the leaves were dark green in colour. However, theses plants (cheese) have light green leaves. There on veg 18/6, 600watt, 75-80 temp and I've successfully cloned from them. Am I just panicking over nothing. I will be putting them into bud next week, so just wondering if I could get advice if out was up.

All feedback appreciated

Looks like a magnesium defeciency. Yellowing of leaves with green veins in the leaves. Either needs higher feed or a dose of mag.

 

[Gareth Jehan]

Hey yeah, the leaves are not yellow there light green, also the veins and leaves are the same colour. Someone suggested Mag/cal and I'm using that with my Dutch go pro nutrients. Like I say it's just the odd leaf here and there and they look pretty healthy otherwise. Just can't understand why there pale green and not dark green and why they're different looking if they're the same strain.

Here are some clearer pics illustrating the difference and the light green colour

Pale green could be a lack of nitrogen.. Which nutes are you using

Hey, I'm using Dutch go pro it's my seventh week veg now. Everything I've seen on the internet or what people tell me differs a lot some say mag/cal some say nitrogen so not sure what to do coz they look alright apart from the colour variation.

Cheers

Or you could be bleaching them with the light. How close is it? Just a thought.

Hey yeah the light, until a few days ago was about 12-18 inch away because I thought the closer (without) burning them the better. Now there getting bigger I've pulled it to about 2 foot away. I've never heard of the light bleaching them, however this could explain how they look healthy but pale. Is it common to have the odd discoloured leaf here and there on an indoor grow?

There you go boss, theres your answer. Too much light.

Ya but not as much as you have. They will also yellow out more as you get into bloom, especially after about two weeks.

That's not bleaching, that's a deficiency..either nitrogen or mag
What's your ph numbers?
I've had that same issue, I upped my nutrient dosage slightly and it corrected the issue every time.

Right nice one pal, so u reckon leave the light a couple of feet away and they may darken in colour? When u say they will go yellow when I bloom them is that normal and ok? Like I say I've got me clones going now also, so don't want to bollox it up after two months of hard graft.

My ph is 5.8-6.0 in coco but I've been adding mag/cal 0.7 ml per litre. But u reckon it may be nitrogen the? I don't want to go given them the Dutch go pro + extra mag/cal + nitrogen isn't that over nutting the bollox of them?

 

[Alienwidow]

If they are bleached theyll never turn back to green. I run 1000s and i had a table where the light was four feet away from the tops. So i thought id make it closer, big mistake. They yellowed out within two days. I moved it to about 20 inches. Id say let the clones veg longer if you can and they will out grow the damage, maybe veg a couple more weeks on everything to get some new growth in there. Good luck.

Cheers will try all the above, like I say I don't really want to go adding nutrients here and there.

What ppm are you feeding them daily?

I'm no pro, but I know I've had that exact same issue twice during this run. I use Advanced Nutes which isn't high in nitrogen so when I upped the dosage the problem was solved. Judging from your ph levels its not lockout so it has to be a deficiency.

 

[Alienwidow]

If your ppm is at higher than 500 every watering you shouldnt have an N problem.

 

[Gareth Jehan]

Ok not too sure about ppm unfortunately like I say I'm a bit of a novice. But i do measure my nutrients correctly, don't over water, hours of light correct and I check the ph, which I thought would be good enough. How do I do this ppm thing?

Nah, it doesnt have to be a deficiancy, and theres no gaurentee its not lock out either. If hes not emptying his runoff and its reabsorbing it could be lockout caused by root zone saturation, not ph lockout. Theres always a ton of things it could be and with only a picture its tough to really diagnose any problem 100%. All you can do is try and narrow down the grower errors the best you can. He said his lights were at 12 ", now thats too close. Fix. Theres a good chance hell say he has no idea what the ppm hes been running is, so that needs to be taken into account. Plants dont come with dip sticks and its even harder through a screen to tell, so ya.
