Experts needed please!!! Papery, bleached leaves..

Hi folks

I've been trawling around trying to find out what's wrong here. The plant is growing like crazy, but the leaves are curling a little, and they're papery, not lush like I'd expect. In my inexperienced, noobish way, I've narrowed it down to the following possibilities...

1. It's too close to the light (about 5" away from a 400W HPS in a cooltube - thermometer next to the plant has never gone over 80* and sits at about 78* constantly, with a fan blowing across the plant 24/7)

2. It's got complete nute lock-out...seems to be suffering symptoms of many kinds of deficiency. It's been in the ground - Plagron Royalty Mix - for 21 days, and had very little in the way of other nutes (I have been watering a little with VERY dilute nitrozyme). When I measure the pH of the run-off (and I know all the arguments surrounding that), my water going in at 5.8-5.9 is coming out around 6.8-6.9.

If anyone has any thoughts or ideas as to what the problem is I'd be really grateful. Cheers in advance.

You're growing in soil and you feed at a ph range of 5.8, isn't 6.5 the ideal ph for soil, seems to me you feeding is too acidic for soil, could be nute lockout.

Hey man, thanks for jumping in. I should've qualified that..you're right it's low. I was going for about 6.2 at the beginning of the grow, but bought it down because of the high pH of the run-off. It seems a lot of folks are happy running a little under 6.0 in soil.

I'm beginning to think she's suffering from a case of underwatering whilst being too close to the lights, but not ruling out your nute lockout just yet..

:peace:

I'd move the light away for a week and see what that does. Probably triple your current distance then slowly bring back down. It looks bleached to me.

If you put your hand where your plant is does it feel hot?

*Disclaimer* You asked for experts.. I am no expert. Have a few grows though.

I'm gona go with ^^^^^DeeTee^^^^^ and it looks like she's really wet, wait till the pot feels lite and soil is receding from the sides (shrinking..there will be a little gap between soil and pot edge) and from the leaves it also looks like your light is way too close...bring it up to at least 18 inches or so...(wow how many times have I said or heard this one)...put your hand over the plant and if your hand is hot then so is she...good luck and welcome to RIU...

Wow, thank you everyone.

Ok, so... no it's not too hot. I learned the 'hand test' a while ago, and it's fine - corroborated, like I say, by a thermometer that is slightly more under the light than the plant is.

It's not wet - or rather it is, because I'd just watered her. I think if anything, she was too dry. Bit embarrassed about that one, but I've only been watering small amounts, which tonight's research suggests is a bad idea.

Riknstein..18 inches? Really? I'm an utter newb (but a sound engineer, so I know how the inverse square law works), but surely I'd lose too much light that way? No? Will you be mortally offended if I just go with 6 or so? Can I ask if anyone else has a similar problem with a 400W HPS at 5 or 6 inches (12-15cm)?

Thanks again for all the replies, guys, appreciate it. :peace:

most likely lockout and to close to light

Hey man, I've not seen those 4 multicoloured charts before - thanks!

And are you thinking the water is too...low in pH? Despite the run-off being in a good (ish) range?

i dont even put my 150 w hps at 5 inches...150 w 7 inches
and your plants are too small to give em that much light...will just cause more problems than good!

keep lights way back for awhile.... than over time...slowly lower them as needed

ps. your welcome

most likely over watered or burnt from light or soil, you are killing it with too much of something, rather than it is lacking in nutrients
cant see how it could be any deficiency, it is too small to show drastic signs of damage due to deficiency
i can assure you they can get much bigger than that on plain tap water EC .2 in hydro and show no deficiency at all (still completely green)

peace

Huh. Didn't know that about being too small to show deficiency, cheers for that. And the general consensus is that I'm killing it with too much light, so nice one man. :peace:

Added to my original post a few posts back. She'd literally just been watered, so you're right! You agree with lime73 about the bleaching being because the lights too close?

Im not going by the soil as being over watered its the way the plant looks.
And yes I agree its bleached,been there and done it! And its from the light being too close!
Move light up,and cross fingers.
I went out of town and mine grew into the light,was gone for 5 days,and the person looking out,Did not do a good job.

Iron deficiencies are very uncommon as long as the pH is kept below 6.5 (5.7 for hydroponic or rockwool). Too much Phosphorus can also lock up iron. The best thing you can do is check the pH of your system, and then flush the system with clean pH'd water that contains nutrients at half strength to start, then start working your way up to full nutrient strength. It's worthwhile to note that iron has a tendency to react with many other components of fertilizer solutions and can cause other nutrients to be locked up from the plant. When supplementing your plant with iron, it is often necessary to not use fertilizer for that watering. If you are supplementing with iron, make sure you first read the label of both the fertilizer and the iron supplement you are using to minimize any problems.

PS : Water once every 3 days

Don't worry m8, most common cause of problems for new growers is loving them to death (over watering over feeding, general fussing lol, lights too close)
you have to learn to let them grow and stop fussing over them, with practice it will come
weed plants for the most part are very hardy/sturdy despite all the talk of stress in thread after thread after thread :wall:
stress is a cover word for "grower error" lol

less is more so to speak
good luck :)
