Question about the claw in soil grown plants

Hey guys, In the past I have grow my plants in hydro. Recently, I deiced to try a group of plants in soil. I am seeing the start of the dreaded claw on several plants. I have dealt with this in hydro finding it is usually from a salt lock and flushing with flora kleen. This group is in soil and has not had any nutes added yet so I am wondering how to handle the situation. The plants have a nice light green color and do not appear to have an abundance of nitrogen. It should be noted that the plants are in small 5" square pots as I was testing soil verse's hydro in a perpetual SOG. Any thoughts?

Admortis, I am by no means an expert, in fact still a noobie, so dont take my advice, but lets see what the experts think of my advice first.

Firstly, I think I see the leave that is clawing, and it also looks like it has a burnt tip? I had something similiar, my soil was to hot for my seedling, but it pulled through, and everything came out fine with my plant.

Seeing that it is one of the lower leaves, I wonder if you are not in the same situation that I was, the soil WAS maybe to hot for the baby, but now that it pulled through, and is older, the nutes in the soil is doing it good, and helping it grow, hence it looks good, no increased clawing, and the claw is only on the bottom older leaves.

Being that these plants are very close to each other in a sog style grow it is hard to show all that I see. Many of the plants have inner leafs clawing and several have new leafs on the tops showing claw. The room is at 75 degrees so I am not sure how the soil could be hot. Soil is really not my thing I grow in hydro; I was simply running a comparison test to see how the soil would measure up to hydro. If this was hydro I would simply flush with clean water and FloraKleen and reduce the nutes. I can always simply toss them but I hate to just toss out 12 pretty little girls that have already started to bud.

Claw in soil stems from too much N. If you catch it early and the claw isnt too far along its treatable. A flush and reduce the N you're using.
Claw will affect trich production and also extend your harvest time. Its no fun at all.

Your Claw problem is not too bad...in fact its hardly an issue...but the leaves are dark green...too much N. Cut it back a bit and you should be fine,

I don't see anything to be worried about, those look to be kinda small containers though, remember soil needs more room than hydro, i'd transplant to at least a gallon square pot, don't forget to dust the plant's roots with myco when you do

Hey greasmonkeymann, the pots are small on purpose. The whole purpose behind the test is to see if I let them become root bound in the same size container as hydro will they perform the same if provided the nutrients they need.

Hey Admortis, I see some experts chimed in, so I think you are all good. Just wanted to clarify, by hot I meamt to many nutes, not the temp of the soil

doesn't look like too much nitrogen to me, that's a normal green for indoor plants, in my opinion

Yeah It is more normal than not. But the advent of clawed leaves, even though only a few, points to only one outcome...too much N.
But I take back the comment about it being too dark. There's a range of exceptable green that is normal...and yours falls within that range.

I understand that, but you are proving a point already known, that is that soil plants need more room, if you are purposefully making them rootbound, um, then why are you surprised that problems are starting to occur? Seems a lil silly to me...
I mean they look ok to me, but you ARE going to have problems in that size....
ive done SOG with just organics and soil, and the minimum for good results is a gallon square pot. In hydro you can go much smaller, that's the whole concept/allure of hydro, it was developed for places with no soil or very little room. a gallon will net you much more (usually at least 10g a plant)

Personally i cant see any nute burn at the top of the plant so i am not sure why youd have the claw, also i notice they are in flower so they may have the claw because you no longer need the amount of N contained in the soil....my advise (many dissagree) is to flush the pots with a flush agent such as florakleen and 1/2 nutes. at least twice the volume of the container........then leave it for a couple of days to dry out and see how your plants are looking.

thats what'd i do but i grow in coco.....

please note i got savaged for suggesting this on a different thread lol

flush? With half nutes? What purpose does that do? I mean this with respect, I have ZERO time nor patience for internet arguing. Just fail to see the point of that.
also, off topic kinda, plants absolutely need nitrogen during flowering

it should remove any salt build up and also lower the N content whilst not depriving the plant of food....its easier to add than take away i suppose....ive done this for my plant and it worked well BUT like i said people think im crazy .....no arguing here just doing things a different way
