About a week after flowering started the fan leaves started to bend over in what think is the typical "Claw" pattern, but the leaves around the flowers are drooping dramatically like an upside down canoe. So when I read the sick plant guide, it sounds like I have to much nitrogen and not enough phosphorus. Is this right? Arghh. Since I am using tiger bloom and big bloom at the same time I wasn't sure what to do. Please help! This is my first real grow and I am kinda lost. Any help is sure appreciated.

Yep. They're getting the claw. Too much N. It's easy to do with Tiger Bloom. That stuff is pretty hot, as is the FFOF. The first couple weeks of 12/12 are tricky. I used a Tiger on a few grows 3 years ago, but stopped using it. It does jump start the flowering .....but it's easy to over do it. You should be able to flush it out. Don't use it again for a while. After flushing, the new growth should normalize, while the clawed ones will stay that way.

I think 3g per 4 plants with only 250w is too easy to overwater, which is what it looks like. The 250 is not bright enough for 4 30" tall plants, sorry dense looking clones(!), in 3g containers.

yes, too much N, I would flush with ph'd water and then chill out a bit with the nutes

Thanks everyone for the replys. I did a through flush last night as suggested. How long should I wait to start adding nutes again (I was doing half strenth, next time I'll do quarter strength), or is there a sign that I should look for?

 

[mexilandrace]

I would maybe just water with water next time, then the next time hit them with a really light fert dose and see how they respond.

In spite of the other opinions....

In the pics I see your tips look pristine.... so not likely to be too hot...N


The claw imo is a transpiration issue....

 

[Mr. Greengenes]

"The claw imo is a transpiration issue...." You're not the only one, that's what I said too.

2 weeks into flower huh?.
thats the key here IMHO this is a cal mag issue.
