Bubba Kush and the Claw?

Hi guys,

I started this new batch of bubba kush on Saturday and Im trying to figure out if it's getting the "claw" or not. Not sure if it's overwatering or nitrogen toxicity. From my understand bubba doesn't need much N but the whole leaf is curling not only the tips.
I popped them in Saturday night and gave them a soak of PH (5.8 r/o water. Then fed them their first feeding Sunday morning. I knew this was too much but I'm running Rockwool and wanted to get some nutes going.( 650 ppm on a 500scale)

Also this is my first time using Grodan blocks vs quick drain's like pargro. Is it easy to overwater with these? I know dry down is essential and want to make sure I give equal amounts.

anything will help!

Thanks,

As someone said to me " you can never over water.. you can water to often" best of luck, its going to work out for ya.:leaf::peace:

Thats overwatering. You can go longer between waterings with rockwool since it holds water for much longer than most other mediums. Whats your schedule on waterings/feeding?

That's the feeding schedule, I'm using AN jungle juice instead of GH. Also using roots excel. No aroma just diamond nectar. H2o2 and cal mag , 2.5ml.

Basically just feed/watering once a week at this young. I'll post an update today as they seem too look a little better but closer to N tox now(only the tips curled)

UPDATE;

Rockwool feels light feels somewhat damp but can see dry spots on bottom(don't want roots to die). Should I
think N tox now and flush tomorrow when I feed and drop micro down to 3ml(since its 5-0-1), keep grow at 5ml and bloom at 1ml. Here's some posted pics.

Also, my res seems to be getting a lot of algae fast. This is about 3 days with 2ml h2o2 and no res cover(not much light hits under tray/stand).

anything will help tonight, I'm going to start tomorrow morning if I don't hear anything back.

Hey Guys,

Here's an update, it's Friday now, they've been in for 6 days and a majority are looking better. I stuck with what everyone said and just let them be. I have not fed/watered since Sunday. A few still look rough. They are the larger or taller of the batch and wonder if they are in need of feeding or just to dry more. Also when would you recommend I feed? At this rate I think I'll feed those who look good tomorrow or Sunday. I'm getting a lot lighter of color in the plants. Also def getting the claw on a few. Should I flush and then feed or feed with lower N.

Thanks

i really don't see anything pointing to a nitrogen toxicity, you'd really need to pump them with a lot of nitrogen to get any sort of over fert imo..
what's your humidity looking like?

Temp 73F Humidity 50%. Heres a pic which make me think N tox on a few. I'm more concerned on the really droppy ones as to if they need to be fed or dried out more. Any suggestions?

i still don't think it's n toxicity, they look like normal green colored bubba leaves to me.. the curling can just be genetics or over watering like said earlier. i'd just keep doing what you've been doing, maybe back off on the food a bit if you feel like they're being over feed.. do you see any burning in the tips of the leaves? that's the fist place you'll see nutrient burn if you're over feeding them..
i'd just keep with the program, and keep an eye on them.. so long as they're growing and generally look happy, other than the small bit of clawing, i'd not really be too worried about it tbh.. sometimes it's easy to love them to death, trying to over diagnose a small problem..

perfect! I'll keep it at 600ppm again this next feed (sunday) and let them dry a few more days. I've got some burnt tips but its only on a couple. My biggest issue is the droopy ones ive got about 8 total who haven't pulled back from the over water like the rest even tho cubes are pretty dry as well. The original cubes seem to be somewhat moist but barely. I guess the Rockwool just stores a lot of water inside without showing it? Thanks once again!

Overwatered buddy. just dry em out a bit. ME personally i do not think they are N tox'd. usually most of the leaves will be all dark green. your new growth is light colored green. if it is more of the whole leaf then just the tip it is just overwatering. I wouldn't worry about the N. What i would do? Let them dry out, flush them good, check your ppm run off/ph if you like the results then follow up with a light feeding on your next scheduled feed. Watch to see how they react. then just follow up based on that afterwards. Are you giving them any micro nutes? calcium-mag? copper.. etc any hi-brix? Dont over stress on it or just doing 100 things trying to fiqure out a problem you dont have. Alot of people have done it and it can and will just cause more issues for you. your plants will tell you if something is wrong outside the normal over water or underwater, which i think is all you have right now. overwatered. good luck man best of luck to you. heavy yields brother

Right on! Thanks for the feed back. I'm feeding 2.5ml of calmag , 2.5 roots excel, and 5ml of diamond nectar. I'll up as they grow though. As for flushing and feeding do these Grodan blocks drain excess? Or should I be only feeding/watering a certain amount? The last blocks I had I just drenched them once every few days(being quick drain).

I don't understand , how can u overwater in hydro

It can be done with watering your rockwool too often since the medium doesn't drain/dry out as fast as say vermiculite. But the opposite can be said of Hydroton since it holds almost nothing as soon as its drained it can be watered. Plus it matter with what kind of system you run in hydro. Flood/drain and drip water farms are going to have different watering cycles.

I figured out my problem. I was running way too much roots excel at 2.5ml. Dropped back to the recommend .5ml and they bounced right back with vigorous growth. A couple are still gathering back but are definitely showing great improvement.
