New Grower My very first indoor grow....

[AndyBotwin]

Things are looking very nice, Mellow. That yellowing is a tough one. When is the last time they got some veg nutes and/or calmag (Epsom)? You probably have just enough time to give them one more shot of food to hold off the yellowing for a couple more weeks. But even if you can't stop it, you seem to have enough fans to get you through another 2-3 weeks til harvest. I personally am not a fan of going with a foliar spray this far into flower because I don't want mold or to smoke anything that's been sprayed on the buds. Whatever you do, just remember that the damaged leaves won't ever recover, so keep an eye on the green ones to see how she's doing.

Dude, you have got to be absolutely beside yourself. Once again, Muddy has turned a new grower into a very capable producer. Your grow is absolutely rockin'! :head:

MY, you know me, I'm prone to ignore stuff on my plants that makes other people nervous when they see it on theirs.

But, I'm almost positive you have a potassium deficiency or lock-out. If you have checked your pH, and it is good, you might want to add a bloom fert with a high last number... for example: 0-0-10 (N-P-K = Nitrogen-Phosphorous-Potassium). The first two numbers don't have to be zero. You just want to make sure you have a larger last number (or last two numbers). You don't have a problem that's going to kill your grow, but that yellowing is showing up a little bit earlier and is a little more extreme than I like.

Looking good my man! To me it looks like you're pH might be a little low. See where it's at and if it's low, then feed as Joe said, along with the cal/mag. Don't remember if you got any PK13.14. If not, you should get some. Soil less plants under LEDs seem to use a lot more nutes and the extra P and K is usually needed during flower.

How tall are they? The node spacing looks good and you should end up with some nice sized buds.

No, this has been a group effort, getting MY going. It sure helps when you have a willing student.

gooooOO Blackstar!

 

[Rebel]

Not that I need to lol but I will agree with Muddy and Joe Dirt. You will have some nice buds on your hands soon MY! Those girls are much to be proud of!!

 

[Mellow Yellow]

I ordered some cal/mag and it'll be here soon. Thanks for all the help guys. They seem to be doing really well. I guess the buds should be filling out soon...

My soil ph is about 6.0 and holding. The next watering I will put some higher PH'd water in and see if that raises it. I figure I'll try ph'd water between 6.5 and 7.0 if this sounds right.

 

[Muddy]

You're in the soil mix? If so, then low pH is your problem. At 6 cal, mag and P are being locked out. If you've got some hydrated lime add a tablespoon per gallon of water, shake it well and water. That will help to raise the pH of the soil.

 

[Mellow Yellow]

Ok, I'll get some hydrated lime. Thanks Muddy.

Yes OF & HF 50/50 mix.

 

[RollerofDoobs]

I had the same problem with my OF, pH was 5.9-6.1. I just corrected with a mix of water and baking soda (7.5pH) today. I will be hoping that both of our treatments work! Next time we gotta mix some lime in with the soil to make it easier on ourselves lol.

that 7.5 ph was on your water right doobs? not your soil
