1st Grow - Week 4 of Flower Did I overnute?

[cheezytaterz]

Pics below. Week 4 of flower. I know having fan leaves yellow and fall is relatively normal. But I'm a bit worried as some of the "bud leaves" have started to curl a bit. Did I overnute? Or are my lights too close? It seems like the leaves are turning after from the CFLs. I have them super close to the bud sites (1-2 inches). Should I move my lights back a bit so the plants can breath? I have two fans blowing on it, one oscillating. Any advice would be super helpful. Thanks!

I've been doing 15-30-15 nutes at 1/2 strength once a week (which is every time I water). Tap water that has set out 24hrs, and the soil has dolomite lime in it.

I personally would not be concerned. I have a similar setup and my plants started to yellow and eventually turn brown and curl up about halfway through flowering. I attribute it to the buds pulling the nutrients and water from the leaves. The leaves will likely continue to become discolored and dry out the later into flowering it gets. I did notice that on my indica based strains did not have the same issues as my sativa based plants.

Thanks for the input. Glad to know I shouldn't be too worried. Anybody else got any insight?

Yes its nute burn
Or either ph lockout
Plants lose the green color LATE in flowering
Not week 4

U say u water once a week.
When you water do you make sure there is some run off ?
Does it seem like your buds slowed down or even stopped filling in all together ?

Yes, there is some run off. It's usually relatively clear but I haven't PH tested the runoff. My buds seem to be filling in alright. In fact, they've probably filled in more over the past 4 days than anytime yet. They really did some good swelling these past couple days. Should I be worried and/or trying something new?

On the next watering id just give her plain distilled water and make sure there is some good run off
Then id start feeding again @ 1/4 strength and work your way back up after that .... just my opinion .

Just flush em out. It can't hurt and always helps!
It does in fact look like you have some kind of lockout going on.
Also, dolomite lime is great for balancing really acidic outdoor soil, but in potting soil it would probably bring it a bit too high. It also takes all winter in the dirt outside to break down into a useable state.
Go to the local pet store and get a ph test kit that goes around the 5-7ph.
This will cost you under five dollars and will let you know whether you need to use more acidic water.
1/2 strength may be a bit too high for food. Not sure what you're using, but most non-ganja-specific nutes (and even the good ones) come in way too hot, plus the salt content in your water makes it even hotter.

Looks like some tasty little nuglets are going to come of that when all is said and done! Now that you have the grow bug, buy a good ph tester and TDS meter. They make life easier, and more bountiful

Thanks for the advice.

I'm using Miracle Grow Bloom Booster 15-30-15. Not the greatest, I know. But best I could do around here on a budget. I've read that using it at 1 teaspoon per 1 gallon is alright on a weekly basis?

I'm going to do a PH test before my next watering. If my PH is normal, I will not feed. But if it was PH lockout, and I adjust my PH, should I then keep my past feeding schedule?

So I tested my PH before adding any nutes and I'm at right about 6.8 or so. After adding the nutes, however, the PH seems to drop quite a bit (Around 6, maybe below). Is this normal/ok? I went ahead with a regular water with nutes yesterday and the plant seems to be alright. Only concern is that the oldest "sugar leaves" seem to be yellowing a bit. Thoughts?

Nobody thinks it's any kind of deficiency though (Phosphorus specifically)? That's the only thing I'm worried about; giving it distilled water one week and it getting worse because it's actually a phosphorus deficiency. Thanks!

Update: I flushed with my last water (2 days ago) ~6.8 PH with no nutrients. The plant seemed to respond well growth-wise, but I'm still getting yellowing and curling all around her.

Pics below, any advice? They buds seem to be ok, but I don't want it to suddenly turn on them. (Thursday will be 6 weeks in flower)
