Nitrogen Deficiency During Flowering and becoming extreme

I'm no soil guy. But, I would just mix your nutrient solution down to about 5.3-5.5 with some ph down, for a few feeds. It could damage the roots if lower. calibrate the meter to be safe. After a few feeds, it should start pulling it back to a good spot.

Not sure about lime, but if it will only bring it to neutral i think it might not do the job.

Since you are in soil, make sure not to over water. Wait to give that lower ph feed/watering until it actually needs it. The plant doesn't look bad or anything, just some yellowing. Over watering would do more harm than having your ph high.

I have little experience with soil indoors, so if a soil saavy poster in here says 5.3 is dangerous for soil, listen to them, not me. Pretty sure it is fine though. And, will help your plant out, given your current 7.4. Sounds like sulfur will do the trick too, but i dont know anything about that.

But remember... if you feed your plant 6.3, and the run off coming out measures to 7.4, then that actually means that your soil ph is a bit higher than 7.4. The runoff test isn't all that accurate. Just an easy way to check quick. Vindicateds idea of a soil test will get you a better idea, if you want to go the extra mile.

It looks nice, what is it?

Just because a plant is flowering doesn't mean it doesn't need nitrogen...just not as much. I'd give it a bit.

The strain is Grandaddy Purple. Thanks everybody for your feedback and positive and ecouraging words. Will post more pics.

Any all purpose plant food labeled high in nitrogen would do.

I wouldn't give it to much nitrogen at this point. Some yellowing at this point is not such a bad thing. I would think that fixing your ph problem would stop the yellowing from continuing, and you would be all good.

Bio Thrive Grow would fit in with what you are using now if you are set on giving them some nitrogen.

I think fixing the pH is what i should do, only because im noticing other nutrient deficiencies (lockouts probably) such as phosphorus (purple stems), copper deficiency (curling leaf tips).

Hi I was given some cuttings that were almost yellow, I even thought they were a new strain. Ayway, I hung a milk container above them with a yeast/sugar mix to give them extra CO2, I alsofed them seaweed extract and......I pissed in the water I fed them with. They all turned a very healthy looking green. In fact the person who gave me the cuttings had some of his own on the go. They were older and more established and more than twice the size......6 weeks on, mine had grown bigger and healthier than his! so the morral, piss in the water!

That's disgusting. You are foul. But you do have somewhat of a point. Phosphorus was first isolated from human urine and it was one of the first elements to isolate if I remember correctly. Still pretty disgusting.
