Looks like potassium deficiency from low ph or imbalance.nitrogen toxicity...did you change the nutrients when it started flowering (leave a bit in the bottom of the water can)? ...what is the temp, humidity and PH? nitrogen toxicity is when there's been to much nitrogen and it made it sick, water/flush it with water only(no nutrients)...pray
This is a leaf from my current...got a little hot in veg (the brown edges) but the yellow spotting? cant be root bound any ideas?
I've photoshopped the colour in the plant pic,
it got a bit warm, i have boosted the pk (pk13/14), PH is always between 6 and 8, all newer than the burn growth looks ok...at this stage.Looks like potassium deficiency from low ph or imbalance.
Ph of the feed or ph of the runoff?it got a bit warm, i have boosted the pk (pk13/14), PH is always between 6 and 8, all newer than the burn growth looks ok...at this stage.
higher PH is better for K intake??
So not root bound in your opinion? I did take some soil samples and it looks like the NP are are the medium/ high range. K is lower. PH is about 7. If I do flush with plain water do I have to adjust it lower than 7?Chronic overfeeding and watering. You now have a root or transpiration issues. Flush with plain ph adjust water and then let dry well it may take quite a while to dry since she is pretty rough.
Yeah use plain water phed to 6 5.flush 3x time the volume of the media. Then give a light feed of balanced nutrients maybe 400ppm and let the pot dry well before watering again.So not root bound in your opinion?

pH between 6 and 8??? That’s a really wide berth.it got a bit warm, i have boosted the pk (pk13/14), PH is always between 6 and 8, all newer than the burn growth looks ok...at this stage.

from what i can gather plants will better intake nutrients over a range 6-8 PH at different times, eg from 3 to 6 weeks 6.6PH is better...7 to 10 weeks 7.5 is better...(not the real numbers) ive seen a chart somewhere...so yeah you could (as with most) argue pro and cons of having static or dynamic numbers...pH between 6 and 8???

Sorry, i'm not sure what you mean?Ph of the feed or ph of the runoff?
There absolutely is a range and from what I understand, the medium is significantfrom what i can gather plants will better intake nutrients over a range 6-8 PH at different times, eg from 3 to 6 weeks 6.6PH is better...7 to 10 weeks 7.5 is better...(not the real numbers) ive seen a chart somewhere...so yeah you could (as with most) argue pro and cons of having static or dynamic numbers...
Yes different ranges for different nutrients, and I’ve seen a range of basically 5.8 to 7...but it’s usually pretty tight for the specific medium.from what i can gather plants will better intake nutrients over a range 6-8 PH at different times, eg from 3 to 6 weeks 6.6PH is better...7 to 10 weeks 7.5 is better...(not the real numbers) ive seen a chart somewhere...so yeah you could (as with most) argue pro and cons of having static or dynamic numbers...
