had the other message in drafts and after I posted it, I read this.just be super careful what inputs you add like Mr sauga has stated , it becomes a big overwhelming mess then your completely on the ropes
Potassium deficiency can be caused by soil pH, extreme liming or calcium rich areas of fields, lack of soil oxygen or true soil deficiency.
Next can be (p) excess it can cause a zinc, iron then mag def
if you use a ph down to ph your water , with your soil amendments, and with the (p) boosts the plant it will take up the ph down also (phosphoric acid) depending on how much it takes to get in range it can cause problems in excess ,they take up more cal than (P) so never over do it
the best thing to do is water to 20 percent run off at a ph o 6.4 let dry out almost completely and water again
, what is your tap water sitting at , and is it hard or soft water ?.
get some seaweed extract and look up foliar feeding leaves , it will put the nutes straight into the leaves and your roots can have plain water for a while to see if they perk back up, and the leaves colour up again ,
if the plant still looks hungry after a few watering's then hit it with a good base water soluble nutrients
Any ways that's my little part done
Thank you for insightful response Nutty.
The last 2 waterings have been 6.5 and 6.4 pH, and I have let the soil get dry every time. My tap water is soft I think (17ppm). I really don't want to spend any more money, I am already 3x over my budget with this grow... so I can go ahead and do the foliar feeding - is it a big deal if I skip the seaweed extract?
Hmm... I actually haven't watered her like I said. I decided to wait a little longer and let that soil get dryer. I do sense it's a lockout of some sort, but can't figure out what caused it.Great close up shot too @NuttyProfessor . I'd have to agree that it looks more like K def now. Hopefully @parrajara sees your posts and makes adjustments for that. No harm in the extra calmag, but if it's a lockout then it won't help.
