One question stitch I have for you...does fish tank dechlorinator remove the hard minerals in the water too. If so can it cause the problems my plant is showing.
Fishtank dechlorinator adds sodium to the water. Never use it for your plants.
Throw that fishtank chem crap away, its much better to just aerate a barrel of tap water for a day or two to remove chlorine. If your tap water has chloramine, you're pretty much stuck with it, because the fishtank treatment chem is worse, causing unwanted sodium in the water.
I think I'd be more concerned about those top leaves curling tubular like they are in the picture, heat stress or maybe the sodium salts ???
but anyway...did you flush the plant with this 'sodium water' too ?
Feeding twice a week. But one is at 1/4 dosage 1/4 ounce pbp flower, 1 tsp LK, just added 1 tsp calmag first and second weeks. Going into the 3rd week so I bumped her up to at least half ounce pbp flower with 2 tsp LK no calmag this go round. The other feeding is an extremely watered down version of a normal feed that I give her. The soil is fox farms ocean forest with light warrior mix 1/2 perilite. PH testing is done with a pen not the cheap ones its nice...direct in soil type. The leaf is a lower fan. As far as water goes it tap...dechlorinated and ph buffered to about 6.9 to 7 the pbp brings it down to 6.8-6.6.
Ok so I made a new mix of nutes... 1/2 oz of pbp flower, 2 tsp LK, and an advanced feeding of calmag which was recommended at 2 tsp. The PH of the mixture this time was at 6.7.It has been 3 days since I flushed with a gallon of water. The pot felt relatively light, and the roots are more than established. I fed with 2 and a half solo cups full of the mixture. Enough so just a little was in the drip pan. So now I will wait and give it 4 days of no watering to see what she does.
I'm just about beating my head against the monitor here, bouncing all over this thread trying to figure out what ratio of nute concentrates to water you are mixing. I mean, you mention quantities (in more than a couple posts) of pbp etc but never say how much water you're mixing it into ??
Is that per gallon ?
