So I'm running current culture systems. Using their cultured solutions nutes. Running about 1lpg air manufacure specs (38lpm pump on 30/35gallons water)
Ph is very stable, ppms are under 500 (they recommend low mom's and I've had plans kill it in the first 2-3 weeks of flower at only 200-250 ppm on 500 scale)
I run 0 ppm RO water with uv filter. Grown soil for over 5 years and killed it, I've been learning these sustem for about a year now and have all but this deficiency figured out... Hopefully after this I can really dial it in. They are a dream to run from ease standpoint one figured out.
I use cultured solutions A&B
Cultured solutions mid boost
1ml per gallon of calimagic
And have been using .5ml per gallon of pro-tekt silica on fresh res changes.
I do a res change no later than every 14 days ripping off with nutrient water.
The last harvest the deficiency got so bad that it rurned parts of the upper buds brown. Looked burnt.... Pain having to go over all the buds so closely to cut the burnt tips off.
Current culture guys said my ppm was too high because I was running twice as much air per system before I took their recommendation and pulled a pump off each system. They said at over 2lpm per gallon it was almost impossible not to burn with any nutrient strength....
Anyways this round has been grown with just the one air pump rated at 38lpm...
Here are the pics, the deficiency usually spreads in past experience.
Also the cc guys say not to use more than 1 ml per gallon of calmag....
The last pic shows some plants 3 weeks behind at 3 weeks flower (they were the ones crushing it on 250 ppm)
I don't see any deficiency till around week 6. Mostly see it on the tips of the plant and new growth.
I also don't get the overall yields I know are possible... I honestly did better overall on soil although some plants yield over 8z...
What do you think it is, I'm at a loss! Maybe the ppm shouldn't go higher than 400 with my air input?!
Current culture guys said with my air situation I should use 25% less than the high feed chart which I have.
Add the whiteboard pic shows ph & ppm are stable... No offence but please don't cone in if you are unfamiliar with these systems or are a noob
Thanks guys sorry for the ramble but these are my babies and I take more pride in them than you know
