White Spots?

[bordercollie05]

I was just wondering if my plants are getting too much or too little of something. The new leaves are coming in very light green with white spots. This is happeing all three of my rhizome plants. My sword and r. indica are coming in normally.

Thanks in advance!

(I'm dosing KNO3, KH2PO4, and Flourish for micro. also have diy co2.)

when dosing EI, you need 30ppm stable CO2 otherwise you could run into problems wth algae, the white spots sound like a potassium deffieciency but i hink this links back to the CO2, not enough is being injected so the plants cant use all the nutrients?

enough K is usually added with the KNO3 & KH2PO4 but sometimes more is needed.

Someone else might be able t help

Should I add a second bottle for co2? The Co2 ran out two days ago and I'm mixing up the new batch today. Maybe less was getting produced as the mix got older. Would it help to make a new mix more often? This one lasted ~3wks.

get another, change one at the weekend, and one midweek, to keep a steady CO2 outpt.
