First off love this forum and glad to now be a part of it myself. Been researching here and on other sites for a few months now started soon as i heard my state was going medical lol so me and my wife decided to get our cards she suffers from severe vertigo attacks and i treat anxiety. We started our grow in a 2.5x4x6 homebuilt box had a chance at 3 types of genetics via bagseed once it hit stretch we knew it was chemdog wich via trial and error i found is a very picky feeder, so now were approaching harvest 6 days into flush waiting on full cloudy trichs. Question now is how long into flush should it take for leaves to begin to yellow ??? Any and all help is greatly appreciated shoulda mentioned were in dwc under a diy 360w cob led light
P def could be caused by adding calmag. Calcium competes for uptake with phosphorus and potassium and can actually bind to the phosphorus creating Calcium phosphate, which is insoluble in the ph ranges we deal with. It will precipitate both elements out as a tan coloured sludge that will build up in hydroponic filters. It doesnt take much excess free Ca for that to happen either.Yea definitely agree on too close to the lights it stretched so bad i had to add on a foot to get the cieling space i have and with the ca deffiency at week 5 or so i knew that was there now once that ca damage happens ahould i have cut those leaves off, and ill tirn the light down a bit when it comes back on tonight big thanks for the diagnosis. And the p deffiency has to be due to the flush right???
