I’m growing cropking auto trainwreck... so far grow has been going good... I’m growing in 5 gal fabric bags... I started out watering til there was runoff while plants were young but noticed that it took along time until pots where light... started watering enough to where it was need every 3 or 4 days...so no run off.. I’m in week 4 about to be 5 They are in preflower.. 2 days ago I gave them good watering and noticed my runoff ph was 7... and ppm in one was 3200... and pm in others were around 1200 to 2300 ppm.. so I gave them a good flush...been watering with 6.3 ph but I flushed them with 5.8 and every single plant ph was 7 and would not drop... in each plant last gallon I ran thru had light nutrient feeding with 700 ppm... they seemed to love it and growth took off.. and they looked great today I went in and noticed these leafs with spots
I mean it doesn't really matter what nutrient it is because more will not fix it. You found your problem. Maybe run some drip clean, sea green or enzymes with water and get good run off the next 2 times at least but wait for the media to dry well in between. The products I listed will help flushing out the nutrients. Get the runoff down the a light feed
I would say one of those products with a good amount of run off. Then a flush with water next time and follow with a light feed after flush. Your going to see more issues to come but now it's about correction so it will get worse before it gets better.
I'm a new soil grower so see what others say but that's my view.
Ok so I know that i have made a mistake... while being in a hurry and didn’t have time... I noticed 2 leaves with powdery mildew... and i looks my plants over everyday.. and also noticed 1 spider mite so I went and mixed up baking soda. Oil soap and water... well being in hurry I sprayed them and placed them back under the light... they were healthy and beautiful the day prior and I come inand today and they look like this
