SO got back into town this evening. First thing I did was check the grow. To my delight drip system worked without a hitch..... But I did notice something weird going on since I was gone. It seems as though the plants from about the mid point of table to far end(closest to back wall) have developed what looks like burned tops???? Only thing I can think of is nute burn??? And the only reason I can think of why only the middle to back of my scrog has this burning going on is because those plants receive more light from the reflection of the Orca Grow Film on the back wall. If you guys could please have a look at the pics and let me know if you think my theory is correct or not? Dumb me I decided to change my feed from 3 times during lights on to 6 times during lights on and never really got to test it before I left. Well I don't think I was getting any run off with my drip times and think thats the cause of the salt build up?
I checked run off this evening and it was showing 2.0-2.2 EC and PH 6.2. I then ran 30 gallons of 0.6-0.8 EC Nutes with 5.7 PH through my drip system and run off is now between 1.2-1.4 and PH 6.1. I adjusted my pump timer so that at each drip the pump will run for a longer period. I should get run off at each drip now which should fix the salt build up issues???
Other than these "burned" tops I did notice some growth in the 3 days I was gone so that was nice to see.
