I have 3 plants. 1 female 2 unknown and they are in the second week of flowering. They are growing in a dwc with netpots, hydroton, and rockwool. CFL lighting (my one female is about 3ft. Its taller than the other two plants). I used a different nute brand during veg and switched over to FF trio beginning of the 12/12 cycle.
So I have a question about feeding in DWC. I am using FF trio for my DWC grow and the plants looked like they were nute burned after I followed FF suggested serving size for the first week of flower. Now I have the res filled with 6 gal of water and 25% of the serving so 4.5 tsp of Big Bloom-.5 tsp of Grow big-1 tsp of Tiger bloom.
My question is if they were nute burned or over-fertilized how long does it usually take for them to start eating again? My ppm after feeding the 25% serving was a 340 at a .5 conversion factor and my tap water has a ppm of 140. So I have noticed in the last few days that the ppm is rising (now at a 420) but the PH has been a stable 5.8-6.0. So it seems as if water is evaporating or they are drinking water and not eating any food. My temps are 77 f for the room and the res is 68-73 f sometimes cooler.
The growth seems to have slowed but the newest growth seems healthy. The fan leaves immediately below the new growth have brown tips/saw blade edges. Some of the tips have curled upward while others downward and a few others are twisted as well as curled.
Here are some pics: THE YELLOW IS FROM THE CFLS if i turned them off it was way to dark to see.
I need ideas or solutions. I don't want them to die. I have been trying to see what I am doing wrong but idk. I am willing to read so if you know where I should look please point me the right direction.
