Using fox farm ocean forest and some prelite....think it was mirgle grow perlite.
I tried testing my run off but I don't think it was accurate. I used a rag to collect the run off and squeezed it out into a cup then tested.....like I said probably not acurate. Yesterday was my day to flush with water and this morning it almost seemed as though the already bad parts on the leaves died off even more. Not that it spread just killed those parts off quicker. Also I plan on transplanting tonight. They are about 19 inches tall and ready to be topped. if it's not ph problems should I see other signs?
It may very well be ph....I may have been getting it to close to 6.0 the last couple of batches of food. My only way of testing ph is by taking a sample of food and applying drops and matching the color. Guess I'll lean more towwrds green from now on.
You need to know the PH of the runoff. The ph of the water in the soil is what really matters. How much nutes are you feeding it and how much perlite did you mix in? How long have they been in the FFOF in THOSE containers?
Oh and your setup looks really nice, what size Floro fixture is that?
T5HO's?
You should pick up an electronic PH tester instead of using test strips. You need some degree of certainty.
Last, but not least, I would bomb the veg room with the lights off overnight. I do this now with every batch while they are in veg. Just avoids problems down the road from developing later in flower when you can't do anything about it.
