Hi everyone!
I'm growing out the C99 F1s from MOS Negra right now. I'm 25 days into flowering with two plants and one looks awesome, the other I can't tell what's going on. That particular plant has two different colors, a dark green and a lighter green color, very distinct. Maybe someone with some grow experience will have a clue or remeber something about growing these out.
Running a drip system into hydroton with a screen above, for the first 20 days I've had the PH steady at 5.8 with an EC of 1.6-1.7
One plant continues to look like it's underfeed, the leaves under the screen are going completely yellow but without any tip burn or damage, just fading and falling off (Maybe a PH issue? Nute lockout).
600w HPS air cooled 18" above plants, temps between 75F - 84F with RH around 40-45%. It's dam hot were I grow now and keeping the room any cooler is almost impossible.
My first scrog so I thought maybe it's a lack of light under the screen but that's not the case, leaves that are getting plenty of light just below the screen are still going yellow but others right beside them remain just fine, mostly the older leaves are having the problem.
I track EC and PH daily along with TDS and temp of my res. About 7 days ago I decided maybe the nutrients were to hot but there really was no indication of that from the other plant which looked perfectly healthy (same seed pack). Dropped EC to 1.2 along with PH down to 5.4'ish. Seemed to have slowed the yellowing a bit but still not convinced I have figured it out yet.
Wondering if these plants could actually need more nutes than what they are getting? An EC of 1.6-1.7 seems high compared to other strains I have grown but I was told they can take almost anything given them. I am not really concerned for the remainder of this grow, not going to expect great results first time with this strain but I have a ton of clones and would like to sort it out at least for the next grow which will have 6-9 plants under a 1 meter square screen.
I know pictures, pictures, pictures. I will try and get some uploaded in a day or so. I'm at work now and just trying to get this out there so I can start to figure this out.
It looks a lot like an N deficiency, has for a while. Last flush and res change (10 days ago) I added a little more N but didn't really change anything. Trying to let everything settle in, lower PH, lower EC, a bit more N in the mix. But after 10 days it hasn't really changed anything, still dropping 2-3 yellow leaves a day, bitch will be bald in another 20 days! Not really but seems like that.
Any thoughts would be appreciated. I've really tried everything. By the way, thought it might be over watered, but after a conversation with my guy at the store, he says it's almost impossible for me to overwater with the setup I use (dutch buckets with hydroton). The buckets hold an extra 1/2 gallon of the nute mix in the bottom at all times. I use drip rings and prevous grows only feed them 3-4 times a day. After my talk with the grow store guy I increased the watering time to 15 minutes every hour which hasn't changed a damn thing (been 15 days of increased feeding). Christ maybe it's too much at this point, cut it back???
Thoughts please.
