Get a beer, this ones a bit wordy. I have pictures but am not including them because they tend to mislead. So, if I've explained this thoroughly, and you know your stuff, maybe you can help me figure this out.
I've got some White Rhino, Mint and an unknown strain all about (5) weeks into flowering. Growing in soil, 4 gal bucket, then 10 gal, under a 1k HPS.
40% humidity
Low temp - 75
High temp - 82 - best I can do without AC
Plenty of continuous fresh air
The first couple of weeks in the veg stage everything looked fine, then I started getting deficiency signs that I never really pinned down. The new growth started to turn lime green, the leaves lost their luster and just sorta drooped and/or curled under (rams horn) like they were needing water (not like they were nute burned, then again I'm not really sure), but when I tried more water it had no effect, so I let the soil dry out a bit until there was obvious stress/drooping from lack of water. A quick splash and they came back to their previous state, but never looked very healthy.
After a few weeks of making some small tweaks to get them to respond I ended up just giving them a good flush and fed them with a good Ph buffered fert at about 600ppm and about a week or so later they really sprang to life. The new growth greened up, the leaves perked up and they really came around with all the leaves looking nice and shiney and supple like a healthy plant should look. After another three weeks of some pretty heavy growth I'm starting to see similar signs.
While they aren't turning lime green, growth seems to have slowed and the leaves are just starting to look dry again and are showing just the slightest bit of drooping, they're just not nice and shiney like they were a few weeks ago.
These are now in 10 gal pots and have been getting a regular dose of a Ph buffered bloom nute at around 600 ppm.
I water them about every other day where they receive between 2-3 quarts water. They have also received some additional Maxicrop, Bat Guano ans molasses once during the last three weeks and occasionally some plain dechlorinated water (no chems). Each watering translates in to very little run off as I'm concerned with over watering (which I might be doing anyway, but the soil isn't soggy prior to watering), so just to be safe I'll be flushing this weekend.
The soil is a nice mixture of potting soil. compost, chicken manure, perilite, course sand and I even threw in some extra Hydroton I had laying around.
Ultimately what I'm trying to figure out is, what's causing the leaves to lose their luster? Is it fert/salt build up in the soil?
Too many nutes? Too little nutes? Too much moisture, or not enough? I suspect that a flush and fresh nutes will have similar results as before, but I'd really like to know what the main cause is.
The only change to the nutes have been cutting back on the Nitrogen the last week and a half, but the plants aren't turning yellow like they're deficient. I just wish I knew what it is/was that keeps the leaves shiney and healthy looking. The leaves just aren't showing any other symptoms, yet.
I've studied a number of deficiency charts, pics and graphs until I'm blue in the face, but nothing I've tried to address in previous grows, or this one, worked better than a flush and fresh nutes.
Thanks,
