leaves appear to be a sneaky someone's dinner

Thanks smokey. I am flowering now, end of first week. I'm using a 1/2 dose of Liquid KoolBloom w/ the GH nutes so I am hoping that will take care of any K or P lackings.

Yesterday was our bump from 50% to 75% nutes and the resulting PPM ~850. Strongest they've seen yet so we'll see how they do (I hope they take a liking to their new light). I also flushed with some Clearex. The front-right plant was drooping all its leaves, today it seems to have perked up a bit. This is the problem with growing multiple plants in a single res.
well you are smart enough to buy the clearex. hopefully you get to the pint where each one gets their own res-you can completely control their size and their yeild to a degree. more plants=more salt build up-I noticed quite a few posts about GH and excessive salt build ups. they will need the extra strentgh of nutes first month and than you can back down abit.

While you're here smokey, if you don't mind, I know the general school of thought for room temperatures is ~15F change from day to night, min temp about 65, max about 80. I'm finding my night time temps can drop as low as 55 in the room, res temps may hit 60-62, above-h2o root zone temps ~66-70. Is this cold air temp hindering growth or otherwise harming them (lights are out btw at night)? It might be for 3-4 hrs in the early a.m. for example. Max temps are 80-85 at the cannopy, 70-75 ambient room temp during the day.
are you growing in my grow room? b/c ur temps are just about exactly as mine. All res temps are 60-65-If they hit 70 I lower with cold water. My experience is they like it a bit better on the colder side- they can run at higher ppms with less issues-just tons of dissolved o2 in there. Any lower may be a problem. Root zone temps in check-just make sure you are able to somehow circulate the air in there 2x a day. My daytime temps run 75-82, with co2, and usually around 67-68 at night and probably 60ish for 3 hours between 3-6. I would say 55 may be a bit too cold for them, although sometimes I wake up and they look the happiest they have ever been. Remember the internal temp of the foiliage can be as much as 10-15 degrees higher. What I did was purchase a low wattage electric heater from home depot for like 30. It displays the current temp and you can set it for 1-6 hour cycle-I set at 62 and it never comes on. If you are noticing slow growth and some purpling, may be too cold. if not and they are growing just fine, than you prob be ok. Experience will tell you what's best. All seems very much in line. Just make sure you are getting plenty of fresh air and circ in there which u prob already have.

Ideally I'd light them for cheaper & cooler at night but I don't have a good light seal around the window yet, working on that for the next grow.

It's called Citrus Sweet or Berry Sweet by Botanicare. Damn holy shit. Like I have been seeing 20-30% larger finished bud mass and being about 1-2 weeks ahead of flowering sched. All without additional CO2 to boot. This is talking after several grows with the same bud. Basically is like molasses but for hydro. Carbs, sulpher and mg. Like a diff that I did not even know was possible. Something to look into. Makes the smoke a little like fruitty pebbles. barely noticable but noticable.

Sweet, awesome advice thanks dude! I will seek out that heater -- good stuff. There is a slight leak of light through the blinds in the window (partially covered), but standing in the room at dark you cannot see the plants at all, so I assume they will be ok. Thoughts on that? Absolutely no direct light on them at all, but you can just faintly see the room outline in the dark.

jees, tough call on the light. the most they can have is one half of one foot candle of light-foot candle being the light from a candle ina 12x12 square. I would def seal up that window tomm. Some black garbage bags and duct tape. Or if you have acess to the lights that are close, can you switch em to green lights or fluors? green is ok as they dont absorb that and reflect it back. I mean they obviously flower in outside with the light from the moon, but for me, always better to be safe than sorry especially if it is an easy fix. Look up some threads around these parts-they gotta talk about it.

Thanks for the reco on the flower enhancer. I will check that out, sounds like a must-have! My local hydro store guy has been working with me on this setup so far, and he recommended this bottle of "Gravity Flower Hardener" from Humbolt. Any experience with that? He swears by it, in very small quantities. Since I already spent the $$ I might have to wait to experiment w/ the Bontanicare stuff. BTW, are both citrus and berry the same other than the flavor they impart? They seem to have both.

Havent heard about the humboldt-what's in it? And I think the ingredients are the same for both Citrus and Berry.

Thx again. Hope we're not getting too o/t here.
