I do have the vertical style Phillips but I thought they are hotter than running horizontal I only have a couple grows with them I have a lux meter and it says like 22,000 directly under bulb at canopy

Nope, that is the benefit of the vertical fixtures, is that you can run them closer to the canopy. If you think about the bulb itself, it makes sense too.

You should be ok at 20" then.

Ok thanks not a lot of people running them it does seem like anything closer than 18 is to hot you said you run yours at 24 do you have doubles and what is the highest you have ran them and still noticed growth

Mine is currently at 30" because I have two little ones just coming into veg, maybe a week old, and I don't want to stress them.

I am currently using the Vivosun fixture, which based on my research, should be used at 24" from canopy. 20" is too close in some cases, but other environmentals come into play I'm sure.

I started my seedlings with the light at 36". These CMH bulbs are strong!

Yep seems like I keep moving them up here is a good question for you 3 days into 12/12 came downstairs check wood stove and saw light bumped rspec timer supposed to go off between 8 and 8 just shut them off sucks should I let them get 2 hrs dark and back on schedule or should I run a whole 12 off also If I did run a 12 off how should I feed through it usually hit them once 6 hrs in dark and every hour and half when lights on which is supposed to start at 8 est

I think what you are saying is that the lights came on early? It is very early in flower, I would stick to your schedule and try not have happen again. Keeping schedule you had before is best I think.

No they never went off just shut them down now should I let them get 2 hrs of dark

So I just ran a 22 hr lights on oh well can't be any worse than feeding at 4.5 and 7.5 they have seen all three lol

Seems like no worse for wear they are happy I am finding some holes that means a bug right nothing is flying around and I can't find anything under microscope here's some pics of the holes what do you guys think it is

Day 5 22 hr light cycle doesn't seem like it did any damage still yellow bumped up to 1.6 and 15 min flood 45 min in between floods

Is this mold closest plant to uv bulb started yesterday 3 20 min burst mid day 3 ft away

Couple more pics if it's mold shouldn't uv kill it also close to fan and have been really low humidity levels having to foliar spray to keep some humidity so I can get over 70°

Bump

So I sprayed the leaf with to water and rubbed between fingers whatever it is didn't wash away

Ok so looked through microscope without cellphone and it is burn from pure uv it's 4 feet away from closest leaf so 5 min on 4 times and watch

Day six flower I was told need to count days after 22h screw up bumped to 1.8 ec 15 min flood half hour in between floods seems like a lot to me but they seem healthy just don't like the yellow

Bump

Hey homie what is your flood schedule

My pH tanked and all stores are closed should I stop flooding them they are in hydroton and pH is 4.9 I don't want them to dry out

Update photo cmh went out over week ago still waiting on new light they seem healthy ec is now 1.9/2.0 trying to back off on floods but they seem to go yellow have been up to once every two hrs and as much as once an hour I think I'm getting knack of pH isn't swinging as bad thank you homie I do think they are hungry cuz I don't really see burning tips

So this is also my first grow. To me it seems like you are over correcting your issues and making new ones. I'm doing dwc.
