The larger fan leaves will lighten but not like your photo. The burned tips are the very beginning of nute burn.....what are your numbers? These spots....looks almost like a water burn or insects perhaps? I'm not really sure but I know there are not part of normal blooming. Is it increasing onto other leaves or not?
PPM @ the moment is 1200, I have been keeping it at that since last week & maybe shouldn't have been adding nutes to the water I top the res up with. Although the plants have been drinking it at 5 ltrs per day. I will just top up with PH'd water tomorrow & then change the res again on Friday to bring the PPM's down unles you think I should flush straight away.
The brown spots are mainly on the White KC plant, can't remember at this point seeing any on the Skunk. If there has been some dew in the morning that could be the only way of water getting on the leaves. I haven't seen any pests on them & I give them a good scan 3 times a day at least using a lens from a 50x pair of binoculars as a magnifying glass. I'll have a thorough search in the morning on both sides of the leaves, but any chace you can give me an idea of what I am looking for.
hey JH you have a TREE in there. dammmm that looks great. keep it up bro.
1200 is good....you do have a good sized tree there...that shouldn't be too much ppm wise.....perhaps its from before. Those spots Jack......I really don't know...try this link and see if it has any info you can use. You also might try posting that pic in the plant problems sections and see if someone else can offer anything.

Cheers HC the Skunk at the back is pretty tall, I'm 6' & I need the step ladders to check the top of it.:jointsmile:
I had a good read of that link WH :thumbsup: . From its info it looks like the candidates are light bleaching, heat stress or a calcium def. Would have to say yes to the light bleaching as I'm closer to 150 W / sqr ft than the 75 W advised. Heat stress is another issue I would say is probable, but the time it would take to get a solution implemented exceeds whats left of this crop by my calculations & I have decided to defnitely get a tent, coolshade & extraction system for the next grows flowering stage.
That leaves the calcium def & it might be worth treating for that just to be sure. The guide recommends foliar feeding with dolomite lime. Where would I get this & is there anything I should pay particular attention to?
good looking plants!
Cheers evertking
Had a bit of a think about the PPM's Weedhound, the Skunks are quite tall but the White KC at the front is less than half the size of big bessie at the back. Its also showing most of the burn problems. So I changed the rez today anyway & didn't use as many of the budding additives. Left out the Vita Link Buddy as I'm using the Canna Boost & PK 13/14 combination this week. Once that all cycles through with the half inch left in the bottom of the tank the PPM's should be about 900 - 1000.
Good point that I didn't consider Jack....two very different sized plants....good call. Keep an eye on your ppms and see if they stay the same, rise, or go down. I have no idea where to buy dolomite lime but you can also use something called CalMag Plus which is made to replace calcium, magnesium etc in your nutes. For some reason.....that does not look like a calcium def to me (not that I could say exactly what a CA def looks like) so I'd be careful of adding anything at this point. Your plants look very good and that's when I usually "overhelp" them and screw things up. If you can post a pic in the problem section I'm pretty sure someone like Stinky or somebody will know what it is. Heat sounds very much like the culprit to me.
Week 11 & 42 days in flower.
Starting flushing today as the KC1 is now showing more amber pistils than new white ones. The skunk #1 doesn't appear to be browning off the pistils yet but I checked the photo on the site I got the seeds & it looks a more white hair than red hair sensi.

The nute burn seem to have been sorted & as I'm flushing now that should hopefully not cause any further problems. Still some light bleaching but unless I take out the ceiling the light can't get any higher.
Pic 2 is a comparison of mid buds from both the White KC (on the bottom) & the Skunk #1
Bit perplexed as to why the mids of the Skunk heave better development than the top of the White KC when they are at the same height r distance from the light. Maybe that strain just isn't very heavy on the resin.
They look great!!! :thumbsup::thumbsup: Looks like they are starting to fill in and swell there. Different strains look at end up differently so no surprise that they seem different to you. (plus the lighting) I''ve read that you cannot tell how good a strain is by the amount of trichs on it so don't go by that....some really strong strains have lesser amounts of trichs (so I've read.....)
Since you are flushing with ph'd water for several weeks I'm assuming you are not going to go with a flushing solution like FloraKleen or something along that line?
