Ikke andet for at prøve at køre rent vand med ph plus et par dage evt. Og så lad dem tørre lidt ind inden du begynder at give gødning igen

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

I can not take out of the tent to the darkness more than 4 at once and wanna hear your suggestions before I go with yellow sugar leaves or some amberish :D
I read something about harvesting immediately (not to crap the flower) when sugar leaves start to turn yellow and I have some! On the other hand, I saw some trusted videos that has some yellow sugar leaves. I want to ask you if you have any experience with this issue?

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

Not Nutrient Burn
Well I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

Leaves turning yellow with brown patches
I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.
