Newbie need help diagnosing problem - Thanks in advance

How close is your light and at what strength you running it?

You want to aim for 80-84f

26 inches at full strength.

problem is ppm is a bad way to discuss concentration but yes id drop it. yeah na that's nothing to do with potassium but i could be wrong.

i think you are just feeding wrong. don't get so hung up with the numbers on the bottles. you are not trying to match them as in 5.5.5

equal parts of each at half the suggested ml the bottle says will do. if you're not going to use your nutrients how the manufacture wants then to be used then expect deficiency

using base nutrients shouldn't be complicated

This is not me trying to create my own feeding formula. This is a well documented method and many people have had great success with it.

I would either raise it 6" or dim it to 180-200w ish.
I fucked my plants up when Quantum boards first came out.
My plants in veg cant take full strength.

Best thing is to lower intensity and make sure your vpd is on point.

Lot of folks having problems trying to go too intense and it can cause issues that look like all sorts of problems.

Thanks for your reply. I did not know the lights could cause problems like this.

Some would call it LED deficiency but I don't know about that.
Higher air temps, higher root temps and higher RH seems to help though.

Its a weird thing but seen it myself and seen it on a lot of others grows.
Always seems to be in veg too.

would you recommend lowering my PPM as well?

It depends, im used to using EC to measure and it depends on what scale the ppm is measured.
I don't go over 1EC in veg if that helps.

Its a good idea also to allow your ph to swing up a bit to 6.1/6.2 range rather than keep it constantly at 5.8, it allows more availability to different elements.

I am using the 0.5 scale. So my PPM translate to about 1.9 EC.
I am thinking the excess nutes might be my problem.

In that case half your nutrients.

i read that to start with i say its a joke and its something i wouldn't waste my time on . but hay enjoy your deficiency if you wish to not use them nutrients correctly
