hi
ive got a clone 1 mounth old in soill, 26 degree c, ph about 7, 40-50% moist.
ive started feeding her a 2 weeks ago, once a week. the spots started few days back and i think the top leafs are a bit pale.
ive looked in the forum and it looks like this is a potassium deficiency that is caused by ph lockout

need a second opinion

thnks

The stems look pretty dark aswell,it very well could be a K deficiency. Heres a guide i like to use when trying to first determine a deficiency.

Also, what are you feeding her? A 20-20-20 fert should be good enough to get rid of the deficiency. If you start to get yellow tips then its likely nute lockout. I dont think you would have to flush, if you thinks its the ph try slowly adjusting ph throughout a couple of days so you dont hurt her. Goodluck!

1st of all your plants have deficiency of everything because they are hungry, plain and simple. Are you feeding recommended by the MFC ?

How's your soil in aeration ? I did not notice perlite from the aerial pics you posted ?

What wattage are you using right now ?

This is it, the main factor, IMO.

My advice transplant your plant to a lighter (Add more perlite or similar) and let the soil get almost dry between feedings. I have no experience with LED, therefore I cannot say they will help you right now. Your LED is red or blue ?

thats not over watered thats a ph issue with to much nutes you can see the nitrogen claw, i would flush her well and let her be.

second, dont go by what the bottle says you need to find what works for you, your better off with a low and steady supply of nutes then quick sudden bursts, plants like a schedule and get use to it very quickly.

it was a ph issue, my ph meter had a malfunction and the ph was about 4-5. now the ph is leveled. i flushed her. the leafs starts to get a good color.by "nitrogen claw" u mean the long "finger" in evry leaf?
