hi all!
My previous grows went bad. There was something killing the plant. I discovered it was not chlore as i thought but the tap water itself was the problem. It contains something harmful for the girls.

Well this new grow goes super good. I changed tap water for air condirioner condensation water i collect every day.

Anyway, my plants are on 3rd week flowering and the older leafes are looking like this. Just the ones on the bottom where light doest rich powerful anymore. But, it looks weird though.

I just give them Phoenix for flowering. (it is a solid type nute that disolves in the soil when watering. It is organic) Its just a good soil which contains NPK.

What do you think it is?

Pinch the leaves going bad off. Between the leaf and the main stem.Don't pull them off at this point. Keep all dead plant material out of the container. All of it out faithfully.

Its not overwatering. im sure..

Leafes are getting pale and yellow in the middle of the plant. Right under the light. The ones that are towards the edges of the indoor cabinet where there is less light are beautiful green....
I dont understand what happens...

I was just gonna post that pic lol, and if it the top leafs near the light that are doing it... It could be that you light is too close. What light are you using and how far is it from your plant?

are you adjusting the PH of your water to? could be nutrient lockout. I adjust mine to 6.3-6.5 every time I water.

its not normal!

its either ph lockout or over fert....

flush with ph'd water,feed at 25-50%
I would leech it first until you get a good run off and matching what you are putting, after it dries then do the nutes like man said. My tap water is 7.2 so I buy bottled water at 6.2 and the ladies love it.and I'm in soil

It's nutrient lockout mate thats why he asked you the question lool. Yes it's to do with your ph but it's too much nutrients causes lockout, if your ph is not right when feeding nutrients that causes a lockout as far as I understand.

Never heard anyone using condensation water to water their mj plants. But i do know this, water that sits in a condensation pan collects bacteria from the evaporator coils, try using rain water it's much better for your plants, that's all I use.

Your better off with tap water instead of A/C water, it collects all sorts of nasty things you may not want in the medium/res .

I post accurate references so those coming and reading this after the thread dies can actually learn. I hear people throw out "lockout" like it happens quickly or can be undone quickly.

The GIF in this is worth the click to see if you truly do not understand WHAT it is and HOW it occurs. You will note water pH is not in the formula.
Thank you for pointing that out although I'm not using nutes in my grow I was under the impression that improper ph levels would create lockout!
