New grower, K problem?

Okay, so it's my first grow and I've read the stickies. I am hoping experienced eyes can confirm my guess. The lower fan leaves are starting to get "papery" with brown spots on the edges, but not always. I have 4 600w hps lights, promix HP CC soil (mostly peat moss), I'm watering every three days or so as the soil dries with the mills line of nutes. 2 weeks into flower. Any input welcome.

With the info you've given and the question your asking im going to say no it isnt a K problem. Thats old lower fan leaves and the problem your seeing is from weeks ago and your just now looking into it. Not a big deal in other words. Focus on the new growth and environment and I would recommend getting a decent microbe product in the line up or at least research microbes and what they do.

And with out seeing the whole plant I am going to go out on a limb and say that the lower stuff isnt getting much light and maybe some lollypoppy is in order.

It has recieved some lollypopping, I am using mammoth P. I forgot that bit. My bad.

Plant look ok to me. Mammoth p is a microbe product that just focuses on solubilizing P. Might want to get a well rounded microbe product maybe. I would use mammoth p at the end of week 3 - 6 or 7 only due to the price.

You can actually culture mammoth P! So I'm using WAY less than recommended, but getting good results. Let's find that link...


I think mills has a microbe line, ill look at that before my next grow.

Right on, I know. If that is what you do thats ok but you want an army of different microbes in there. Variety is the spice of life.

If you brew the tea with ewc then you would get a variety. Lots of tea recipes out there if you dont and just brew the mammth p by itself.

Again the plants look ok to me so...............................................

Gotcha, Thanks for your help.
