Im having an issue where my leaves are curling inward. Not that its rolling downwards and in, but the sids of each leaf are curling downwards. The fan leaves are not doing this, the leaves around thebuds that are growing up each arm the main stem. The plant itself looks fine. Nice and green, no nute burn that I can tell, but I havent been able to test the runoff water b.c the pot I have does not have holes in the bottom, I did make some, but water never comes out lol, which is why im about to get a bigger pot so I can test runoff ph.
I cant see it being a real problem, After I come back Ill take some pics so yall gave give me your $0.02.

Thanks all
Hello EnhAnceD,

I'll take a shot at some answers, I'll probably have to check myself tommorow, I'm realy working under a handicap right now.

1) at least once a week depending on type of medium, type of nutes and other factors. Dutch Master for example recommends feeding to reccomended strenght one day then palin water next two time you feed.

2)yes, ph'd water allows the nutes in soil and in the plants cells to be used

3)signs of nutes lock out, or certian deficiencies.

Important to understand you need to run the correct PH based on what medium you grow in. In general terms soil should be about 6.3 (+/- .2), Pro-mix abot 6 (+/-,2) and for RockWool 5.5(+/-.2). But always check and see if your nutrient mfg recommends and use that as a starting point.

And a shift from what the PH in is, to what the PH out is a good thing. The shift allows for beter nute uptake since differant elements get used better at slightly different PHs. I hope this helps, hell I hope it makes scence.
