Chemdawg Yellowing crispy downward leaf curl

robz · Feb 25, 2011

This girl has been in flower for 3 weeks now and has started to develop this leaf problem. I was hoping for some quick advice. I'm growing in FFOF soil & I ph check with every watering and Ec at 1200ppm. I have also noticed it on my Chemdog girls that are in veg. Temps are steady at 79-83. Any advice?

What nutes are you feeding for flowering...I'm thinking possible potassium issue but need to know more.

Some growers are saying lack of nitrogen in bloom, if you notice that Advanced Nutes run higher nitrogen in bloon stops leaf loss, at least this is what some master growers are saying seems about right, other wise you just going to lose yellow leaves in bloom.

you are feeding to heavy and your starting to burn em, after those crispy tips , comes major salt build up effect

Ok, I'm assuming you're using the liquid form of the Big Bud...from what I see with your nutes your N-P-K ratio is really out of whack. You don't have much N in there at all, I know that the big thing is to pump your plants full of phosphorus in flower but you still need the nitrogen too bro. As far as your P and K, I would try to get more K in there during early flower then switch to a higher P to K ratio at the end of flower. I think you need to pick your poison with the bloom enhancers and I am pretty sure that AN advises growers to cut out the bud blood by week #2 of flower if they are using it in conjunction with their other bloom enhancers. IMO you are really throwing your ratios out of whack by including that in your feed schedule. On top of everything, you are growing in a fairly hot soil in the FFOF to start with...how frequently are you feeding? That's a lot of shit to put into a soil grow man, no telling how that is all combining for you, have you had success with that line-up before? Right now your plants don't look horrible but I would probably still flush and cut out some of those heavy hitters you have and maybe things will balance out a little better over the next few weeks.

I've used the Advanced several times, but this Chemdog seems to be less forgiving then my other strains. I only use the bud blood in week 1-2 of 12/12 like it says to. I flushed last night so I guess I'll back off on her a bit on the nutes.

dont give up bro chem dialed is insane. w0nkanobe had it super dialed and it looked craaazy. he used lucas formula though.i'd get the ppms down to 800-1000 and see what happens. also ffof contain lime ph not needed so much. looking at what ur using looks to lack n. cal mag should sex it up

What I see indicates a magnesium issue at the top of the list. A foliar feed of MgSO4 (Epsom) at a rate of 1/4t/gal water will tell you quickly if it's a toxicity or a deficiency. Otherwise, I think laz has most of it sussed there.

Oh I'll never give up! I flowered one 8 weeks ago only a foot tall. My friend said it was the best smoke he's had in a very long time. She will be fine.

Yeah, that's exactly how you do it man...push each strain and see how it reacts. Some will be pickier than others, I have a brainstorm right now that has been extremely picky to light and nutes. Just have to treat her a little gentler than the others and she is responding well to the added attention. Try singing to her bro.
