Problem...PLEASE HELP ASAP

[smokeyMcPOT]

I'm growing some skunk 69's and some MMM(Magical Mystery Mix). They're in 1/2 promix 1/2 perlite mix. I added a little D. Lime to the mix b4 planting. They were vegged for 8 weeks and put into flower and have been there for 3 weeks. I water when the pots are dry by weight and I use all FoxFarm Nutes...Grow Big, Big Bloom, Tiger Bloom(not yet) as well as the ChaChing Open Sesame and Beastie Bloomz. Also a little Superthrive when first transplanted. They're in 3 gallon pots and the PPM of the waterings has been around 500. I add a little Hydrogen Peroxide to my water (read it helps the plants get Oxygen to the roots) My PH is around 6...not sure been using the Pet Store Kit..Meter is in the mail now..Cant wait.

My concern is the bottom older leaves are yellowing and browning in some spots. I've went through just about all I can think of to try and fix this with no luck. It seemed as it were a N problem....but also could be a Mg problem. Then there's Phosphorus and Potassium...

Can anyone give me a hand with this...I've looked through Stitches Post on plant problems but havent been able to pinpoint the problem.

I forgot to mention that they're under a 600 Watt digital HPS. Light is about 18 inches from tops. And room temps range from 70- 82 with light on and 55-65 off. Humidity is around 35% at all times....Thanks

you'll note that the lowest leafes with the lowest finger count are first to show the def signs.
Its a normal process, the plant is getting rid of them, seems like either they aren't getting enough light or nutes in the later case you could up your feeding a bit.
To me it looks like Mg and N, more than one def, your nutes could be too low.

Loose the H2O2.

Hey smokey, those plants are looking good. Like mace said, it is normal for a plant to start losing leaves like urs are in flowering.
A bit early for it to be losing leaves like that but you should be ok.

spash any nute water on them lower leaves during watering ??? tis would also cause your problem. word of advice becarefull using all them nutes together if you mix big bloom tiger bloom and beastie tiger n beastie will give ya large ammount of P for the plant. thought open seaseme is for veg and early sexn of the plants do you have the proper feeding scedual



almost forgot tiger bloom is best to start off using at 1/4 strength for 1st wk if plants like it up strength to 1/2 2nd wk so on so forth till full strength, but watch them closely when ya introduce a new fert strength. some plants love everything ya give em some dont 1's that dont ya have to back off on the strength of the nutes and find the happy medium for them. im unsure how many grows you have but the 1st few are allways a learning curve. figure out what works what dosent and get your grow dialed in g/l grow on buddy

How dry do you let the media get before rewatering? Are you loosing alot of leafs?

I dont use the Foxfarm Schedule to the "T" more like what they seem to need at the time. I let them dry until the pots are light to pick up. And yes there has been minor nute splash when watering once or twice. I only use the OS in veg as Mr. Mo had said. I'd say only 3-4 leaves have fallen off or I have taken off . Not too bad yet...just wanna fix b4 I get a real problem. Thanks for all the info!
