 I'm growing in Coco. 6 weeks in Veg. COGr Nutes. ph=5.8. Plants are generally healthy, really green with plenty of new growth. I'm a bit concerened because some of the OLDER leaves are showing signs similar to nute deficiancy. They are turning brown and crumbly on the edges. It's only on the leaves that were from the original mother plants when I took clones. What am I doing wrong?. Should I be worried? Last reply by 420Downunder,

 Well my plants are about 1 1/2 - 2 weeks into flowering. Seemed like they were doing fine but the soil test kit said my nitrogen was depleted . Definitly why older fan leaves were starting to yellow. Just wondering if i can give it some blood meal 12-0-0 and thatll straigten it up. Also wondering if i should give Schultz Bloom plus a shot. Seems like phosphate is too high in it 10-54-10. How does having the correct amount of N-P-K affect yeild and potency? Looking for any responses. Last reply by S4mm1ch,

 Hi Guys ,, I am having problems with my babies . I am hoping someone can help me . I normaly grow in perlite but have changed to potting mix and am having these probs here and the harvest has really gone down in weight . As well as what you see in the Pics I have some little black flies in the cupboard . I am using Thrive as the Nutrient , PH is approx 6.5 using one of those cheap probe testers .

 The following was stolen from the once great WWW.OVERGROW.COM and my hats off to all those that helped in making that such a great place...... Now to pump this place with the info that i stole from there. Nutrient Disorder Problem Solver Version 1.1 - Feb. 1998 - distribution okay To use the Problem-Solver, simply start at #1 below. When you think you've found the problem, read the Nutrients section to learn more about it. Diagnose carefully before making major changes. 1) If the problem affects only the bottom or middle of the plant go to #2. If it affects only the top of the plant or the growing tips, skip to #10. If the problem seems to affect the enti… Last reply by Shithappens,

 hwdy. regular reader, but need help. started my first indoor soil grow. goin great, but have the tips of some leaves curling down and the leaves feel pretty dry. My first thought was the light was too close. so i put that up higher. Reading through the archives it could be an iron deficency. To help that, the info. says to set PH to 6.5. But doesnt say to set the water to 6.5, or check the soil ph. If I add water adjusted to 6.5, will that adjust the soil ph to 6.5??My first soil grow so kinda wingin it. Ta guys..

				This was a reply to a thread that I posted, where people were discussing h202, pythoff, and food grade h202 etc. I did a fair bit of research on this and this is what I came up with. K firstly I have used H202 for around 2 years now and only recently switched to Pythoff. Im not saying NOT to use H202 but rather that there are better things that dont hurt the plant. Heres a little bit of why- First, the food grade H202 shouldnt be used as it is not designed to be used in a horticultral area. Reason being is that food grade contain a stabiliser and also preservatives. which are no good for a plant. People are kinda right in thinking that when added to water it creates… Last reply by keepleft,
