Proactive as in trying to predict what is to come. If your plants are growing out of a young stage and into an adult stage, naturally they will require more salts. If they are very young or in a state of late flowering, then you need to back off, or, you'll screw them up with no chance of recovery.

Reactive is watching your lower leaves drop because you've been using some cannabis miracle bloom food which is really designed to promote leaf drop ("they" don't tell you that). Takes time (and money) for folks to realize it. Lessons hard learned for the noob who's letting themselves to be taken advantage of, vendor does more trips to the bank for deposits - it's all about the money.

That's the worse place to start. You need to research plant nutrition in hardback or on the web.

Nope, I'm saying you need to understand plant nutrition and then compare what you've learned with the crap you read off the typical label.

You'll just have to learn Botany 101 on your own. Aint mah yob mah man.

Waste of time.

I have no opinion on "supercropping", but if I had to lean one way or the other, it would be that's it's just another forum gimmick. If it sounds good, then it's gotta be, right?

Hi Uncle Ben, thank you for creating this thread! I have a quick question for you if your not too busy.

I have recently discovered some leaves om my plant which is about 12 days old, they are starting to look copperish and coupling, is this due to over watering?? i'll post pics and maybe the link to my grow if u want to check it out. Any advice is very appreciated, thank you for your time.

From those pictures it could be over nuting or over watering. Are you giving fertilizer yet?

no nuts yet, the copperish colour could be over watering, i find i have to water daily, dry soil. Temps have been from 79-90! i have it stable now at 81, humidity is about 44%
i have them on 24/7 right now until day 16 which is this weekend.

Always interested to hear from UB, as he will set the record straight....

But what kind of soil are you using? It appears that you using a time released soil by observation of your pics? If so, this obviously already has fert in it. When your medium becomes dry (you stated that it was becoming dry daily), this increases the chance of nutrient burn when the plants are young due to increase in salt concentration w/in medium. I experienced this in my previous grow b/c I started out using a MG soil that contained time release nute's... IMHO, I agree w/ Jack, nutrient burn.

It shouldn't be over watering, given your information is correct. If the soil is truly dry... Compare a container that you have just planted, no water; to a container that you just planted, watered. Weight of container is one reliable way to tell. Sticking your finger deep into the soil an inch or two, is NOT reliable.

Keep in mind that I myself, am a new grower. So, take it for what its worth. Just trying to pass along my recently learned lessons. Cheers!

It's some type of leaf scorch. What caused it is your call. Did you get a light too close to the leaves?

You're bound to have some nutrition in your soil.

Solid advice dakin3d
