Question on colour of leaves

[Doctor Herbert]

Best advice at this point, is don't overspend.
Keep it simple, it's a weed.
Does not need supebloomkaboom snake oil to do it's magic.
Clean air, tap water, dirt, light, and love is all you need to grow great weed.
Best to put the money into a decent PH meter, of even the PH test strips,
And you will want to know a few things about your tap water.
P.P.M., PH, and Ca/Mg levels.

Then, settle in for a long winter's read.

The first link in my signature takes you to the archives.
Everyt'ing ya need to know is there!

Read until your eyes bleed
and you'll never again have to buy your weed.

Again sir, I thank you! I've made 3 cuttings and followed your advice! I will read up on everything and I've started watching Jorge Cervantes' dvd's. Great stuff. I've you see a huge cloud of smoke coming from the south, that's me smoking my crop, lol.

Doctor Herbert Reviewed by Doctor Herbert on 07-26-2011. Question on colour of leaves On one of my plants, the tips of the leaves are turning yellow. I'd say about a millimetre's worth or so. Is this due to lack of N? Any help would be greatly appreciated. Thanks! Rating: 5

I also use a plastic bag sometimes too over the odd spare cut and it works great.

Love your attic space Doctor H! I'm jealous of all that room

Thanks! it's going to take a lot of work but I'll get something going on. I'm starting today to build something because here in Buenos Aires it's winter (min 35.6 F max 68 F) and ever since I saw Cervantes' vids, I learned that I needed a circulating fan for the ladies and that dramatically reduced the temp in the grow area (the lights were giving all the heat).

All this that I'm doing is for personal consumption, I suffer from headaches and this medicine helps me. Plus, here, buds are really expensive, 90 dollars for just under half an ounce (1 dollar is equal to 4.19 pesos). All that I can get is pressed crap that sometimes is good, but most of the times it's crap.

I have 2 final questions and I won't bother you guys again (thanks for all the help, I really appreciate it).

My first question is when should I start the flowering stage? the indicas are 15 inches tall right now.

And my second question is are these female? I think they are, but I want to confirm

Again, thanks for all your help guys. After this, I'm all good to go!
