Grow #5 - C99 (coco); Chemdawg & Cheese Candy (hydro)

Looks like deficiency of a few things but generally that occurs from either a lockout or severely underfeeding when so prolific. Do you know your drainage ph? What nutes and dose are you using? What is the water supply? What are your temps and rh like?
Mg deficiency (yellowing perimeter of leaves) Calcium deficiency looks like "rust spots", early signs of ca/mg deficiency are taco shaped leaves and upward curling of perimeter of leaves

Phosphorus deficiency (blotchy purplish coloring):

Potassium deficiency (like a burn around the edges of the leaf):


They look like 3-4 weeks in which is a time when most plants start to need heavier nutes and can start to transport nutrients from old growth prodigiously thus causing rapid necrosis. I've seen a few strains capable of sucking down leaves in a matter of hours.

Fuck. Yes colocowboy. Awesome guidance.

Thank you so much. I will feed her nice and heavy and see how that goes. I pulled a lot of the damaged leaves off.

Be judicious taking off foliage, remember that the sign of deficiency that your seeing is actually the transport of nutrients stored in the leaves. Letting the plant consume them won't hurt anything and helps buffer the lack of nutrient at the root. As far as strength of nutes I don't know what your using but going to heavy having been skint may cause burn, you should raise the concentration incrementally. Keep an eye and be patient.

puff, puff, pass

Will do. Thanks again!

What less are you using. Nice looking flowers for sure.

I assume you mean "lights".

So, I definitely have a more of ghetto setup right now. I have a a 2'x4-bulb T5HO with mixed 6500k and 2900k bulbs, a 135W LED (3w Cree diodes) and some 2700K CFLs. I know I could put in a 400W HPS or something and probably do better - but I don't want to deal with the heat and energy costs. I am going to purchase a 4'x8-bulb T5HO fixture soon that will pump out a lot more light and maybe increase yields and bud density. Someday I will probably give in and get an HPS, if for anything else just to try it on a grow to see if the extra hassles are worth it.

This whole thing here kind of turned into an experiment. I built the hydro system and wanted to dial it in and figure out how to best maintain it. I also wanted to see if I could just rotate clones into the open sites as I harvested the ones that were ready. This meant putting little clones into a system running at like 1400ppms pretty consistently. So far, I haven't noticed anything out of the ordinary. The only issue is that when you put a little clone in and the light is at a height for the larger plants ready to finish, it puts a lot of distance between the clone and the light and they can stretch like crazy. I started placing a 2700k CFL directly over the clones to keep the internodes tight and controlled which seems to do the trick and is easy to just clamp onto the tub by the clone.

Its been fun, but I am going to move on and grow larger/fewer plants when I receive my new light. I hope to fill a 4x4' space with a couple of plants SCroG'd in DWC buckets to see if I can get more weight.

This is all for personal consumption so I am just kind of trying new things and seeing what is most fun and works out the best in the end for me

Here are some current pics of the ladies in flower - the three in the front with the larger flowers are all Cheese Candy from Delicious Seeds (Cheese x Caramelo (Lavender) and they are great plants. Super sticky and very strong, positive effect. The younger one in the 2nd pic is an Afghan Kush Special:

Also, I moved that red LED to a side-light position because I notice that any plant under it produces some serious resin - like noticeably more resin then those just under the T5 or CFL.

Hey man I really like what your doing. I am new and I was reading on you Tangerine dream grow with the blackstar 135w. I am currently growing TD and Liberty Haze under a blackstar 135 and I am supplementing with (2) 2' T5's. I am growing in a 2'x2'x4'. Is two plants going be to much any info would be great I am going to veg for 1 month then flower I think. just looking for some advise from somebody who has used the same lights. I currently have a paradise seeds vertigo auto flower a couple weeks from harvest and it didn't take up too much room that's why I thought maybe I could grow two since they will not get to tall. I am growing in Roots Organics soil and using their nutrients. Temps stay around 75 to 80 and my PH is a constant 6.5 they are in 2 gal smart pots. Room is well ventilated. If I need to I have another space the same size I could put one in but it will mean another light to buy but I can if need be. I am hopping to get 3-4 ounces. Does this seem reasonable?
