my guess on your flowering plants is that they are deficient of either Magnesium or Potassium. Both of these deficiencies can look very similar. on your veging plant, i say Nitrogen or Calcium/Mag deficient...

Looks like they are starting to become deficient...? Some soluble Kelp & Humic Acid would probably do you some good... If your still in veg you could foliar the kelp, but add Fulvic Acid for foliar instead of Humic... I'm sure your ladies have used most of the nutes in your soil by now..

you are right about the optimal being around 85.... but this is only if all factors are perfect, ie light, co2 and nutrients... thus keeping it on the safe side down around 78-79...

if there are no hairs coming out of that there pod then male it is.. :cry:

so is the other end of your hood open?

thats to hot... should try to never go above 85 deg... photosynthesis slows down dramatically! 78-79 is my magic number when your extractor fan kicks on where is it drawing air from?

Yekke makes a good point, kelp is very powerful and is loaded with hormones. This is why it works great as a foliar spray during veg... but not during flower. If anyone is foliar spraying kelp during veg use fulvic acid in conjunction. Fulvic is a chelator and a smaller particle than humic acid...

i think topping will work great assuming she comes around... maybe in a few weeks...

unless it is a runt for a reason, like root aphids...? I find it best to get all unwanted plants, disease leaves, etc. out of your grow space. help cut down the variables, it can be tuff enough..

I would also recommend humic and amino acid but don't wast your money on those liquids, get a soluble powder. The concentrations are higher and you don't have to worry about how long it has been on the shelf degrading.

Soluble Humic Acid and Kelp are the only way to go. The concentrations are higher and you mix it fresh without worrying about how long it has been sitting on a shelf degrading before you got to it... Liquid humic and kelp is a total ripoff!

i agree with the pollack you should be up around 6.2-6.4 good to add calcium/mag to your ro water before you add your other nutes... a soluble cacium nitrate will give you the added nitrogen... next chelate the calcium with some amino acids!

A Virginian Tech study on Biostimulants shows that using Humic acid and Kelp at a 5:2 ratio work 50% more effectively than either product alone! http://archive.lib.msu.edu/tic/tgtre/article/2001aug6.pdf...

If you can get the brix of your plant above 12% it will not even be looked at as food by spider mites! This is ultimately where all gardeners should be... like they say "A healthy plant is the best defense against any bugs or disease" :bigjoint:

I agree looks like mites, although looks like you may have a deficiency as well...? If your a newbie i recommend Mighty Wash, there are other ways but this is probably the easiest..

be sure they are not getting to much nitrate Nitrogen, this can cause stretching... in soil amoniacal Nitrogen is usually a better choice... also what is your temp? if it is higher than it has been in past this would also cause more stretching...?

i have grown blue dream in the past and it is a very heavy feeder, especially at the stage you are in now! As it starts to put on more weight be sure it receives enough potassium, this is the energy element for plants. also i can see from one of your pics, you have thrips....

Advanced Nutrients is the biggest rip off in the industry hands down! Does anyone learn about plant nutrition when they use their products... not even close! They cloud the truth and make it seem like magic. I say grow up, learn the truth, save money, grow real chronic!

also looks more like rocks and wood chips then soil... hope you have more seeds...:wink:

Only water when the soil has dried out... take it easy your loving them to death! you obviously started from seed so they will need to grow for a while before they need nutrients, say 2 weeks or more..
