hey there brotha... i came up with a few things..
::in response to another post from another thread::
i sorta skimmed to these pics.. so i am sorry if i answer a question you already have had answered or addressed...
it doesnt look like you have a def... more like slight nute burn...
i know the recommended dosage is what you are following.. but that makes for a STRONG solution... it is terrible to follow...
based on what i use for my 55 gallon reservoir i use 48 tsps of micro and 72 tsps of bloom (i'm flowering obviously)... now i use other additives to... so i am sure if i didnt use the additives i could use more... but based on what you use for your 10 gallon res, if i used it in my res i would have to use 96 tsps of gro, 46 tsps of mirco, and 20ish tsps of bloom (i am flowering.. but those would be the equivalents if i was vegging.. or switch the bloom and veg amounts..), plus the additive you are using... basically it would cause a high EC/ppm environment.. which isnt good... try cutting back to about 13 tsps of gro and up the micro to about 8 tsps, drop the bloom all together, stick with what you are doing with the additive, and fill the res all the way up...
now you may want to flush them for a day or so with 1/4 strength solution of what i just said... this will help remove the build up of salts and get things back on track faster...
secondly, your girls seems a little over watered... so that means you should try to cut back 1 flood you do a day.. or that there maybe some standing water in the sites that needs to be drained out better...
thirdly i would recommend keeping the hydroton at or just above the flood line... this will help support the plant as well as give more room for the roots to grow...
fourthly if you dont have an air stone you need to get one... keeping the nute solution with aerated and moving is a good thing....
fifthly plants can absorb co2 with direct air flow.. i have a stanley fan pushing air into my grow directly on my plants.. i have a wall mount fan that blows directly on my plants.. and i have another floor fan in the back of my room that blows directly on the plants.. the problem isnt their ability to absorb co2.. its the amount of co2 in the air that is present to absorb.. warmer air holds less co2... and the temps you are hitting are pretty high not to have either a fresh air intake or co2 supplement... keeping the fan on the plants will make the stems much stronger and keep the plants much cooler... now keeping a fan pointed at your lights will help dissipate the heat around them which isnt a bad thing... as long as the fan is blowing upwards and you have an exhaust fan pulling the warm air out.. but i would try to, if you can, either lower the temps, or figure out a way to increase the co2 level via fresh air or artificial supplement of some sort...
oscilating fans are good.... they move the air around more than a fixed position fan...
keep the fan going at all times.. this helps to keep fresh co2 is available always... co2 is used quickly by the plants and is needed in large amounts.. if the air around the plant becomes stagnant then plant functions slow... keeping air moving around them is a MUST ...
it would also help to drop temps if you can somehow... even if it means moving the reflectors around the perimeter outwards a little bit to allow more air to move around...
i think the reason that the plant with the foil under it stands out straight and the others sag is that the foil reflects the heat back under the foliage and increases the amoung of transpiration the plant does... this increase balances the extra water they are getting...
i think that all..
that was a lotta shit to say.. sorry if i seem critical... just pointing little things out...
