Problem with the green.

Actually im a first time grower. Untill recently ive had great luck with my 3 babies here. After sighting a small whitefly infestation i ran to my neighborhood hydro shop and picked up some things. Im currently running 1 200watt HPS suplimented with a 65watt grow light. Using small parts budswel 0-7-0, Foxfarms Fruit and flower (5-8-4) and a shultz 10-15-10. A few of the new fan leaves have begun to get slight necrosis and curling. Ive moved the grow lamp up (from 6 inches above tips of plants) so that it is almost at the same height as the HPS lamp, roughly 26 iinches from the tips of the plants. I have noticed the water i am using to feed the plants has left quite a few calcium and/or sodium deposits on my mylar backing.
So heres what ive tried. Ive tried cutting back the feeding a bit. I have let the plants dry completly and have rinsed the roots out with the reverse osmosis water (high calc/sod possibly). The soil PH and NPK levels are all within reason (nitrogen is a bit high but thats what im going for). SO im gona try to flush them with some distilled water and see if anything happens. But i still havent pin-pointed the problem. Any advice would be greatly appriciated.
thanks.

 

I am assuming you are in flower if using budswell and fox farms bloom.If this is the case and you are adding the shultz as well ya may very well be overferting.Do the flush as ya stated and start up again with half strength flower ferts and I think you will see things clear up.Quit using the shultz.If your not in flower but veg then your giving them entirely to much P,K.Quite the flower ferts till in flowerand use the shultz alone.Deficiencies begin showing due to lockout from overabundance.

 

Indeed im still in the vegitative state. Im not using full strength budswel or the fruit and flower.. just a slight sprinkling over the top of the soil due to low PK levels.

 

Your plants dont need that extra P and K while in veg,to much of either of these can and will lock out other fixed nutrients which is probly the cause of your deficiency..I recommend getting some veg ferts,even the shultz at 10-15-10 has way more P then the plants need for veg and being a chem based fert all the worse.Get yourself as example some fox farms grow big 6-4-4 or earth juice grow 2-1-1 to avoid these probs in the future.

 

Heres a few pics so you can acuratly judge the plants condition and the grow room.
As you can tell it stays VERY dry in the room with an average temp of 82.5F.
any further imput would be lovely.

 

That small of plant does not anything besides what's in the soil. Soak them good with plain water then wait a week. They will perk up fine.

 

I didnt like the clumsyness of the shitty grow "box" i had going so im doing some renavations. Getting rid of the cover over the plants and switching it up a bit. The small space i had was giving some heat problems. Ill post some pics when im done to see what yall think.

 

what could be causing this? heh im lost here. PH is 6.8, NPK is where it should be. Ive leached the salt out, and i bought Indoor Marijuana Horticulture yet i still cant pinpoint this problem. The very bottom of the stem is starting to discolor. This plant has been this way for about 2 weeks.. Im ready to plant another, but i wanna know wtf i did so i dont repeat this mistake.




my healthy youngin.
