ok so iv just come up on three weeks into flowering and my leaves on a majority (not all) of my plants has started to turn from darker healthy green, to a faded out green thats almost turning to a yellow.

my first thoughts were that i could have some type of N deficiancy developing since iv been giving veryu little of the N based nutrients and upping the P an K.i also thought that it could be a sulpher or similar trace element deficiancy as i use distilled water with 0 PPM to start.

any thoughts or advice will be greatly appreciated :bigjoint:

heres the picture of two leaves for comparison. the picture looks darker than it is, the dark leave is slightly greener, and the faded leaf is a bit yellower than they appear

leaves yellow for all sorts of reasons and each different shade can be a deficiency or too much of a number of different elements. you need to post pics (or nobody will answer you) so that people can see exactly whats going on, then you should get some solid answers

hmm its either a small N deficiency ( but i usually lean towards that) otr the beggining of nute burn but that seems unlikely.

what water, nutrients and soil do you use? how often dou you water and how often do you give nutes and how much? (a PPM reading would be great) and what is your RH in your grow area

EDIT: but notice how the yellowing of your leaves is WAY different than mine? ya those are completely seperate developing problems whisch is why pics are necessary :mrgreen: if you waould have treated them the same as mine, your plant probably wo

rh unknown mine broke two days ago .. but its not high i know that for sure cause its 75.. and im in a colder region so furnace makes it really dry in the house ... ppm never had used one ..i water usually evry day with phd water and superthrive the first week .. probably 80-100 ml water phd 6.0-6.5 ... regular organic pootting soil for indoor blooming plants.. 1/4 strenght ff tiger bloom, and 1/4 strentgh open sesame ff...i gave half nute mix and half water so 50 ml of nute 50ml phd water nutes phd as well .. i want to tranplant it with the others tomorrow into better grow media ..i think its the drainage throught the media ..im used to groing in cubes then into a soilessmix and or hydroton.. but life happens and had to start over sucks .. i try to keep the soil moist and not let it dry out dry out ..

ok well first off dont water everyday, you want to soak the plants soil once but then let it almost completely dry out before you water again (this not only prevents root rot later on but makes the young roots stretch deeper in search of water= good). i would stop giving them nutes for a week, a plant that small doesnt need anything really. see how they are after a week of no nutes then make a decision on them. as for growing medium, id use fox farms organic soil, mix in a good amount of perlite and also put a layer (maybe a half an inch) if river bed rocks at the bottom of your pot, this will do amazing things fr drainage and root structure.

remember your RH needs to be about 70% (pretty damn high) during veg and about 50% during flower later on. you also mignt want to look into beneficial bacteria addatives such as prozyme and great white. these will help with root strucrure, gas exchange, and nutrient waste buildup giving you a much more robust and healthy plant

Edit: also i wouldnt transplant until your plants are about 8 inches tall, theyll be fine in the solo cup till then. only transplant now if you think that the soil is too compacted for water and air to get through and you think it will kill the plant. however transplanting now wont hurt it, but it will be harder to gauge how much water you need to give it, which could be critical with such a baby

actually though, your soil does look pretty dense, trasnplanting might be a real good idea. at least give the sides of the cup some squeezes (not too hard) to loosten up the dirt, also i forgot to mention that you need holes in those cups (couldnt see any) put 3 small holes on the botom and 3 about half an inch up on the sides of the cup

yeah this is an experimental grow 12/12 from seed like this bad boy is 41/2 weeks old ..and has pistals all over it idk im going to try an get bacteria just short on doe .. thats what i was thinkin but i wasnt sure cause i always grew hydro .. just had my bro hook up the timers and stuff but that all got wrecked in a flood all my shit probabaly 2 gs was one week a way from harvesating like 40 plants six ft tall full of bud .. all the money i ssaved went by by .. so thats why i have to do it cheap..thanks for the input i just never had a problem with to much water and or drainage .. sucks thanks though a lot

ya thats a huge key is drainage. when the plants are in dirt the water blocks oxygen from getting in when its super damp so your root sytem starves for oxygen and once damaged they dont absorb nutrients as well. but ya just let the water drain and dry and dont use nutes for a week and i think youll seem some good improvements. keep us posted on how there doin!
