What's your pH? Are you feeding them, you need to give every detail you know about your plant along with pictures if you want quality help.

i told you soil water food temps and prob. how much more detail can i get into?are there dozens of things that make new growth yellow?like as the new node appears and starts to open the middle is yellow.and i dont have my camera so can't do the pic thing...didn't think the words would be that hard to understand.(hope that didn't come off assholeish,i have much respect for both of you and thanks for responding)
p.s. i thought lime made soils ph neutral?same with r.o. water so how could it be a ph prob?i don't know.indoor is complicated,i am used to digging a big hole and putting a seedling in and letting mother nature take over(with my occasional feeding and watering with creek water

pH is one of the most important aspects of outdoor growing. Check this out http://boards.cannabis.com/plant-problems/109869-need-help-come-here-first-i-have-answers.html it will get you started on pH knowledge, and how pH problems can be shown as every possible deficiency. We NEED to know your pH of your water, your feed, and your run off.

turns out..........light deprivation!i had been gone a few days and my timer died.3 or 4 days of darkness seems to slow chlorophyl(?)production way down.

im having a similar problem with my bubblegum strain. i have attached a picture as to increase the odds of possibly identifying what the problem may be.....

they are growing in cocoand are receiving a aact once a week, nutes between along with plain filtered water.

just tested the ph runoff of a fresh water rinse: 7.06
ppm: 648
i feed heavy 16 bloom a and b and prime, humbolt's deuce deuce, ginormous, and honey.
the tea feed gets brewed with ancient earth by GH, molasses and sea kelp


any ideas brother?

any ideas brother? 648ppm without any nutes? thats too much,any concentration higher than 10 ppm in water . is too much for me.

[piecemasta]

that was the ppm of the run off not the ppm of the water the plant receives

[piecemasta]

i am worried about my bubblegum plant. it might be a sulfur deficiency!?
water every other day with RO water

HELP! more pics of plant with lights out so the hps wont effect the color
