I can't really see the yellowing in the pictures; is it the whole leaf that is yellow? or just the tips. If the whole leaf looks pale green/yellow, you need nutrients. Start at around a 25% concentration and every week increase it a little (around 25%). If the tips are yellowed and/or dry/crackly, nutrient burn is most likely the problem and reducing the concentration should remedy the problem.
gainesvillegreen Reviewed by gainesvillegreen on . Yellow leaves, burnt tips, and pics Hi everyone- I read before posting but I'm not sure what it is still. I know that some of you will see the pics and know immediately. I have two separate veg kits in DWC. Two days ago the leaves in one veg kit (White Widow strain) were looking yellowish. The other kit (Northern Lights strain) was looking good, but there are purple stems on both. I emptied the tanks and started nutes for the first time. BC Grow with BC Boost. Minimum PPM. Now today, the White Widows look even Rating: 5
