White widows week 2.5 of flowering (12/12) 600w light
Feed using floramicro / floragrow and floraflower . 2gallon pots fed 1 time a week with 1 litre of water/food... spray in between on surface of soil and leaves... may add small amounts of water in soil as well if needed...

Ok so I've noticed now all my plants have some yellow spots everywhere. One of my plants also has a slight spot with a brown leaf on it. Here are some pictures... let me know what may be the cause..
I do mist spray them from time to time... my grow room with a humidifier is maybe at around 30% humidity so not too worried about mould... I've also noticed that when I do mist the plants and add a little bit of floramicro the plants get darker in colour and seem more healthy, could that be the cause of the yellow spots at the end of the leaves?? Anyone with

Looks like it could be nutrient burn. Are you PHing before you feed them? Also do you alternate nutes with just PHd water?

NO I don't ph... I use filtered water from my fridge. figured that would be good enough... and what do you mean by alternating nutes.. I only use the ones as stated above mix it with the filtered water..

So instead of doing nutrients every feeding, you should alternate with just plain PHd water.

You need to ph your water/feed just because it's filtered doesn't mean it's within the acceptable range. And I believe he's wondering if you water with water without nutrients every other feeding. Also stop misting them now that they're in flower you could end up with bud rot later.

Big no no man all water you feed your plants needs to be ph'd reason nutes will raise and lower ph. if you're feeding once a week you are over feeding ,feed water feed water and at weeks 4 and 7 I always flush 3-5 gals of water trough to flush salts out then maintain normal schedule until ready to final flush and harvest I always have stinky as fuck sweet tasting green gold

I'm only following the feeding chart on the floragrow chart... says to feed once a week... i fed them last Sunday. .. the one coming up I should just give them water? aLeo say I do ph the water when I mix the nutrients... how can I regulate if it's too high or too low... should I let the water sit for a bit.

I go feed, water, feed, water. Each time it gets pH'd. And there's usually a day or two between them. Though with a soil, coco coir mix like mine. I should probably space that to about 3-5 days between watering/feeding.

No two mediums are the same. So it's really about figuring out when the soil is dry enough. And when your plants need to be fed.

You can buy ph up or down, I use apple cider vinegar to knock mine down to 6.4. Also when you water do you allow any run off? I do straight organic so I rarely do however synthetic nutrients need 20% to help keep you from getting salt build up. Do you use any cal Mag? You have city water or well water? If you have city water you need to let it gas off the chlorine which is just sitting it out24 hrs before you water.

Yea I allow about 20% run off... using city water. thanks for the advice will start doing a phone check

Everything you do when growing plants is all experience you're never going to get it perfect every time pot is a hardy plant and also a gentle plant some take a lot of food some take hardly any trail and error

looks like water drop burn.... from spraying the plant and letting it sit under the light the water drops acts like a magnifyer and burn the plant....

Just get a ph pen and some ph up and down and that should clear up without any problems. I feed every time I water but I feed at about half to three quarter strength.
