Can someone help diagnosing the plant?

Hi guys

I'm 8 days into flowering after vegging for 8 weeks. Few of my plants are showing deficiency signs and no matter what I do to try and correct them they seem to stay the same. They are in 12litre pots, watered every 3 days, only feeding 1/4 - 1/3 strength nutes on second watering. I have fresh air pump into the room and extractor fan along with oscillation fan to circulate air. The PH is 6 and I have added calcium and magnesium to the water for the past 3 weeks. Temperature is 20-23degress. The leaves are limp and feel like paper and all show signs of yellowing, one also has a few brown spots (please see photos)

Can anyone recommend what forward action I should take. Thanks.

The brown marks aren't as dark as that and there is only 4 on the whole plant. The yollowing i put down to Cal and Mag, but even since adding them to the feed there has been no improvement.

It's green lol.. see any pests I just had a plant start looking droopy and just unhappy and I didn't figure it out till it was too late I had a infestation of bugs in my soil chomping at my roots they stay in the dirt till watering or till u start messing around with the top of soil look really good for them best of luck

If nutrients aren't solving it then its probably not the problem and check other things like the environment or overwatering or did i just fry them with my 10000w flowering bulb etc etc....

Thanks guys. i purposely didn't water for 5 days and it didn't seem to help much. They have ample space in a 3m by 4m room under 2 600hps, and never water until soil is dry.

Yeah, vegging for 8 weeks, they're roughly 4 ft high but have quite a bit of stretch. I've been using organic feed, do you think that could be a factor? Ta

How damp is the soil when you water feed?
Nutes should be veg nutes still and it goes water - feed - water - feed etc.

Soil? Coco/hydro?

pH of what? Water/feed solutions? Soil? How are you figuring if it's the soil??

What nutrients?

I'm using Iguana organic feed and added cal/mag since the leaves were showing signs of yellowing. The soil is plagron all mix. I have always water - feed- water -feed with avaerage of 3 days between watering (sometime more) depening on how damp the soil is around the root mass. I test the level of the PH by getting my water/nutes solution to PH 6 and then mix with the soil of the plants from around 6" down, leave to settle for 5 minutes and then syringe the settled soil/water mix into a test tube to mix with indicator to test PH levels. I don't have a gauge to test RH at the moment, but will pick up one on Monday, it is a fairly large room with a good air flow and circulation by using extractor fan and fresh air input fan. 600w HPS bulbs are far enough away to not induce heat stress.

Thanks for help

Your organic = pH don't matter...Soil self pH's.....If your real nervous. Simply pH feeds/waters to 6.7 and forget it....

If your soil is running low (kinda sounds like it) I would do the adjusting to 6.7...
6.5 veg and 6.7 bloom.
NO bloom food for the first 2 weeks and 50/50 for the next week then straight bloom...Get some fresh bio's in there. Make a simple bio tea or buy one with active/live bio's and use it. It'll help the soil self pH.

I know what the problem is . and why they look like that . this can lead to a serious problem. I do not want to get all technical with nutrient numbers formulas . I don't want to get all science out . ( THEY ARE SICK ) hope this helps out use this for future plant problems and formulas . suggest making a journal .

I have a journal, I write everything that I do down as so as I do it. Do you know why this plant looks like this? Thanks
