Having a few issues with my babies

Whats up guys!

Pretty new to the forum! Been scanning the site and reading threads for a while now but have yet to post anything, so here goes;

I'm 5 weeks into my second grow, 1st grow was big buddahs super automatic sativas... lets just say I fell in love with this new hobby of mine :D.

Anyways, second time round I decided I wouldn't be growing autos. So I currently have 4 photo plants (all different strains) on the go at 5 weeks into veg... Barneys Farm Pineapple Chunk, Barneys Tangerine Dream, Nirvana Swiss Cheese and Bomb Berry Bomb.

- biobizz all mix soil
- 5 gallon smart pots
- water going in at a ph of 6.5
- 20/4 light cycle (600 watt hps bulb, adjustable ballast working from 250w, 400w, 600w and overdrive) (first 3 weeks on 250watt, currently at 400watt)
- started feeding at week 3
- biogrow at 1ml per litre
- magne cal at 0.5-1ml per litre
- feed, feed, water, feed, feed, water is the cycle I will be running.
- roughly 4 days between waterings

From around a week old, I started having issues with pineapple chunk...it was a much lighter shade of green, almost lime green. Im currently at week 5 now and it is still a much lighter shade of green, I had a serious case with all the leaves clawing down, (which is still happening but not to the extent it was) and currently also having issues with dry crispy brown patches on leaves all over the plant, not every leaf, just random ones it would seem. This issue seems to be happening slightly on my other plants now too. Its hard to tell if it is all the same issue as they are not all showing the exact same signs of stress. I don't know if thats because they are different strains though.
Berry Bomb appears to be a very very dark shade of green in the middle of the leaves, getting slightly lighter toward the edge of the leaves, its very strange, almost as if it is being dyed . Swiss Cheese is also very dark green but doesn't seem to be showing the same leaf symptoms as the berry bomb, it is however getting dry brown patches on and the tips of the leaves at the bottom are a definite yellow colour.

I have taken some pictures to show what I mean, I hope this helps to clear things up a bit more..

Also, it is worth noting I just checked the soil ph of the girls, pineapple chunk is at 5.7 (possibly locking out phosphorus)???
Berry bomb - 5.8
swiss and tangerine are sitting in the low 6's. Not sure why I haven't checked that before and also not sure why the chunk and berry bomb are that low.. ideally I want these to be around 6.2-6.5 right?

Thanks in advance!

It looks like a possible nutrient deficiency.. But before you decide to start treating for nutrient problems, make sure and examine extremely close for pest problems.. Hopefully they have there own growing room and your not growing where your taking the pics.. Also, if your run of ph is that low, try bumping up your ph a bit and get your ph around 6.3-6.7 (doesn't have to be exactly one number, jus keep it there in that range)

can you check your soil ph? the leaves currling under usually means your ph is too high.

the last plant in the last picture is drowning for shure.

picture #5 looks like the plant has nitrogen and manganese deficiency's, which makes since because manganese can be blocked out with high ph levels.

Thanks man, these have been my thoughts too..!

Nooooo, I use a 1.2m tent to grow. I actually noticed a tiny black fly in my grow room the other day and thought that I may have fungus gnats...but I have searched high and low and have not seen any since.

Il try watering at 6.7ish to bring the soil ph up a tad. Thanks for your input dude.

Yeah man, as i said PH is too low, not high haha. Also it has been 5 days today since these girls were last watered...and that was 350ml, before that they were on 250ml for a few weeks. They are definitely not drowning...

I wish I could grab some better pictures.

I would say overwatered also, it also looks like you need less fertilizer and some calcium to balance it out since your getting the rust spots.
