Newbie in need of some help. My gals are dying!

Hello all. Long time lurker and first time grower here.

I am having some problems with my girls that I'm hoping someone out there can help me with. The symptoms appear to be a lot of things and as such I can't pin down what the problem could be. I have been using growweedeasy's symptom checker but my plants are showing signs of being a number of things.

The strain I am growing is Auto Robocrop which is supposed to be very easy to grow, but so far things aren't looking to great. They were planted in Plant Magic soil from seed and started out looking great but no longer. I have been using Biobloom Organic nutrients.

Anyway take a look a few pics a snapped and tell me what you think. Any words of wisdom would certainly be appreciated.









To clarify I am running a 400 HPS on an 18/6 schedule and my daytime temp is 26C and my night time temp tends to sit around 15C. What could I possibly be doing wrong?

Thanks

Check your runoff water ph

Run off PH appears to be about 6.5. I am only measuring with PH strips so it's not exact but it's around that.

How much of the nutes are you mixing per gallon?

With my last watering I did not add any nutes as I am worried this issue may be nute burn. But before I was adding 2ml to a 4 pint bottle. I have been quite light on the nutes up till point because the plant magic soil I got was supposed to be packed with enough to last well into vegging.

These girls are autos which as far as I'm aware stay on 18/6. This is correct, right?

Yes 18/6 is fine, i ran mine 20/4

A few questions to see if it might be over watering which can cause nutrients to be locked out.

How often do you water?
How much water do you give each plant?
What size pots are those?
Do you water all plants on the same schedule? Exc: Every 3 days, or every 4 days?
Do you use any methods to know the pots are dry and ready to water?

ph issues or too many nutes. If your leaves are dark green you can assume you are feeding perfect/heavy. Nitrogen is the main nute uptake. If your leaves are dark green and you have plant issues then make sure your ph is 5.8-6.3 and do a flush until the leaves lighten up or until new growth kicks off.

kinda looks like N toxicity a little.......

you getting rust spots on the leaves, does it smell like "hay, or grass"

Soil should be ph'ed closer to 6.2-6.5.
Hydro is a bit different, which I don't know as much about because I'm a soil grower but hydro ph should be closer to the range that you suggested.

To the OP,
May be overwatering causing nute lockout like @Buba Blend mentioned, I'd answer those questions he asked and then we'll know if we can toss out the possibility of overwatering or not.

I saw that I made a mistake with my numbers for pH and I corrected it. I tend not to drift into the 6.4-6.5 range because 6.6-6.7 is out of range. I grow closer to 6.0-6.3. If you’re using a drop test kit for pH or if your meter is not 100% right the 6.4–6.5 pH range is too close to the edge of optimal.
