Second Opinion

[SueveRico]

Hello everybody this is my second post here and my first grow. I am 4 weeka into the gro from seed. I believe this is a magnesium deficiency but I want to have a second opinion.

I am using half fox farm light warrior and have OF. With 30% perlite.

I just watered her with 6.5 pH water and the run off was 6.1

I have a 250w 6400k CFL with reflector on top and 4 23w 6500k 2 on each side.

The stems are red and in many leaves the veins are red.

A week ago I got paranoid that I was going to lock her by putting too much b-52 so I provided a flush.

I have pictures below any help is greatly apreciated!

Rico-- that looks more like P defc. to me, and the overall light color on the lowers hints at something else, too generic a symptom to tell exactly what yet,... I need more info about what you're feeding, and how much,... As for pH, run-off testing is generally usually inaccurate for several reasons, but following this guie will help get a better reading-(https://www.autoflower.org/threads/...-testing-and-ph-estimation.41733/#post-928975 ) .... otherwise, the best thing to use is a soil pH probe, for direct measurement,... Accurate 8 makes a good one for the money! A word of caution about soils- they're showing to be badly acidic these days, many many complaints from others,... so, first thing to do is get an accurate pH reading, then we figure out if you have a lack-of defc. issue, or ph lockout issue,...

Thank you for your reply. I just strated feeding micro grow and bloom from advance nuttiness at 1/4 strength few days ago. I was told that OF had a enough nutes to take me to 4 weeks.

I also was reading lots of complaints on OF I wish I knew ahead of time. Is there a soil that is better for auto's?

So, micro and Bloom are the only nute's you've added? If so, she's hungry for other nute's,... Soil choices depend on what you have locally-- list some and we can offer opinions...
