First Grow - 125W CFL Bagseed

My plants are four weeks into flowering as of today.

I've noticed my new leafs are a little yellowish and some weird burning on some of the fan leafs. Google led me to believe this was a P deficiency so I added 4ML of Dyna-Gro Bloom to my watering yesterday.

It's sitting in a mixture of Coco-Coir and Perlite in a Smart Pot.

I'm also seeking general advice to get the most out of this young lady!

A little yellowish, or definitely yellowing?
Growth tips and highest fan leaves yellowing is usually a sign of iron deficiency, sometimes caused by lack of iron in the medium or ferts, but more often by too high PH locking out iron absorbtion.
Are you monitoring PH?

Agree, hows the Ph?

4ML of bloom nutes..... to how much water? What other nutes has it had? Coir n perlite aint got nothing to offer it, it aint promix....

This is why I went hydro.... no soil Ph kits, no wondering just what nutes are in the soil..... I have digital meters for that shit.

Yes, I th

The PH is somewhere between 5.0-6.0 I know the best range to be between 5.5-6.5 for Coco. The Ph actually was a little off for awhile there until a flush I gave it last week. I had been under watering and spiked my coco.

The bloom nutes went into one gallon of tap water then PH'd to approx between 5.0-6.0.

It's hard to dial the PH in precisely because I use the color test kit, all I could afford sadly.

I got like a $12 ph pen on amazon.. (2-3 actually lol) and I got a friend who spent the dough on a bluelab pen...

Expensive pens are nice..... cheap ass pens work just fine. (Just remember to check calibration like weekly, lol) ((7.0 and 4.0 so its accurate))

The drops arent terrible, very accurate, no calibration to drift off mark......... but when you add colored nutes, things get sketchy... I wasn't a fan...

and try to eyeball your target more in a 5.5-6.5... My happy zone is 5.9 /shrug but I am DWC.... soil likes a mid-high 6...... coir...... I dunno, coir kept giving me calmag issues and I got frustrated, not sure where it prefers... but definitely always above 5.5 in any medium....

May wanna browse a thread or 2 on coir growing, see what others run for nute Ph.... more trustworhty than my stoned ramblings

(on that note, live plant extract run off deathstar.... awesome... <3 lightskyfarms)

Im no master grower by ANY means but that looks pretty nice to me!!! Youre not very far off!
