Pictured below is "Penelope" a Pineapple Express photoperiod, She is 8 weeks old vegging, and today is her very 1st day I flipped her over into flower 12-12 light cycle.

24"×48"×60" grow tent (tucked in a small wall in)

Please help... all I can do is pay it foward as I learn best practices. Screenshot_20200423-100656_Gallery.jpg

As far as lights go, I'd suggest getting a $20 Lux meter from Amazon. You want your lux in the 50k-60k range for flowering.

I switched from 3 part GH series to megacrop and won't look back. 1 powder. 1 feed for veg. 1 feed for flower. It's much easier and a lot cheaper.
Just this week, as my gallon containers of GH are almost empty, I decided, based on the recommendation of another RIU grower to switch as well. I went with Jack's 5-12-26, Calcium Nitrate and MKP. Items should be in my post box this morning. I'm quite excited to dial it in in my experiment tents and be free of the shackles of over priced bottled nutrients.

Only took me eight years to focus my research and studies on nutrients, but better late than never.

Agreed with calcium deficiency. It also appears to be very slight heat damage forming (sides of leaves curling upwards), but that diagnosis may be incorrect without more info.

I didn't see your temperature listed. What is it?

and I'm going to Amazon now to order the "mega crop"
If you have too much cash and too much time, go with a multi-part nutrient line. If you're looking for cheap, dead simple and excellent results, Megacrop is the ticket. You're better off buying direct through Greenleaf:


and available coupon codes:

Is that what you are feeding them? That's not enough and you probably don't even need the hydroguard. I'm surprised they are that green, maybe it's a misprint.
