Starting signs of problems? Newbie grow

Sick Plants & Problems
#1

Starting signs of problems? Complete newb grower here.

Temps have been a consistent 75f and RH is 45-50. Lighting is under t5 4 bulb 4 ft long.

Started this white widow in nothing but HP pro mix and ph tap water to 6.5.

It started to have a lack of growth because I believe I let it go for to long in a small pot and started noticing signs of what looks like to be brown rust spots and little random white spots. Plant is 18 days old from seed. I transplanted into a 5g pot of 50/50 mix of pro mix and happy frog and gave its first feeding over advanced nutrients sensi grow A and B @ 2 ML. I think that may have been to much as it may be starting to show signs on the tips of burn.

Start feeding these plants.

Pro Mix all by itself probably does not have sufficient nutrients for the life of a plant.

Good luck bro.

Welcome to OverGrow @Bestbudz! 99 is correct, they need food. Happy Frog’s NPK ratio is 4-1-7 iirc, so your 50/50 mix of media would be like 4-.5-3.5. Not enough nutrients imho. I was feeding my WW’s 8ml each Sensi Grow A+B and 1 tsp Epsom salts at day 18 (99-22-122-39-69) N-P-K-Mg-Ca.

Those spots look to be the start of a Mg deficiency ime. There’s no Mg in the Sensi Grow. I’d mix 1 tsp Epsom salts in a gal H2O, add Grow A to the solution, then add Grow B. Check EC & dilute to your preferred EC (.6-.8). they should show improvement in a couple days. Hope this helps. Just my .02!

Thanks just to clarify I didnt start the seedlings in the 50/50 mix i started them in just straight HP pro mix if that makes any difference

Just noticed now how much Golden Tiger seeds resemble Audrey II.
