nonsense. using straight Maxibloom works awesome and i might go back to that eventually.
I don;t know why, it may me the strain, But they can't take 8-16, they take 5-10 in veg and they end up with deficiencies... and if I up the ppm they get burn... there is no in between...

I've been using Lucas since the beginning of my hydro hobby and have had no issues with it. I have been making it myself the last year or two and find the home made stuff to be even better than the hobbyist stuff at hydro shoppes.

i could really use some help guys, i feel as if I'm about to lose my girls at this point,
i was using Lucas @ 50% twice a week FWWWWF (watering twice a day,DTW, 7Gal Soil pots, outdoors),
i changed to three times feed @ 50% Lucas for current week FWWWF
growth seem to be stunted the past two three weeks,
some lower and mid fan leaves are turning light green / lime color,
with some lower new growth curling down

i currently pH @7 and water from the top,
i get the runoff @6.5 (using GH liquid pH indicator, its all i can get my hands on around here)

I'm so confused at this point at this point i need help getting my bearings together
they are about 9-10 weeks old

TIA

i used to pH to 6.5 without thinking twice, after a few weeks all large fan leaves turned yellow practically over night
i tested the runoff and found out the pH was close to 5 which locked out bunch of crucial nutes
i concluded the pH must be drifting; so i started to pH @7, my runoff then is @6.5 by GH color chart
ill try pH @6.5 for this week, i hope they will come around, ill update as soon as i see any changes

Make sure you flush a good 15 gallons through each plant if you feel they have gotten lock out. I do 10gal of tap and then 5 gal of Ro Ph'd at 6.0. You would do 6.5. Then check runoff

i guess a good flush cant hurt in my situation!

whats my best route as for feeding schedule; considering the system is
DTW in 7 Gal pots with premium peat moos
they are under direct sun with no light competition;
almost intense heat conditions (not desert like; but very hot)
i need to water twice a day as water evaporate fast;
i added clay tiles around the pots to dissipate some of the heat (seems to help)
i feed (F) once in three days @50% Lucas; then water (W) in between;
the loop looks something like this FWWWWWF (a gallon per pot)
i cant get a handle on how to adjust Lucas under these conditions

if still in veg take clones, move to ydro, start fresh, use different nutes... dyna grow, botanicare, canna A + B

good luck

what method you are using. DWC?
im used to NFT & DWC, unfortunately atm I'm running in DTW (drain to waste),
that's the root of my problem; i feel as if I'm half blind in DTW,
half the control's im used to are missing
